Eastern Army Aviation Group command was supplanted by direct divisional command on March 28, 1994, and remained so for the next seven years.

The 12th Helicopter Unit came into existence on March 27, 2001, the day after the former 12th Division was reorganized as the 12th Brigade and uniquely incorporated a heavy-lift capability following the JGSDF’s adoption of the integrated air mobile brigade concept. Aside from an HQ Flight and a 1st Flight now equipped with the UH-60JA, which remained at Kita-Utsunomiya, a new 2nd Flight was formed, flying the Chinook from the then newly established airfield facilities at Camp Soumagahara.

Strategically based in Japan’s centre for rapid-reaction deployment to any corner of the four mainland islands, the 12th Helicopter Unit’s primary area of responsibility covers Gunma and Tochigi prefectures and two in the Koshinetsu sub-region, namely Nagano and Niigata. As can be seen in the snapshots of operations on this page, when the disaster relief need arises, there is mutual reinforcement of the 1st Transport Helicopter Group at Kisarazu and the Tachikawa-based Eastern Army Aviation Group.

Having broken out on a plateau high on this 1,925-metre (6,316ft) peak at around 09:40, this fire met with a rapid coordinated response. The Nagano Prefecture governor made a request to the 13th Infantry Regiment in Matsumoto for JGSDF assistance in combatting the blaze at 13:00. This triggered the involvement of a total of 30 service personnel, 10 vehicles and five helicopters.

An eyewitness provided photos to a blog (link) account of events, which provides a good overview of the standard operating procedures. The scene of the fire being in Nagano Prefecture, the crew of that prefecture’s aviation unit helicopter (Bell 412EP*) received support from aircraft sent by four neighbouring prefectures: Gifu (BK-117), Gunma (another Bell 412EP*), Saitama (AS365N3) and Yamanashi (S-76B). In this case, use was made of facilities, including a specially provided windsock, belonging to the Kirigamine Gliding Society, which operates from a runway at an elevation of 1,680 metres, and the wide expanse of a ski slope in what was the off season. The water supply was drawn from the lake in nearby Tatenoumi Park in Suwa.

While awaiting the JGSDF, the local fire services and five prefectural helicopters had worked to at least contain the blaze. The load-carrying capacity of the bucket-wielding Gifu Prefecture BK-117 had left a lot to be desired, but both Bell 412EPs and the AS365N3 were equipped with belly-mounted Fire Attacker water release systems.

In the form of a 12th Helicopter Unit OH-6D, the JGSDF advanced guard departed Soumagahara at around 14:45 and sped to the scene to gather information. After a flight lasting around 30 minutes, a pair of 12th Helicopter Unit Chinooks arrived at 16:00, set down on a flat area in front of a winch shed and disgorged a jeep prior to the arrival of another OH-6D from the same unit. A TV camera-equipped Eastern Army Helicopter Squadron UH-1J departed Tachikawa at around 16:10.

Three-man ground crews attached the fire buckets, and the Chinook pilots literally swung into action. Making short work of dousing the flames—they dropped 47.3 tonnes in nine runs—the Chinooks and the other JGSDF helicopters were all stood down at around 17:00. Five vehicles and 30 men from the Matsumoto garrison, which had departed at around 15:10, had only just arrived at around 16:45.

The cause of the fire had been a strong wind that had blown sparks—from a supposedly controlled burn-off within what is a quasi-national park—outside the prepared safety area and set alight to 154 hectares (380 acres); luckily, no one had been injured.

* Sad to relate, both of the Bell helicopters that participated in this operation were to be lost in fatal accidents: Nagano’s Alps on March 5, 2017, Gunma’s Haruna on August 10, 2018. (See the Bulletin Board pages of this website.)

A Gunma Prefecture governor request for assistance sent to the commanding officer of the 12th Brigade at Soumagahara resulted in another prompt response from the co-located 12th Helicopter Unit. A total of nearly 50 personnel and a force of six helicopters had officially completed their mission soon after 15:00, around seven hours later.

The day after the mission in Kiryu, the 12th was called into what was to become a protracted six-day firefighting operation that involved 18 helicopters and around 530 personnel. Air support was provided by the Eastern Army Helicopter Squadron.

Feb. 15–23, 2014 / Response to Heavy Snowfall in Kanto Region

Over a nine-day period following excessive snowfall in the Kanto area, a total of around 5,000 JGSDF personnel, 1,000 vehicles and 130 aircraft were engaged in rescue, supply and snow-clearing operations.

Throughout this time, the 12th Helicopter Unit provided its airlift capabilities in support of operations in its home prefecture of Gunma as well as in Nagano and Yamanashi prefectures.

A total of 16 helicopters from the 12th Helicopter Unit and the 1st AvSqn, supported by around 110 personnel and 23 vehicles, were sent to deal with this blaze. The Ibaraki Prefecture governor having requested assistance via the local garrison in Katsuta at around 15:00 on March 25, the fire had been brought under control and the JGSDF units withdrawn down 24 hours later.

A fire having broken out in the vicinity of the Kurokawa Dam on the evening of April 15, the situation was already warranting JGSDF intervention the following morning. A combined force of 43 aircraft, from the 12th Helicopter Unit and 1st Transport Helicopter Group, took part in an operation that lasted until the early evening of April 19.

Just four days after the Hishimachi fire, the 12th was this time supported by the Eastern Army Aviation Group in another, thankfully lower key operation. The six helicopters and supporting units could be safely withdrawn at noon the following day.

Only briefly out of the woods, the 12th was back in action when another overnight operation was put in motion early in the afternoon of May 9.

A fire had broken out in the mountains close to the Sakai area of Okutama-machi, the westernmost town under Tokyo’s jurisdiction. Having received a request from the Tokyo governor, the commanding officer of the 1st Division in Nerima initiated a response that involved the 12th operating in concert with the Tachikawa-based 1st AvSqn and Eastern Army Aviation Group.

In all, 50 personnel, 10 vehicles and seven helicopters had been dispatched before operations could be safely wound down at 13:30 the following day.

The magnitude of this incident and the 20-day operation that followed warrant more than a cursory “snapshot.” Without warning, a massive eruption of this supposedly dormant volcano occurred shortly before noon on September 27, 2014. A popular destination for hikers and novice climbers, a combination of fine weather and the optimum time for viewing autumn colours fatefully ensured that several hundred people were present on the 3,076-metre peak at the time.

The first fatal eruption in Japan since 1991, when Nagasaki Prefecture’s Mount Unzen killed 43, including news media personnel and two volcanologists, the drama that unfolded here filled the news channels for days and weeks on end. Although, unlike Mount Unzen, there was no lava flow, the explosive mixture of steam, hot ash, rocks and gases claimed the lives of 63 people, five of whom have never been found.

Located 200km west of Tokyo and only 100km northeast of Nagoya, the mountain’s location at least facilitated a full-scale, rapid response, in which the 12th Helicopter Unit naturally played a significant role. The SDF air units that operated in concert with the 12th were the JGSDF’s 1st Transport Helicopter Group (Kisarazu) and Eastern Army Aviation Group (Tachikawa) as well as the JASDF’s Tactical Reconnaissance Group (Hyakuri), Air Rescue Wing (Komaki) at Hamamatsu Air Rescue Squadron.

As seen in the dramatic header photo of this section, the UH-60J was the helicopter of choice in the initial stages, the extraction of survivors and confirmation of fatalities. Although many had already made their own way down, around 40 people had spent that first night sheltering as best they could where they were on the mountain, the roof of a lodge having been destroyed by falling rock, and other buildings covered with ash.

A YouTube video (link) provides more of an idea of the conditions the helicopter crews and rescuers faced, but not of the smell of the high sulphur concentrations that forced back several rescue attempts. On that first day, UH-60J operations from the Nagano Prefecture side of the mountain alone resulted in the rescue of 21 people.

On September 29, those high levels of hydrogen sulphide gas emissions caused the complete suspension of operations. With dozens still stranded on the mountain, fears of another eruption amid escalating volcanic activity on September 30 prevented the active participation of a force of 850 rescuers, comprising Nagano and Gifu prefectural police and SDF personnel. Helicopters that had been about to airlift other rescue teams directly to the scene from Matsubara Sports Park in the village of Otaki, on the Nagano Prefecture side of the mountain, were grounded for the same reason.

ambulances would proceed smoothly.

The generally fine weather belied the fact that the daytime temperature at the peak was only around 5 deg C, dropping to below freezing at night. As the rescuers were to discover as the days passed, the flight to the peak was the easy part. Demanding conditions were created by the vast amounts of volcanic ash turning heavy and muddy when mixed with rain and becoming like cement when dry; there was also the ever-present risk of rain-induced mudslides.

Mount Ontake was still venting its anger on the afternoon of September 30, forcing the coordinating
Nagano Prefecture disaster relief authorities to suspend operations.

During the course of sombre operations on October 1, the death of 35 people was confirmed, and the sad task of airlifting their bodies to Matsubara Sports Park completed. From there, they were transported 20km by road to the former Ueda Elementary School in the town of Kiso.

