The Go-To Website for
Information on Japanese Aviation

A pair of Kawasaki T-4s from the 13th Flight Training Wing based at Ashiya AB, Fukuoka Prefecture, in
December 2016. One sporting a two-tone grey scheme is joined by a sister aircraft specially painted
for the base air show in October and bearing the slogan 1000 T-4 student pilots graduated to mark a
major unit milestone. The upper fuselage wording was changed from ASHIYA AIR SHOW 2016 to
ASHIYA AIR BASE 2017 for the aircraft’s appearances at displays in December.

J-HangarSpace first slid open its doors on June 1, 2013, and the site already houses a wealth of detailed information on a wide range of Japanese aviation topics.

As you will notice from the navigation buttons to the left, the site is primarily devoted to subject matter from the 1950s onwards. Each section features, or will feature, information culled largely from Japanese-language sources, much of which will be appearing in English for the first time. Although some civil aviation topics are included, hangar space is at a premium and thus none is given over to airline operations.

JASDF 60th anninversary logo

Mindful that Japan’s three Self-Defence Forces commemorated their 60th anniversary in 2014, some emphasis is being placed on their formative years. Each SDF section contains a Where Are They Now? guide, providing information on and selected photos from the locations of surviving examples of withdrawn aircraft. A Where Are They Now? Guide by Prefecture is included at the end of the JMSDF page.

(Above and below) Around 60 years ago, the supply of U.S. aircraft to the three SDF services was in full swing. These photos were taken at Tateyama, Chiba Prefecture, on February 12, 1955, when a ceremony was held to mark the official handover of 10 Grumman TBM-3W2 Avengers and 12 North American SNJs to the nascent JMSDF. The event was covered by Sekai no Kōkūki (The World’s Aircraft), a
monthly magazine that had been launched in 1951 but sadly was to cease publication in 1957.

A rare photo of  a JGSDF Stinson L-5A Sentinel. Assigned to the 4th District Air Unit at Ozuki, Yamaguchi Prefecture, this example was noted at Oita airfield, Oita Prefecture, on November 1, 1955, in the days when security was not a high priority. The JGSDF inherited a motley collection of around 
35 L-5s in four variants from the National Police Reserve, but all had been retired by 1958.

Each service has a page devoted to updates on its current aircraft programmes and projects. One click will ultimately also take site visitors from the homepage to squadron histories and markings or base histories, the latter including contact information. Planned for inclusion over the longer term are aircraft profiles that will focus on the design, development, and operation (including pilot perspectives) of selected indigenous types utilized by these services over the years.

As the Japan Coast Guard (JCG) has been more in the news of late, I will be building on the of necessity brief information I included some years ago in an article that appeared the UK magazine Air International. Again, the early days of JCG air operations are worthy of closer scrutiny.

Hardly surprisingly, the air operations of the Japanese prefectural police have received scant coverage overseas. The same can be said of the so-called parapublic operations conducted by fire and disaster prevention air units at the municipal and prefectural levels and the Doctor-Heli emergency medical services (EMS) network; further down the road (in my spare time!), I will be seeking to use this site to redress the balance.

Historical content has thus far spotlighted Japan’s aviation museums, particularly those that have little or no English-language content. One aim here is to provide translations of exhibit information to make museum tours by overseas visitors that much more rewarding.

As time passes, I hope to be adding more regular news reports to the Bulletin Board started in 2016 that now has a dedicated page. Other exciting site features will be revealed nearer the time.

This is still very much a work in progress, so please bear with me while I continue to add meatier content to the “bare bones” of some sections. An overview of J-HangarSpace operations can be found at the foot of this page.

Thanks for your visit and keep watching this space!

Japan’s Newest Aviation Museum Visited

J-HangarSpace finally manages to find the time to file its latest roving report, from the new aviation museum at JGSDF Kisarazu Army Camp, Chiba Prefecture (link), which was officially opened on February 25, 2017. The collection’s KV-107II-4A is featured in the third Displayed Aircraft Special Report that follows the JGSDF Where Are They Now? section (link). 

Shown above, The Nakajima Type 91 at the Tokorozawa Aviation Museum (TAM), Saitama Prefecture, is historically important for two reasons: as the sole survivor of the around 450 that were produced in two versions and as an example of one of the few Japanese-produced aircraft of the 1930s aircraft that remains in the same condition now as it was then.

For the second feature on its Japanese Aviation History (to 1945) page (link), J-HangarSpace focuses on the work of the little-known Japan Aeronautic Association (JAA) Aviation Heritage Archive and some of the aircraft, from the TAM Type 91 to the Misawa Aviation & Science Museum Tachikawa Ki-54 (below), that have received certification under the JAA’s Important Aviation Heritage Asset programme.

New Book Time 2017

Covering a current JASDF aircraft type from a markedly different angle (of attack), this book charts the project to return to operational service F-2Bs damaged by the March 2011 tsunami. (A review can be found on the Magazines/Books page here link.)

The latest addition to the section devoted to reviews of English-language books on Japanese aviation history topics is this important April release from Stratus/MMP.

New releases from Japanese aviation publishers have been few and far between of late, but this February 2017 offering from DaiNippon Kaiga was well worth the wait. You can find a review in the Japanese Language/Historical section on the Magazines/Books page.