Under normal conditions, the UH-60 manual recommends that prolonged rearward flight and downwind hovering be avoided to prevent the accumulation of exhaust fumes in the helicopter and heat damage to windows on open cargo doors. For this rescue operation, pilots and crews were subjected to noxious gases while maneuvering at or near the type’s high-altitude hovering limit. An undated photo in the December 2014 issue of Kōkū Fan magazine shows a UH-60JA after landing on the mountain, buried up to the top of its mainwheels in ash.

Another factor in the use of UH-60Js was the ability to quickly equip these aircraft with Inlet Particle Separator (IPS) units, filters to prevent the ingestion of volcanic ash into their engines. By October 2, at least one (105th Sqn, 1st Transport Helicopter Group) Chinook [link] was operating with its engine inlets covered by Engine Air Particle Separator (EAPS) filter devices. Although this equipment, purchased for possible overseas desert deployments, can reduce the available engine power, guarding the engines against overheating, turbine blade erosion and general corrosion is of more paramount importance.

Nature seemingly adding insult to injury, the approach of a typhoon brought operations to a halt once again on October 5–6. When the search resumed on October 7, there were still around 1,000 JGSDF, police and fire service personnel being brought in to take part in the search operation. That day, the bodies of more victims were brought down from the mountain to Matsubara Sports Park by CH-47.

Morning Photo Report, Part 1 (October 11, 2014)
A Gifu Prefecture-based Japanese blogger provided a two-part report on operations from the Matsubara Sports Park in Otaki, Nagano Prefecture. The mountain peaks were about due for their first snowfall, and thus he had wished to record some of the final efforts at searching for and recovering the bodies of the, at that time, eight still missing hikers and climbers. He took with him a case of nutritional drinks for the rescue teams and, if asked, just said he was from the news media, who were already in position for live broadcasts. Presumably previously earmarked for use in the event of somewhat lower key mountain rescue operations, three of the parks sports fields served as temporary heliports.

Taken when still dark at 05:30, the first aircraft images in Part 1 (link) record the arrival and departure, with the aid of the crew’s night vision goggles, of a UH-60J for the nearest main airport at Matsumoto. (The map shows the SDF field camp, which is normally a baseball field, at the top and the three heliports as well as, marked in red, the front-line HQ.)

Interspersed among photos of support vehicles are the arrival of a 12th Helicopter Unit UH-60J and distant shots of search teams being deposited on the mountain by Chinook, having likely flown in directly from Matsumoto airport. The first Chinook arrival at the sports field takes place just before 07:00, stopping only for 11 Nagano Prefecture police and 24 SDF members to file on board before departing.

The blogger quotes from a Kyodo News article published that evening. For the first time in three days, more victims had been found; the recovery of two more had brought the total number missing down to six. According to search party members, by this time helicopters were also being used to airlift drilling equipment to the summit to speed up the search process.

According to the Nagano Prefectural Disaster Response Headquarters, the searchable area near the summit amounted to around 26 hectares (64 acres), excluding the areas near the five craters and steep cliffs. The standard search had been completed on October 10, but the 550 people searching on October 11 had been tasked with just making sure nothing had been overlooked.

Morning Photo Report, Part 2 (October 15, 2014)
Compiled by the same blogger, Part 2 (link) records the comings and goings, between around 07:00 and 08:00, of mainly 12th Helicopter Unit CH-47Js; there are 104th Sqn, 1st Transport Helicopter Group CH-47JA interlopers at 7:21, 7:25, 7:47 and 7:54. The two-minute embedded video, recorded at the same sports park location on the windy morning of October 10, shows the arrival and departure of a 12th Helicopter Unit CH-47J on a day when three Chinooks were in operation.)

A YouTube video also exists of a 12th Helicopter Unit CH-47J at Matsumoto airport, also on October 15 (link).

In the end, due to snowfall and freezing conditions, the search for the bodies of the then six victims still unaccounted for had to be wound up on October 16. (See July 3–Aug. 7, 2015)

According a Japan Ministry of Defense press release dated October 16, 2014, over the course of the operation, the SDF provided around 600 of a total of 7,150 rescue personnel, 130 of 1,835 vehicles and 17 of 298 aircraft.

A six-minute video on the 20-day operation that the JGSDF uploaded to its YouTube channel provides a summary of the daunting task coupled with vivid images of the atrocious conditions under which the rescue and recovery phases were conducted. If nothing else, visitors to this website section should watch the sequence from 3:354:10, and not just for the aviation content.

The situation in this fire reached the stage where notices to prepare for evacuation were issued to residents living in the riverside districts of Okaya. Thankfully, in the end, the 16 helicopters from the 12th Helicopter Unit and Eastern Army Aviation Group sent in response managed to douse the fire and the impending disaster was averted.

The summer after the volcanic eruption tragedy, the 12th Helicopter Unit was back on a now tranquil Mt. Ontake as part of a resumption of efforts to recover the six missing victims the mountain had yet to surrender.

As he had been forced to call off the operation with the arrival of winter weather on the peak the previous October, the governor of Nagano Prefecture issued a request for a troop dispatch early in the evening of July 3. Bidding to bring the unfinished business to a successful conclusion, airlift support was again provided by the 12th Helicopter Unit, on this occasion accompanied by the Eastern Army Aviation Squadron. This mission involved not only the airlifting of the police and fire department search parties but also of the materiel, such as shelters, necessary to ensure their safety while in the area.

Viewable via YouTube (link), an Asahi Shimbun news video shot on July 25 shows a Chinook equipped with Engine Air Particle Separator (EAPS) filters landing next to the temporary shelters.

Having sent 1,160 personnel, 210 vehicles and 46 aircraft, all were withdrawn on the evening of August 7.

At 07:45 on September 10, 2015, a heavy rainfall warning was issued in Ibaraki Prefecture, and a major river, the Kinugawa, proceeded to burst its banks. As a result, at shortly after 09:00 the prefectural governor formally issued a request with the commanding officer of the JGSDF Engineer School in Katsuta for, initially, a rescue operation to be undertaken and flood prevention measures to be put in place.

Forming the focus of the subsequent intensive tri-service operations were the river cities of Joso and Yuki, which have populations of around 60,000 and 50,000, respectively.

Ground elements had actually been mobilized across the Kanto region since the early hours, but it was to be around 11:40 before four 12th Helicopter Unit UH-60Js became the first of 25 SDF aircraft to participate that day, in this case on SAR missions to assist anybody cut off by the floodwaters.

Viewable on YouTube (link), a short All-Nippon News Network (ANN) report includes dramatic video of one of the UH-60J crews plucking family members from their home, as a raging torrent threatens to sweep everything away. The footage was taken in Joso on that first day, September 10, 2015, following reports that there were around 100 people cut off in the Motoishige district of the city.

The 12th provided three UH-60Js the following day, but as the nature of the mission changed its only involvement thereafter was in the form of three OH-6Ds provided in support on September 14.

had struck Hokkaido was the airlift to the scene of personnel and equipment from, respectively, 
the SoftBank and KDDI mobile communications companies.

In scenes repeated at other JGSDF aviation centres during the month, the 12th made mainstream media and aviation magazine headlines early in March 2020 when a ceremony was held to mark the end of its association with the OH-6D. Centre stage for the events surrounding its final flight on March 6, 2020, 31313—the last of the 193 OH-6Ds Kawasaki built for the JGSDF—had notched up around 5,500 flight hours in a career spanning 23 years. Assigned to the HQ Flight of the 12th since 2001, the aircraft had seen service, for example, following the Chūetsu Earthquake of 2007 and during the Typhoon No. 19 relief operations in October 2019.

As recorded for posterity on a YouTube video (link), around 60 base personnel were present to see off the aircraft and its three-man crew, destination the OH-6D collection point at Kasumigaura Army Camp, Ibaraki Prefecture.

Mar. 2728, 2020 / Forest Firefighting, Kuji District, Ibaraki Prefecture

Two Chinooks from the 12th Helicopter Unit were called in for this brief operation, the location of which was roughly 135 km from Soumagahara.

The Ibaraki Prefecture governor’s request for assistance having been received at around 18:45 on March 27, two 1st AvSqn UH-1Js took off from Tachikawa, 150 km away, the following morning. After these TV camera-equipped aircraft had surveyed the scene, another UH-1J commenced firefighting operations at around 10:50. The two 12th Helicopter Unit Chinooks took over from around 13:15, and the operation was brought to a successful conclusion around 15:00.

(Above and below) Lest we forget, full-scale disaster relief operations in Japan involve a lot more
than JGSDF aviation unit aircraft and personnel. Taken at the rising and long after the going
down of the sun, these photos show rescuers during the relief operations in the city of
Joso, Ibaraki Prefecture, the area worst hit by the typhoon in September 2015.

12TH HELICOPTER UNIT MARKINGS

12th Helicopter Unit, 2nd Flight Markings/CH-47J

12th AvSqn(Photo [Sept. 2007]: Vantey via Wikimedia Commons)

A new unit marking (above) first appeared on tail rotor masts in August 2002. The design comprised a yellow eagle (ostensibly in flight but looking as if balancing) on a red katana (Japanese sword) with a white hilt. Extreme variations are used from time to time, such as this (link) seen at the Soumagahara base event held during the cherry blossom season in April 2008.

JGSDF 12th AvSqnThe normally yellow eagle and red sword were white and pink on a
12th Helicopter Unit aircraft at Tachikawa in November 2013.
 

Also in August 2002, the 2nd Flight adopted the kanji 武飛 (literally meaning “military flight,” the 武 being in a stylized form of red and yellow gradations), which appears low down aft of the cockpit doors.

12TH HELICOPTER UNIT SPECIAL MARKINGS

Every spring, the 12th Brigade has been in the habit of specially painting at least one of the 12th Helicopter Unit’s aircraft in a special scheme. The markings commemorate the brigade’s formation in 2001 and the establishment of a garrison at what was originally the tank base of Soumagahara in 1959. Following what were simple banners in the early years, cues have been taken from Japanese culture and the season of the year to “blossom” into more elaborate designs.

April 2005 (4th/46th anniversaries) CH-47JA 52966 / OH-6D 31313

The CH-47JA (link) sported a simple banner on each sponson and, as used in subsequent years, a slogan along the length of its upper fuselage access panel. The OH-6D (link), which was the last to have been delivered to the JGSDF, had the unit badge on its rotor mast and the wording 4thANNIVERSARY and 本部隊 (literally unit attached to HQ) on the cabin door.

April 2007 (6th/48th) CH-47JA 52967 / OH-6D 31313

Some idea of one 2007 design can be gained from these images. They were taken from an ad for a
Tomytec plastic model that could be finished in the markings of either the 2007 or the 2009 aircraft.

In addition to 6TH ANNIVERSARY along the upper fuselage access panel of the CH-47JA (link), artwork on the right sponson depicted 雷神 (raijin, the god of thunder seen in the photo above), that on the left 風神 (fūshin, the god of wind). Somewhat better images of these markings can be found in this event report (link).

2009 (8th/50th) CH-47JA 52957

Despite 2009 having been the base’s 50th anniversary, the thus far only usable image is again that
from a plastic model sales site that included the Tomytec box lid.

The inspiration for the design was that year’s long-running NHK TV historical drama called Tenchijin (Heaven, Earth and Man). The drama’s central character was Kanetsugu Naoe (1559–1620), a warlord who served the Uesugi samurai clan family during what is known as the Warring States period of Japanese history. He was selected as the 12th Brigade’s area of responsibility mainly covers the lands once owned by the Uesugi clan. The design on the left sponson featured an inscription as well as a helmet inscribed with the kanji 愛 (ai, love) and the Naoe family crest to the right of Naoe. On the right side was a silhouette map of Gunma Prefecture and cherry blossoms.

The tail emblem of the 2nd Flight, the 12th Brigade’s golden eagle clutching a Japanese sword, was also decorated with cherry blossoms.

2010 (9th/51st) CH-47JA 52966 (link) / OH-6D 31279 (link)

Using the by now standard practice, the Chinook’s upper fuselage access panel once again served as a billboard, on this occasion for the ‘9th Anniversary’.

On its left sponson (link) the Chinook featured a banner bearing the inscription ‘12th Brigade 9th Anniversary’, the brigade badge superimposed on a map on of Japan and some flames; the design on the bottom right of the banner is unclear. The banner on the right side (link) had a simple design of more flames and, as Gunma Prefecture is the leading producer of Daruma dolls, an image (with cherry blossom) of Darumataishi, the Japanese name for the Buddhist monk Bodhitharma, who lived in around the 5th century and on whom the doll talisman is based. The Japanese running along the top of the banner proudly proclaimed the 51st anniversary of Camp Soumagahara.

The right-side cockpit window (link) bore the names of the flight crew, and the coloured panel aft of the cockpit window the name of the maintenance crew chief assigned to the aircraft.

The OH-6D bore the 12th Brigade’s golden eagle marking on its rotor mast, as was the unit fashion back then, but its tail (link) had received some one-time-only artistic attention. To appeal to local residents in particular, this took the form of cherry blossoms falling like rain on one of the popular Daruma doll talismans. Note that the tail also sported two 12th Brigade eagle emblems in pink.

The public event originally planned for April 11, 2020, at which the aircraft prepared for the 19th/61st anniversaries would have been displayed, was cancelled exactly one month before to prevent the spread of coronavirus infections.

All JGSDF helicopter units give a small number of aircraft snow camouflage if and when engaged  
on winter training exercises. Although not special markings as such, J-HangarSpace likes to
assist in bringing great images chanced upon on Japanese Twitter, like this 12th Helicopter
Unit CH-47J, to a wider audience.

The local Gunma Prefecture newspaper, the Jomo Shimbun, recorded the first training flights of the year in January 2016 (link) and 2017 (link). For the former, a total of nine helicopters climbed to an altitude of about 1,000 metres, routed over the cities of Shibukawa, the prefectural capital Maebashi and Takasaki before returning to base around 45 minutes later.

Regional aviation group command was supplanted by direct ground (currently brigade-level) command in March 1994.

The 13th Aviation Squadron thus provides logistic support throughout the 13th Brigade’s area of operations. As shown on a page on the Brigade’s website (link), these cover the five most westerly prefectures on Honshu, from Tottori to Yamaguchi.

In March 2020, the website seemed to have undergone some changes. However, the latest information on the list of the unit’s disaster relief deployments (link [see below]), which dated from the formation of the Brigade in 1999, remained that for the Kumamoto Earthquake of April 2016, the magnitude of which prompted a response from outside Kyushu. A history page on the website that had offered a glimpse back more than 40 years, to river rescue training held in Wakayama and Hiroshima prefectures in 1978, seemed to have been removed.

Early in October 2019, the 13th AvSqn organized an air experience flight for local residents from
Kaitaichi Army Camp in Hiroshima Prefecture. The 15-minute flight gave the lucky lottery
winners contrasting bird’s-eye views of the areas damaged by the torrential rains in the
summer of 2018 and of the UNESCO World Heritage site at Miyajima.

The 13th having accepted delivery of its first OH-6D in March 1980, the type remained in service
for 40 years. Shown above, the last example operated was retired at the ceremony pictured below,
which was held at JASDF Hofu-Kita AB on March 19, 2020.

13th AvSqn Markings

Bearing the inscription 13th Aviation and the name of its crew chief (C/C Yoshihiko Iwomoto), this 13th AvSqn was a visitor to the Swell Festival event at JMSDF Ozuki in October 2014 (link).

The right side of the helicopter featured the addition of licence-builder Kawasaki Heavy Industries’ logo on the tail boom aft of the serial and, ornately written in white, the crew chief’s name underneath 13th Aviation. A cabin window inscription said 地域と共に (Together with the local community) and 第13飛行隊 (13th Squadron). The small white cross on the tail endplate is actually 十 (the number 10), which together with the three on the other side (see below) makes ‘13’.

(Photo: れんし[Renshi] via Twitter @Kirara21YA)

(Above and below) The left side was comparatively devoid of additional markings. The tail endplate sported 参 (san), which can mean the number three (in this case of ‘13’) and ‘participate’. Taken from the 13th Brigade’s badge, the three arrows on the rotor mast are a reference to the parable of the three arrows (being stronger than one) of Motonari Mōri (1497–1571), the feudal lord who unified what is now Japan’s Chugoku region. Written in white over the arrows, 百万一心 (hyakuman isshin, ‘one million, one heart’) conveys the notion of the unity of purpose of all those who serve or have served with the 13th Brigade. At a time when the making of a human sacrifice would have been the norm, Mori is said to instead have had the slogan carved into a stone of Koriyama Castle, in what is today Nara Prefecture, during its construction.

(Photo: れんし[Renshi] via Twitter @Kirara21YA)

The inscriptions seen in this head-on shot speak for themselves. With the exception of the unit and
crew chief name, all these markings had been removed by the time this aircraft was
displayed at Ozuki in October 2019.

Its formation stemming from that of the 14th Brigade under the 2nd Composite Brigade, the 14th AvSqn is the first JGSDF aviation unit to be permanently based on Shikoku; previously, the island had been provided with Central Army Aviation Group aircraft from Yao, Osaka Prefecture. It was there that a preparatory unit was formed within Central Army Aviation Group in March 2009.

JGSDF 14th AvSqn (2)The unit was involved in relief operations during the period of heavy snowfall Shikoku
suffered in December 2014.
(Photo: JGSDF/14th Brigade)

The unit’s first major disaster response operation came on August 30, 2010, five months after its formation. The 14th AvSqn was called upon to assist in evacuating residents and bringing under control a forest fire on Shodo Island on the Inland Sea.