While I Was Away in 2015

Every year, work enforces periods of absence from the hangar. During that time in 2015, I was happy to once again assist Japanese aviation historian Kōji Yanagisawa in telling the story of two intrepid aviators who flew a Japanese-designed biplane from Tokyo to Rome in 1931. Aptly enough, the article appears in Issue 14 of The Aviation Historian. A superbly designed and executed quarterly magazine for the discerning reader of more offbeat topics, TAH more than lives up to the wording trumpeted on the cover: The modern journal of classic aeroplanes and the history of flying.

A banner link to the TAH website appears in the right-hand Notices column of this homepage.

During the course of 2015, J-HangarSpace compiled a roundup of site-relevant content carried in the major Japanese aviation magazines. In 2017, selected titles will be added to the existing “e-cupboard” of book reviews. These two sections are separated by access information for the Japan Aeronautic Association (JAA) library in Tokyo. Visitors’ attention is also drawn to the Bookstall carousel of recommended reading at the foot of this homepage.

Kindly provided by well-known aviation photographer and historian William T. “Bill” Larkins, this shot shows a lineup of factory-fresh, JASDF-bound Beech T-34A Mentors at Oakland Airport, California, in October 1954. A view from another angle, on the Early SDF History chronology page,
 reveals a surprising fact about these aircraft.
(A true aviation photography veteran, Bill Larkins has photographed for posterity thousands of aircraft that have graced the skies, airfields and airports of his native California. [link])

Continuing the theme of the previous report, J-HangarSpace took a tour of Tokyo Heliport on a sunny February afternoon to bring you Location Report 9. Visits to three of the resident operators provided a rare look behind the scenes and offer visitors to J-HangarSpace a taste of the reports and features to come on the pages covering the Police Aviation Units, Fire/Disaster Prevention and the Doctor-Heli Network.

Many passengers travelling on the Tokyo Monorail that connects Tokyo International
(Haneda) Airport with the city’s Hamamatsucho Station will have caught sight of an
unassuming hangar close to Seibijo (‘maintenance area’) Station emblazoned with
the name Japan Coast Guard above the doors. Thanks to a fortunate chain of
events, J-HangarSpace was recently able to join a 15-strong group that was
granted a tour of the facility for Location Report 8. 

Every August, the Zero Fighter Museum (Kawaguchiko Aviation Hall) in Yamanashi Prefecture offers the general public a time-limited chance to check on the status of its restoration projects and other treasures. J-HangarSpace’s report focuses on the collection’s unique restored/reverse-engineered fuselage of
a Mitsubishi G4M2 Betty bomber. 

Of all the displays at the JGSDF Public Information Center at Kasumigaura Army Camp in Ibaraki Prefecture, perhaps the most fascinating are those covering its time as an Imperial Japanese Naval Air Force (IJNAF) base.
The June 2014 addition to the Aviation Museum page reveals more. 

Marking a slight departure from the normal coverage, the May 2014 Location Report 7 had J-HangarSpace joining a group tour of the Ministry of Defense compound in Tokyo.

Location Report 6 was from the 2014 Spring Festival at the U.S. Naval Air Facility (NAF) Atsugi. There J-HangarSpace was able to photograph Kawasaki P-1
patrol aircraft on the ground and, an added bonus, in the air. 

Part air show report, part museum visit, J-HangarSpace’s fifth Location Report came from the annual Cherry Blossom Festival at Kumagaya AB in Saitama Prefecture.

In February 2014, the museum collection at Mitsubishi Heavy Industries’ Komaki South Plant became the fifth to be visited by J-HangarSpace. Among the gems on display are a restored J8M1 Shusui interceptor and A6M5 Zero Type 52 fighter.
(Note: This facility has been closed since June 2017 pending refurbishment/relocation.)

Recognize this engine? J-HangarSpace’s fourth aviation museum report came from the
collection entrusted to Mitsu Seiki Co., Ltd., a company that has carved itself several
niches in the precision engineering industry from its base in Awaji, Hyogo Prefecture.

One of the JMSDF’s two remaining ShinMaywa US-1A rescue amphibians returned to its birthplace for the last time in February 2014. J-HangarSpace was present to witness two days of test flying that involved takeoffs and landings at sea
for Location Report 4.

To mark the 60th anniversary of Japan’s Self-Defense Forces, J-HangarSpace conducted a census of retired SDF aircraft. See the end of the JGSDF Where Are They Now? page for details of two early results from the census.

J-HangarSpace’s last feature of 2013 covered a special exhibition at the well-known Tokyo home of a Mitsubishi Zero fighter, the National Museum of Nature and Science in Ueno Park. Part of the Japan Aeronautic Association’s centenary celebrations, the exhibition showcased some fascinating memorabilia and evocative images from bygone eras of Japanese civil aviation.

This JMSDF ShinMaywa US-1A rescue amphibian was one of 50 aircraft that took part in the flypast at the 2013 SDF Review ceremony. See Location Report 3
for more details.

The October 2013 addition to the aviation museum section involved a visit to the Subaru service centre that has a Fuji T-1B as its very own gate guard.

Kumazo Hino steps out of Yoshitoshi Tokugawa’s shadow in J-HangarSpace’s debut Japanese aviation history topic (here). The article reports from the monument to the
two men instrumental in sowing the seeds of Japanese aviation development by
being the first to fly heavier-than-air machines in the country.