The 14th AvSqn would be a contender for any future J-HangarSpace Best JGSDF Website award. Unlike most of its longer established sister units, the 14th AvSqn (or rather its parent 14th Brigade) makes full use of its website to provide news and show snapshots of life at the unit.

Its homepage (link) serving merely as a contents page, aviation content is primarily to be found on the Gallery page (link), which divides the current fiscal year (from April to March) by month. Images from previous years, which date back to those taken at the unit’s formation ceremony (link), are kept here (link).

Supporting a 14th Brigade ground deployment of 55 personnel and eight vehicles, the 14th AvSqn provided some of the reported 10 aircraft that dealt with a fire that broke out in the Kokubunji district of Takamatsu. The operation was initiated at lunchtime on January 9 and successfully completed around 24 hours later.

Formed from the disbanded 101st AvSqn (see below) on March 26, 2010, and trading in its last LR-1 (22019) for an LR-2 two months later, the 15th AvSqn was in existence for only three years, disbanding on March 25, 2013.

Within that time, the 15th AvSqn had increased the cumulative total of medical evacuation missions by 555 to 8,313 and the number of people airlifted in the course of those missions by 560 to 8,673.

The 15th is organized into an HQ Flight with two LR-2s (above) and the 1st Sqn (UH-60JA) and 2nd Sqn (CH-47JA).

The unit’s homepage (link) has four subpages. These provide an introduction to its roles/organization and aircraft as well as an overview of its medical evacuation (medevac) operations and a chronology that dates back to the beginnings of the 101st AvSqn in 1972 (see below).

The unit’s medevac area of responsibility covers all of Okinawa and Kagoshima Prefecture’s Amami archipelago, a distance of roughly 1,000 km east to west and 500 km north to south. As noted in the predecessor 101st AvSqn’s entry, two accidents in the course of these operations have sadly cost the lives of seven JGSDF service personnel and an accompanying doctor.

Maintained on the parent 15th Brigade homepage (link), a running total of the unit’s medical evacuation missions and the number of people airlifted in the course of those missions stood at 9,658 and 10,020, respectively, as at April 20, 2020. (The second line of figures records the current tally [386,060] and weight in tons [1.82] of unexploded shells from the war that the 15th Brigade has rendered harmless.)

15th Helicopter Unit Markings

Incorporating the Roman numeral for ‘15’, the 15th Helicopter Unit’s aircraft bear the alphanumeric code XVH.

The unit has retained the tail marking of its predecessor, the 15th AvSqn. In white, the marking combines a map of the main island of Okinawa with a crested serpent eagle that inhabits islands in Japan’s westernmost extremities.

The background of the full version of the unit marking (above) incorporates in yellow the family crest of the Ryukyu dynasty, to convey Okinawa’s origins as a separate empire, and the blue of the sea. Depicted in red is a local Naha landmark, the Shurei (Follow Courtesy) Gate, which also features on a 15th Brigade service medal.

In January 2017, one of the LR-2s was sporting a bird over Okinawa tail marking design (link).

A continuous thread running through the JGSDF presence on Okinawa has been its role in medical evacuation across the scattered islands of the island chain; the 101st recorded its first mission (to Aguni Island) on December 6, 1972, very soon after its formation. The 1,000th mission milestone was achieved on July 27, 1979, the 2,000th on November 28, 1984, and the 3,000th on October 7, 1989.

A low point in the unit’s history came on the 3,080th mission on February 17, 1990, when an LR-1 crew was tragically killed when their aircraft crashed into the sea off Miyako Island at night in poor weather conditions when arriving to collect a patient.

was replaced in March 2005.

Re-equipment in the form of the CH-47J—actually 52901, the first example the JGSDF had received in 1986—and UH-60JA (43107) came on February 7, 1996, and October 6, 1999, respectively. The last example of the KV-107 (51818), a type long associated with the 101st, left Okinawa on March 17, 1998; the UH-1H (41684) followed suit on November 26, 2002. The first LR-2 (23053) arrived on December 15, 2000.

A flight to Yoronjima in Kagoshima Prefecture on August 14, 1998, marked the accomplishment of the 5,000th medical evacuation mission.

In July 2000, the 101st was naturally involved in supporting the G8 Kyushu-Okinawa Summit.

During the approach phase on another medical evacuation operation, tragedy struck once again on the night of March 30, 2007, when the unit’s CH-47JA crashed on Mt. Amagi on Tokunoshima in Kagoshima Prefecture in poor weather conditions. Many local dignitaries paid their respects at the funeral service held for the four men who lost their lives on April 15.

The curtain came down on the 101st’s long-standing presence in Okinawa on March 25, 2010, when the 1st Composite Brigade disbanded. The 15th AvSqn assumed the mantle the following day.

At the end of its tenure, the 101st’s cumulative totals of medical evacuation missions and the number of people airlifted in the course of those missions had reached 7,758 and 8,113, respectively.

The Kisarazu-based 1st Transport Helicopter Group hosted an event to mark the end of an era on February 15, 2016, when the last LR-1 (22019) made its final flight. Up until May 20, 2008, the same aircraft had been the last of its type to be based with the 101st Aviation Squadron on Okinawa. Such was the aircraft’s close association, another aircraft was painted to masquerade as 22019 and be put on display.

Reporting directly to the 1st Helicopter Brigade rather than the 1st Transport Helicopter Group, the 102nd AvSqn newly formed in March 2008. The unit is charged with maintaining close cooperation with ground forces and would, if called upon, assume combat support roles, such as air mobility and reconnaissance.

March 6, 2020, saw the end of an era in 102nd Sqn history with the final departure, witnessed by
personnel from the parent 1st Helicopter Brigade, of the unit’s last OH-6D. Exactly 43 years had
passed since the arrival of the brigade’s first example in March 1977. Fittingly, a long-serving
102nd Sqn pilot was given the honour of being at the controls one last time to deliver the
aircraft from Kisarazu to Kasumigaura.

CH-47J KasumigauraA 105th Sqn pilot holds CH-47J 52915 at the hover at Kasumigaura in May 2014.

In 2014, 105th Sqn Capt. Masahiro Sakai wrote a short piece on the subject of aerial firefighting operations for the JGSDF website. The basic idea sounds simple: filling an underslung bucket with water from a nearby source, be it a lake, river or reservoir, even from the sea, and dropping the load at the scene of the fire. In reality, forest fires are not that easy to extinguish and, as will be noticed from the snapshots of operations included on these squadron history pages, tend to break out in Japan’s mountainous regions. Even after bombarding them with water from sunrise to sunset, on the ground and from the air, in the worst cases they can take days to bring under control.

Added to operating a Chinook with a six-tonne weight dangling beneath the aircraft in the turbulence of mountain passes, pilots and crew members have to concentrate for extended periods of time in a potentially dangerous environment. Major firefighting operations involve an orchestrated aerial ballet—in effect an aerial bucket brigade, but one in which they keep hold of their buckets—of helicopters from the JASDF, prefectural aviation units as well as the JGSDF, with news agency helicopters occasionally hovering on the periphery. Sakai also mentioned the added hazard of the many high-voltage lines around dams and forest fire sites and the extreme caution that has to be exercised when landing at or taking off from temporary bases where the unwieldy buckets are attached and the aircraft refueled.

105th Sqn Markings

The unit retains its predecessor’s marking that features the long-nosed goblin and famed swordsman Tengu, who is currently also gracing the tails of JASDF 304th Squadron F-15J/DJs. Coloured to signify the aircraft’s maintenance crew, a maple leaf appears behind Tengu’s red and black face, 105Avn to the right and the unit’s radio call-sign AKAGI in black below. (Tengu statues can be found on Mt. Akagi in Gunma Prefecture.) HGPV appears in black aft of the cockpit windows, the previous single yellow identification stripes having been removed from the nose and the front of the fuselage-side sponsons.

To fall into line with its sister units, the distinctive marking adopted by the predecessor unit—the head of a native American/American Indian with a black, white, red and yellow feather headdress in front of crossed arrows—was moved from either side of the nose to the tail rotor mast. The warrior still faces forward on both sides of the aircraft above the call-sign Kazusa; to the right is stencilled 106Avn. HGPVI appears in black aft of the cockpit windows, the previous double yellow identification stripes having been removed from the nose and the front of the fuselage-side sponsons.

Not generally overly given to decorating its aircraft for special occasions, the 1st Transport Helicopter Group’s 106th Sqn did take a leaf (or rather several cherry blossoms) from the “12th Helicopter Unit Special Marking Manual” in 2013. One of its Chinooks was decked out in a suitably high-visibility scheme to mark the Kazusa Flight’s 45th anniversary at that year’s Kisarazu open day event. Although only formed in 2008, the 106th can trace its ancestry back to the 1st Helicopter Brigade of 1968.

ANTI-TANK HELICOPTER (ATH) UNITS

1st ATH

Formed  March 25, 1986 (Obihiro)
Current Base  Obihiro

JGSDF 1stATH

The first of the five anti-tank helicopter units that formed at two-yearly intervals was deployed to the Northern Army region in 1986, when the major potential military threat was still a land invasion by the then Soviet Union. Each 18-aircraft unit was planned to comprise two (1st, 2nd) flights and an HQ Flight. In the case of the 1st ATH, the latter was also initially equipped with two OH-6Js, but the HQ flights of all five squadrons have since converted from the later OH-6D to the OH-1.

According to the unit’s single page on the Okadama Army Camp website (link), a 10-man office headed by a colonel was set up in March 1985, five months before a dedicated unit was established on site to oversee the preparations for the 1st ATH’s formation. The first AH-1S arrived in September 1985, the first OH-6J in February 1986.

The installation of an AH-1 simulator was completed at Obihiro in March 1989. The 1st ATH utilized live-fire training facilities in the United States during joint exercises at the Pohakuloa Training Area in Hawaii (November 1992) and at the Yakima Training Center in the state of Washington (September 1998, September 2006). The unit’s turns to participate at the SDF live-fire demonstrations at the Fuji training area came in August 2000 and August 2005.

More recently, the unit was involved in missile launch training with JGSDF AH-64 Apaches in May 2012 and sent to the United States for training again two months later.

Having accepted delivery of its first OH-1 (the 14th built) in November 2002, the construction of a dedicated OH-1 hangar was completed in February 2004. The unit’s OH-1s were involved in the practice firing of an air-to-air missile based on the Type 91 portable anti-aircraft missile in September 2012.

A series of photos taken on March 12, 2016, when the unit held a ceremony to mark its 30th anniversary can be found here (link). That January, one of the AH-1Ss had been painted in winter camouflage (see photo below), a practice that had reportedly not been seen since 2011. (A photo from way back in January 1997 [link] shows a 1st ATH OH-6D in snow camouflage.)

In October 2017, the website still featured a group of photos recording AH-1S training in the United States in July 2014 and a launch of the air-to-air missile from an OH-1 in September the same year.

The 1st ATH provided reconnaissance support during relief operations in the aftermath of the Mt. Usu eruption in Hokkaido Prefecture in April 2000 and provided support for the G8 summit held at Lake Toya, also in Hokkaido Prefecture, in July 2008.

2nd ATH

Formed  March 25, 1988 (Hachinohe)
Current Base Hachinohe 

Lacking its own homepage and with no detailed information on its Hachinohe Army Camp base page, this unit seems to be unusually media shy. (Unlike other JGSDF units, only two of the five ATH units, the 1st and the 3rd, have some form of web page, and even these provide only basic information that is not updated.)

A search of Japanese Google in October 2017 unearthed only one reference, dated July 2014, when the Aomori Prefectural Government requested to know what had led to a rubber seal falling off an aircraft in flight and also that measures be taken to prevent a recurrence. When time permits, J-HangarSpace will add any information found in the aviation press, for example a JWings report, albeit from mid-2006, on the unit’s OH-1 operations.

In the meantime, a selection of photos from Japanese aviation websites that feature aircraft from this “mystery” unit.

One site offers a collection of photos, posted during the course of 2017, of 2nd ATH AH-1S aircraft during displays at JASDF Matsushima in August 2006 and at the JMSDF Hachinohe base open days in September 2006 and September 2009 (link).

The same site contains images (link) of 2nd ATH OH-1s that were present at the JGSDF Kita-Utsunomiya air show in May 2006, the same JMSDF Hachinohe event in 2006 as well as in 2007. One shot at the latter (link) shows the 21st and last OH-1 built, hence the ‘Omega 621’ on the nose. Below the kanji 祝 (iwai, meaning ‘congratulations’), the Japanese written under the cockpit reads ‘2007 Hachinohe Air Base Show’. The marking beneath the main rotor is too difficult to identify.

All taken at Kasuminome, the first photo from another site (link) shows one of two 2nd ATH aircraft that, along with an OH-1, debuted in winter camouflage in January 2010. Taken a month later, in February 2010, the second photo (link) shows the second aircraft from the right-hand side, its garish camouflage looking incongruous and hardly effective against the backdrop formed by the city of Sendai.

JGSDF helicopters often sport unit badges and, on occasion, nose art. Comprising a missile-straddling mascot, wearing a helmet equipped with a sight and bamboo dragonfly toy-like rotor, this example (link) was seen on a 2nd ATH Unit AH-1S at JASDF Misawa in September 2003.

3rd ATH

Formed March 26, 1990 (Metabaru) 
Current Base Metabaru 

According to the unit’s subsequently removed website page, an office to oversee the formation of what was to become the 3rd ATH Unit was set up on March 24, 1989. The office was upgraded to unit status in preparation for squadron formation on August 11 that year, exactly a week after the completion of an AH-1 hangar. The squadron inauguration formalities took place on March 26, 1990.

On June 6, 1991, the unit was sent to assist in the disaster relief operations following the eruption of Mt. Unzen/Fugendake in Nagasaki Prefecture.

The installation of an AH-1 simulator at Metabaru was completed on October 14, 1993, and live-fire training conducted in the United States in September of each of 1994, 2000 and 2002 as well as in August 2007. The 3rd ATH made its debut at the Fuji live-fire demonstration in August 1995.

Having received its first OH-1 on February 9, 2006, the unit was declared at full strength with four aircraft on February 15, 2008; a hangar to house the OH-1s had been completed on April 5, 2006. An AH-64 first joined the ranks in 2009, the year before the unit’s 20th anniversary. Four photos taken on the day of the anniversary, March 13, 2010, can be found here (link).

3rd ATH Unit Markings

Like its sister units, 3rd ATH aircraft an identification alphanumeric code, in this case IIIATH.

Seen in the previous photo link, an AH-1S was painted in a suitably serpentine marking on the occasion of the unit’s 20th anniversary in 2010 (link).

The previous year, a similar but winged serpent design had been adopted by the 3rd ATH for the 48th anniversary of the Western Region Army (link), wording to that effect appearing on a plaque, framed by the snake’s tail, on both sides of the engine. It was presumably the same aircraft that was present at the Air Memorial event at JMSDF Kanoya in May 2009.

An OH-6D assigned to the 3rd ATH was at the JASDF Nyutabaru air show in November 1993 (link).

4th ATH

Formed  March 27, 1992 (Kisarazu)
Current Base Kisarazu 

Assigned to the Eastern Region Army upon its formation in March 1992, the 4th ATH notched up its 25th anniversary as a Kisarazu resident in 2017. Despite being assigned to the capital region, this unit has no dedicated web page.

A photo report in Japan Self-Defense Force Squadron (sic) (Ikaros Publications, Summer 1996), showed elements of the unit during two weeks of training at the U.S. Army’s Yakima Training Center in the state of Washington in November 1994, when three AH-1Ss and one of the unit’s two OH-6Ds were deployed.

At the time of the Kisarazu visit to gather material for JSDF Squadron in late April 1996, the 2nd Sqn was away on deployment training, leaving the 1st Sqn to man the fort. The report covered a training mission by the three-aircraft 1st Flight, which at that time was commanded by a Major Hiratsuka, at 35 already referred to as a veteran pilot.

The report describes, from the pre-flight briefing, a standard six-hour training mission, involving heading south and following the Tanba Highway for a refueling stop at Takigahara Army Camp in Shizuoka Prefecture before undertaking training at the North Fuji Maneuver Area. Night training was taken on the return flight to Kisarazu, where the aircraft landed at 21:00.

The head of the flight section who had given the pre-flight briefing, Major Nakamura said that, aside from its combat training, the squadron had assumed responsibilities for post-disaster reconnaissance missions since the Great Hanshin-Awaji Earthquake of January 1995. In the event of an earthquake in the Tokyo metropolitan area, 4th ATHS aircraft would be rapidly launched on damage assessment and information gathering missions.

Helicopters are regularly used for PR and recruitment purposes at events held at JGSDF garrisons. Filmed in April 2017, YouTube footage (link) records the arrival and setting up for static display of a 4th ATH Unit AH-1S at Shibata Army Camp, Niigata Prefecture, which was marking the 62nd anniversary of its establishment.

Like its sister units, the 4th ATH carries an identification alphanumeric code, IVATH. The 1st Flight and HQ Flight are devoid of other identifying marks, but 2nd Flight aircraft have a short white diagonal stripe beneath their rotor masts.

An OH-6D of the 4th ATH Unit’s HQ Flight, which is now equipped with the OH-1, was at Gifu for overhaul in October 1997 (link).

For the Kisarazu air show in late October 2011, when the nation was still recovering from the effects of the Great East Japan Earthquake the previous March, a 4th ATH AH-1S (link) was painted in a design that mixed a sharkmouth with an anime character, cherry blossoms and a slogan of encouragement in assisting those in the tsunami-affected areas: With One Heart, Let’s Do Our Best Japan! The names of the unit’s eight crew chiefs were listed on the sides of the engine cowlings.

The OH-1 on display that day (link) had a more subdued design comprising a ninja, the aircraft’s unofficial and ill-suited nickname—the noise of its engine hardly enables a stealthy approach—and the Japanese for ‘Kisarazu Air Show 2011’ in black on the nose.

In 2004, the Akeno open day was confined to indoor displays due to a passing typhoon. The following day, aircraft that had been “confined to barracks” were pulled out from their hangars in the fine weather that usually follows. The aircraft included an AH-1S with a fuselage-length white snake marking, bearing the words MA AVIATION 50th Anniversary, MA referring to the founding of the “middle army” (officially the Central Region Army) of the JGSDF (link).

Dating back to the NSF’s short-lived Northern District organization, what had become the JGSDF’s Northern Army Aviation Corps on July 1, 1954, was reformed into the Northern Army Aviation Squadron on January 18, 1962. The unit then incorporated three former NSF/JGSDF District Aviation Corps as hikōtai (aviation squadrons) —the 2nd (at Asahikawa), 5th (Obihiro) and 7th (Okadama)—plus the newly formed 11th at Kita-Chitose and the Northern Army Aviation Squadron itself at Okadama. An aviation corps that had been attached to an artillery brigade was disbanded at that time.

The formation of the Northern Army Helicopter Squadron on March 1, 1968, was followed by that of the 1st Anti-Tank Helicopter Unit at Obihiro on March 25, 1986.

In early 1980, the Northern Army’s own aviation squadron was operating a mixed-bag fleet of LR-1s, LMs and L-19s alongside OH-6Js.  On March 28, 1994, all four aviation squadrons were passed to division-level command, and the Northern Army’s own aviation squadron disbanded. However, its OH-6 flight was incorporated into the Northern Army Helicopter Squadron, while its LR-1 remained for operation by the newly re-designated Northern Army HQ Flight. The organization in overall command was designated the Northern Army Aviation Group.

Snapshots of Northern Army Aviation Squadron Operations

A page on the Northern Army’s website (link) provides details of selected operations. The earliest coverage of a major disaster relief operation is that following the earthquake that occurred off the coast of southwest Hokkaido in July 1993.

A major earthquake that struck off the southwest coast of Hokkaido at 22:17 on July 12, 1993, triggered a tsunami that in a matter of minutes had devastated vast tracts of the island town of Okushiri.

Northern Army utility helicopter elements were naturally the first to answer the calls for assistance. The mission included the airlifting of troops to the scene at dawn on July 13 and then shuttling back and forth to bring in 100 troops from the garrison in Kutchan, close to the Niseko ski resort area, to help with firefighting and casualty evacuations as well as searches for missing persons. While an operational coordination center was set up at Okushiri’s town hall, the next wave saw another 110 JGSDF personnel airlifted direct to a disaster-affected district of the town. About 30 minutes away by air from Hakodate, Okushiri’s airport was used as a forward medical centre with both civilian and military hospital staff flown in actually from the JGSDF Makomanai garrison in Sapporo.

A dark day in this unit’s history came on May 15, 2017. Contact with an LR-2 was lost when the crew were making preparations for an instrument approach into Hakodate airport on a mission to pick up an emergency hospital case, strong winds and rain as well as thunder and even fog advisories having ruled out a helicopter operation. The wreckage of the aircraft was found the following morning in a mountain forest near Hokuto, around 30 km northwest of Hakodate; all four on board had perished. As reported in the September 14, 2017, edition of the Mainichi Shimbun, the accident investigation findings attributed the initial cause to the pilot having inadvertently disengaged the autopilot while talking to air traffic control, exacerbated by a loss of special awareness.

The wholesale reorganization of the JGSDF that took place January 18, 1962, resulted in the Kasuminome-based 6th District’s 6th Aviation Corps being joined by the 9th from Hachinohe and re-designated hikōtai (aviation squadrons) under the command of the newly formed Northeastern Army Aviation Group. The Northeastern Army Aviation Squadron was also newly formed on that day.

The Northeastern Army Helicopter Squadron came into being on March 1, 1968, also at Kasuminome, but moved to Jinmachi Army Camp (Yamagata Airport) on March 6, 1969. 

Taken in July 1975, this photo (link) of a Northeastern Army Aviation Squadron OH-6J parked in front of the Kasuminome tower has a nice tranquil feel; you can almost hear the twittering of the birds. Come early 1980, and the Northeastern Army’s own squadron was operating the LR-1, L-19, LM and OH-6Js, while the helicopter component was flying UH-1Bs and ’Hs, all from that same airfield. The 2nd Anti-Tank Helicopter Unit formed at Hachinohe on March 25, 1988.

On March 28, 1994, the two aviation squadrons were passed to division-level command, and the fixed-wing element of the Northeastern Army Aviation Squadron reformed as the Northeastern Army HQ Flight.

Eastern (E)

Formed Jan. 18, 1962 (Kasumigaura) 
Current Base (Eastern Army HQ Flight) Tachikawa 

On January 18, 1962, the Kasumigaura-based 1st District reorganized its 1st Aviation Corps into the 1st Aviation Squadron under the Eastern Army Aviation Group. In this case, the co-located newly formed sister unit was designated the 12th Aviation Squadron, which was newly formed with the Eastern Army Aviation Squadron.

Only around 10 months were to pass before the Eastern Army Aviation Group’s HQ was relocated to Kita-Utsunomiya.

Back at Kasumigaura, the Eastern Army Helicopter Squadron was newly formed on August 1, 1969.

It was the regional entity’s turn to move in 1972, an advance guard that formed at Tachikawa in Tokyo on March 7 being joined by the main force on December 27 of that year; the HQ moved from Kita-Utsunomiya on May 3, 1973.

The region’s 4th Anti-Tank Helicopter Unit joined the ranks at Kisarazu on March 27, 1992. On March 28, 1994, the 1st and 12th aviation squadrons were passed to division-level command, and the fixed-wing element of the Eastern Army Aviation Squadron reformed as the Eastern Army HQ Flight.

According to its Japanese-language website (link), the geographical extent of the Eastern Army’s defense and disaster relief responsibilities encompasses the Tokyo metropolitan area, the 10 prefectures of the Kanto and Koshin’etsu regions (including Sado Island off the coast of Niigata Prefecture) plus Shizuoka Prefecture. The land area covered amounts to around 70,800 sq. km, or nearly 20% of Japan’s total land mass, and its 51.7 million inhabitants represent 40% of Japan’s total population and also 40% of the nation’s gross domestic product. The Sea of Japan and Pacific Ocean coastlines extend for 600km and 1,600km, respectively.

The Tokyo Metropolitan Government-administered area, and with it the Eastern Army’s remit, also includes no less than 481 islands in the Pacific Ocean, 16 of which are inhabited. The latter extend from Izu-Oshima (a mere 100km away to the south), the Ogasawara (Bonin) Island chain (1,000km) and Iwo To (formerly Iwo Jima, 1,200km) to Japan’s most easterly point, Minami-torishima (the Marcus Islands atoll, 1,848km away to the southeast). The latter is actually home to a Self-Defense Force and Japan Coast Guard presence, including a runway that can accept supply flights made by JASDF, JMSDF and JCG transport aircraft.

JGSDF Central Army AvGrpThe JGSDF has historically always referred to its Central Army as its Middle Army, hence MA Aviation Group appears on the badge shown on the unit’s website (link). 

Formed on January 18, 1962, the Central Region Aviation Group comprised the existing 3rd District’s 3rd Aviation Corps at Yao and the 10th District’s 10th Aviation Corps at Akeno, which were made into aviation squadrons. Newly formed on that day were the 13th Aviation Squadron, which moved from Yao to Hofu in November that year, and the Central Army Aviation Squadron.

The Central Army Helicopter Squadron was newly formed on March 1, 1968.

On March 28, 1994, the 3rd and 10th and 13th aviation squadrons were passed to division-level command, and the fixed-wing element of the Central Army Aviation Squadron reformed as the Central Army HQ Flight. The region’s 5th Anti-Tank Helicopter Unit became the last of its kind to form at that time and was declared fully operational in June that year.

JGSDF Central Army AvGrp HQ SqnThe wording on the unit’s badge says “Middle Army Aviation Group HQ Unit”  

In March 2006, operation of the Central Army HQ Flight’s LR-1 was transferred to what was now termed the Liaison/Reconnaissance Flight.

Three years later, in March 2009, a unit charged with preparing for the formation of the 14th Aviation Squadron was set up within the HQ organization; the process was declared complete on March 26, 2010, when the 14th officially joined the ranks under the command of the 14th Division.

The next major re-equipment process, of supplying the Central Army Aviation Squadron with OH-1s, was commenced on February 16 and completed on March 27, 2012.

In 2014, the unit’s 16 aircraft were called upon to assist when major landslides struck parts of the city of Hiroshima in August and during the heavy snowfall in Tokushima Prefecture in December as well as to relay images taken from the air in the aftermath of natural disasters.

Professionally filmed at Yao by SankeiNews on January 13, 2015, this short YouTube video (link) shows the Central Army Aviation Group’s first flight of the year.

Having already been formed at Ozuki on January 1, 1956, the Western Army Aviation Group moved to the JGSDF’s Takumabaru Army Camp (the location of today’s Kumamoto Airport) on August 20, 1957.

On January 18, 1962, the local JGSDF aviation elements in western Japan followed the example of the other regions by forming aviation squadrons, the 4th from the existing 4th District’s 4th Aviation Corps alongside the newly formed 8th, both at Metabaru. Also newly formed at Metabaru was the Western Army Aviation Squadron.

During the course of 1971, the 8th Aviation Squadron and the Western Army Aviation Squadron moved from Metabaru to Takayubaru.

(*) A long-term resident of Oita City, aviation photographer Takao Kadokami has kindly made a large number of his photos available to J-HangarSpace. Living in Kyushu meant that he was well placed to capture on camera many of the aviation events in that part of Japan, including the comings and goings of JGSDF Western Region aircraft at Oita Airport. One of his earliest photos, a November 1955 image of a school friend standing in front of a JGSDF L-5A Sentinel at Oita, graces this website’s homepage.

On March 28, 1994, the 4th and 8th aviation squadrons were passed to division-level command, and the fixed-wing element of the Western Army Aviation Squadron reformed as the Western Army HQ Flight.

In other rotorcraft developments, the Western Army Helicopter Squadron was newly formed on March 1, 1968, the region’s 3rd Anti-Tank Helicopter Unit on March 26, 1990. Initially equipped with the AH-1S, the latter was also supplied with its first AH-64 on March 12, 2010.

Spanning the years 1959 to 1977, the following is a chronological selection of more photos from Takao Kadokami’s archives.

Current Base Okadama 

Having formed on March 1, 1968, the Northern Region Helicopter Squadron supported the 1972 Winter Olympics in Sapporo.

On March 28, 1994, the Northern Army’s own aviation squadron disbanded and its OH-6 flight was incorporated into the Northern Army Helicopter Squadron, which came under the command of the Northern Army Aviation Group. The unit surpassed the 51,000 accident-free hours mark in 1996.

Aside from regular training exercises covering every eventuality, domestic disaster relief operations have included the 1993 Hokkaido earthquake and the volcanic eruption of Mt. Usu, Hokkaido Prefecture, in 2000. Overseas, the unit was part of the international earthquake relief operations in Pakistan in 2005 and, in contrast, took part in live-fire missile training in the United States in 2006.

In terms of equipment, the first of the then new OH-6Ds was received in 1994, the first OH-1 in 2011. The unusual sight of one of the Northern Army Helicopter Squadron OH-6Ds fitted with twin loudspeakers was recorded at Okadama in September 2005 (link).

Other photos can be found on the unit’s dedicated page on the Okadama Army Camp website (link). These include a UH-1J close to the Mt. Usu volcano in 2000 and two images of the relief operations in Pakistan in 2005.

Snapshots of Northern Army Helicopter Squadron Operations

February 10–17, 1996 / Toyohama Tunnel Disaster

Involving elements from the Northern Army Aviation Group in response operations, a major disaster of a different kind occurred early in 1996.

At around 08:00 on February 10 that year, a rock fall caused a huge boulder to strike a roadway entrance to the Toyohama Tunnel, near the town of Furubira, Hokkaido Prefecture; 20 lives were lost. In freezing conditions, blasting the rock to enable rescue operations was successful only on the fourth attempt. Those operations involved 3,400 JGSDF troops, 760 vehicles and 60 helicopters.

During this four-month period, it was the Hokkaido-based 11th Brigade’s turn to be the JGSDF unit on standby to respond to international calls for assistance at the behest of the Japan International Cooperation Agency (JICA). As one of the brigade’s component air units in such a situation, the Northern Army Aviation Group was sent in support of Japan Disaster Relief Team efforts following the August 1999 Izmit Earthquake in Turkey.

Although not the most exciting of insights into JGSDF helicopter operations, this does serve to show another dimension, namely preparation for disaster relief.

One of the first tasks after an event has occurred is to rapidly set up on-the-spot or nearby communications links. As a result of the lessons learned from the Niigata Chuetsu Offshore Earthquake of 2004, the government had contracted the first of two communications providers in 2007, and this was the third time that this training had been conducted in Hokkaido.

In this case partnered with the 11th AvSqn and local, prefectural-level firefighting units, NH crews dealt with, unusually, consecutive blazes in the Ofunecho district of Hakodate (April 25–26) and near the town of Shiriuchi (April 26–28). During the former operation, a combined total of 8.1 tonnes of water were released in 12 drops, during the latter 19.6 tonnes in 28 drops.

The port city of Tomakomai, located in the Iburi district south of Sapporo, bore the brunt of this major earthquake, which struck at 03:08 on September 6, 2018. Felt in the Kanto region far to the south, the earthquake claimed 41 lives, caused widespread damage and left 5.3 million inhabitants without power. The Northern Army Helicopter Squadron was heavily involved from the outset, initially in the rescue and damage assessment phases and later in support of ground units in the airlift of supplies and materiel to the disaster-affected areas.

May 28–30, 2019 / Forest Firefighting, Omu, Hokkaido Prefecture

The Northern Army Air Squadron’s involvement in this operation (also covered in the 2nd AvSqn entry in JGSDF Squadron Histories Part 1) started in the early hours of May 28, the day after the outbreak of the fire.

Continuing the water-bombing initiated by the 2nd AvSqn on the afternoon of the first day, a single UH-1J departed Okadama at around 06:45 on the next three days, and a video-camera equipped UH-1J at 10:35 on May 29 and 06:28 on May 30. These operations were dovetailed with those not only of the 2nd AvSqn but also the 1st Helicopter Brigade at Kisarazu and the JASDF’s Misawa-based Helicopter Airlift Squadron.

Pilot Profile

A Northeastern Army Helicopter Squadron pilot was interviewed as one of a series of SDF profiles that appeared on The Sankei News website in October 2019. Major Masayuki Baba (54) started by saying that there was an awareness of mission in your readiness as an officer that he had heard being spoken of by those around him since he had joined the JGSDF. He then joked that he had finally reached the point of understanding what that really meant after a military career that had spanned 35 years.

A native of Fukushima Prefecture, his devotion to the sport of kendo had stayed with him from his elementary to his high school days. The discipline and physical training aspects of the JGSDF had thus appealed and after enlisting had led him to qualify as a pilot in 1989. He had naturally taken part in many a mission that had been fraught with danger.

On March 11, 2011, the day of the Great East Japan Earthquake, he had been on leave to attend his eldest son’s junior high school graduation ceremony. He had hurried back to report for duty at Kasuminome, Sendai being very much on the disaster’s front line. That evening saw him at the controls of a UH-1J, heading for the Arahama Elementary School, where many people had sought refuge on the roof. On the way, he noticed people in dire need of assistance on the roof of their home, and thought that was more pressing than the school, where many helicopters would be in attendance. Having received clearance, he had rushed to the family’s assistance. Etched in his memory is the expression and voice of an old lady he helped to rescue who, when asked if anyone else were in need of help, had said “They’re already dead.”

Baba is now very clearly aware of the mission assigned to him: to pass on his experience and lessons to be learned from the rescue operations at that time to subsequent generations of helicopter pilots.

On September 25, 2019, an Eastern Army Helicopter Sqn UH-1J was called upon to once again
put the camera equipment to use. On this occasion, a two-day search was conducted around the
village of Doshi, Yamanashi Prefecture, where a person was still missing after Typhoon No. 15.

October 2019 / Typhoon No. 19

Following the 19th typhoon, which passed though in October 2019, elements of the Eastern Region Helicopter Sqn were sent on a disaster relief operation to Nagano Prefecture. Initially, four UH-1Js conducted reconnaissance and rescue operations along part of the Chikuma River on October 13. Out of the six helicopters involved the following day, two were equipped to relay images from the scene in real time. A total of 38 people were airlifted to safety during the course of this operation alone. 

Equipped to relay images from the scenes of natural disasters, an Eastern Army Helicopter Sqn

Designed to assist in maintaining and improving the squadron’s level of training based on the results of daily evaluations, manoeuvres were conducted at the Soumagahara and Fuji exercise areas, in Gunma and Shizuoka prefectures, respectively. This was the second major training exercise in fiscal year 2019, which ended on March 31. Held over seven days from mid-September 2019, the previous training had also featured the 4th Anti-Tank Helicopter Squadron and thus involved the coordination of the Eastern Region Aviation Group as a whole. In addition to Soumagahara the training had been carried out at the Sekiyama exercise area in Niigata Prefecture.

Special Transport
Helicopter Sqn (STH)

Formed (As Dedicated Government Helicopter Sqn) Sept. 1985
(As Special Transport Helicopter Sqn) Dec. 1986 
Current Base Kisarazu 

Placed under the command of the 1st Helicopter Brigade, the Special Transport Helicopter Squadron (Tokubetsu Yusō Herikoputa Hikōtai) received its first of three AS332Ls in December 1986. All these were placed in storage at Kasumigaseki following the service entry of three EC-225LPs in March 2006; it was to be 11 years before buyers were successfully found for two of them.

JGSDF AS332L over JDATwo Aérospatiale AS332L Super Pumas overfly what was then the Japan Defense Agency (left, now the
Ministry of Defense) circa 2001. Three aircraft of this type were acquired for the Special Transport
Helicopter Squadron in 1986 and placed in store after their withdrawal from use in 2006.
Two departed to join the fleet of an operator in New Zealand early in 2018.
(Photo: Japan Ministry of Defense)

Upon the formation of the 1st Transport Helicopter Group in place of the unit’s former parent 1st Helicopter Brigade on March 28, 2008, the special transport unit’s English designation remained the same, but in Japanese was changed from hikōtai to tai.

JGSDF EC225LP H225 TachikawaAn Airbus Helicopters H225 Super Puma at Tachikawa in November 2013. Carrying the unit code STH
instead of ST, three of the then Eurocopter EC225LPs replaced the AS332Ls during the course of 2006.

JGSDF logo EC225LP H225
The JGSDF symbol and English motto (above) have been applied to both sides of the current Super Puma aircraft. Depicting a stylized map of Japan being held in cupped hands, the design more closely matches the Japanese version of the motto, which expresses the desire of JGSDF personnel to protect and, should it ever be necessary, defend the country. According to the official Japanese explanation of the design on the Ministry of Defense website (link), the left hand expresses “robustness and strength”, the right “benevolence”. The design is slanted forward by 10 degrees to instill a “sense of movement and symbolize the forward-looking advances Japan is making”.

September 2019. After Typhoon No. 15 had caused significant damage in parts of Chiba Prefecture,
Defense Minister Taro Kono was flown by Special Transport Helicopter Sqn Puma to JMSDF
Tateyama. From there he travelled to the disaster-affected city of Kimitsu to observe at 
first-hand the relief operations then under way.

MAIN AVIATION SCHOOL/BRANCH SCHOOLS (UNIT CODES)

Main Aviation School, Akeno (S)
The Hōantai Aviation School that formed at Hamamatsu on October 15, 1952, became the JGSDF’s Aviation School on July 1, 1954. Training operations were commenced from Akeno in August 1955, following the relocation of the training units from Hamamatsu.

JGSDF L-21B OitaHaving originally been operated by the National Security Force in the 1950s, an L-21B bearing the S marking of the Main Aviation School was part of a Self-Defense Force exhibition held in Oita City in 1968. (Photo: Takao Kadokami)

Placed under Main Aviation School control, an Air Training Support Squadron formed at Akeno on March 25, 1977, and has subsequently operated from both Akeno and the Fuji live-firing range.

Iwanuma Branch School
Located in Sendai, Miyagi Prefecture, the Iwanuma Branch School formed on August 1, 1964 for fixed-wing aircraft pilot training and closed on March 19, 1973.

JGSDF LR-1 UtsunomiyaAn LR-1 at Utsunomiya in May 1984 displays a low-visibility colour scheme applied for experimental
purposes only. Not surprisingly featuring a matt instead of the previous gloss finish as well as black
rather than white markings, the size of national markings was reduced and
dayglo areas removed.

JGSDF TH-55J UtsunomiyaObtained direct from Hughes, the TH-55J was the JGSDF’s basic rotary-wing training workhorse from
1972 to 1995. Seen at Utsunomiya in May 1984, this example continues to provide training as an
instructional airframe at the Japan Aviation Academy’s Wajima Noto Airport Campus
in Ishikawa Prefecture.

JGSDF UH-1B UtsunomiyaStrongly influenced by the U.S. Army’s airborne cavalry concept and operations in the Vietnam conflict,
the JGSDF received 90 Fuji-built UH-1Bs between 1962 and 1971 and bestowed on them the unofficial
name Hiyodori; this pair of “bulbuls” were native to Utsunomiya in May 1984. The aircraft in the
background was last seen, in a somewhat derelict state, at a
tonkatsu (pork cutlet) restaurant in
Ogawamachi, Ibaraki Prefecture, in 2004.

fixed-wing pilot training in 1981 and passed on to their initially intended recipient in
the early 1990s. (Photo: Akira Watanabe)

JGSDF Sky Hornets team (1)(Photo: Akira Watanabe)

The above photo shows the JGSDF Sky Hornets display team performing at Utsunomiya in May 1981.

Formed in 1974 and made up of instructor pilots, the team initially flew four OH-6Js but by the end had long since transitioned onto the OH-6D and was choreographing five-aircraft routines and, unlike the Blue Impulse, using coloured smoke. In addition to its Utsunomiya home base, the team also participated at Kasumigaura and Tachikawa events.

A 10-minute YouTube video exists of their 2012 performance at Utsunomiya (link). J-HangarSpace was present for the 2013 display (below), which comprised two displays interspersed by a rest and refuelling break.

Featuring a box art photo by Hajime Ishihara, plastic model maker Hasegawa marked the end of an era by bringing out a limited edition kit (above) of the specially adorned aircraft that was on static display that day. 

JGSDF OH-6D special marking

To end with the commemorative marking theme, an OH-6D had been painted and placed on display (above) to commemorate the 40th anniversary of JGSDF Kita-Utsunomiya in May 2013.

JGSDF Training Helicopter Cavalcade

Former JGSDF H-13H KirishimaFormer JGSDF H-13H (Kawasaki-Bell 47G-2) 30124 ended its days at the Dai-ichi Institute of
Technology in Kirishima, Kagoshima Prefecture. First delivered in December 1959, its flying
career at the Akeno Main Aviation School had ceased in October 1973.

JGSDF H-13KH AkenoOn the baking hot apron at Akeno in August 1977, a maintenance crew member appears to be receiving some ground engine run tuition on an H-13KH (Kawasaki-Bell 47G-3B/KH-4). 30201 was the first of a total of 19 of this variant operated by the JGSDF. In service at the very start of the JGSDF in July 1954, the H-13 soldiered on until 1982. (Photo: Takao Kadokami)

JGSDF TH-55J AkenoAlso present at Akeno that same hot day in August 1977 was TH-55J 61328. A total of 38 aircraft of
this type were delivered from 1971 to 1975 for use at all JGSDF helicopter training bases; the last
was withdrawn from service in the mid-1990s. This example is now in the storage hangar at the
Tokorozawa Aviation Museum, Saitama Prefecture, where it is given an annual public airing.
(Photo: Takao Kadokami)

JGSDF OH-6J AkenoAkeno was naturally home to a number of OH-6Js, the type selected to replace the H-13 and L-19 and to
be the JGSDF’s standard observation helicopter; a total of 117 were delivered between 1969 and 1977.
Training examples sported high-visibility orange tails and in some cases, as here, orange
fuselage undersides. 
(Photo [August 1977]: Takao Kadokami)

JGSDF TH-480B UtsunomiyaThe sun glinting off the top of its fuselage like navigation lights, a shiny new TH-480B lifts off from
Utsunomiya in May 2013. Hastening the end of OH-6D training in the JGSDF, manufacturer
Enstrom delivered the last 28 of the total of 30 TH-480B helicopters in double-quick
time over three years in response to a Defense Ministry concentrated procurement
programme. The last entered service early in 2015.

At the Akeno Army Camp 60th anniversary event in 2015 event was this based TH-480B. The artwork aft 
of the cockpit depicts the sacred Meoto Iwa
(Married Couple Rocks) that are located just off the
shore at Futami, Mie Prefecture, and over which the sun rises in summer.

 JGSDF AH-1S YokotaThe first of two U.S.-built AH-1S helicopters on display at Yokota AB in July 1982. These aircraft were
to U.S. Army AH-1E standard, identified by the upward-pointing exhaust, while the 90 built under
licence by Fuji were equivalent to the AH-1F and have rearward-facing exhausts. Delivered in
June 1979, this aircraft is now on display at the JGSDF Public Information Center at
Asaka, Saitama Prefecture.

In October 2016, it was the turn of an Aviation School-assigned OH-1 (see photo above) to be displayed in special markings, on this occasion for JGSDF Akeno Army Camp’s 61st anniversary. The main elements of the design were: a large white nose marking that featured the kanji 忍 (nin) from ninja in combination with a large shuriken, the weapon more popularly known as a ninja star; a red-and-white disc on the rear fuselage, actually a rebus that decodes into the kanji for Akeno (明野), the well-known design that formed the tail code crest of the wartime Akeno Army Fighter School; and, on the tail, a silhouette map of Mie Prefecture and three rotors signifying the three JGSDF training schools (at Takigahara, Utsunomiya and Kasumigaura) located outside the prefecture.

TRAINING SUPPORT FLIGHTS (SD)

Each of two locations, Akeno and Takigahara, houses a Training Support Flight. These have their origins in the Air Training Support Squadron that was formed at Akeno under Main Aviation School command on March 25, 1977.
