Obu airport (おおぶひこうじょう) is the airport that was ever in the district extending over Obu-shi, Aichi and Tokai-shi. Another name, Chita airport.

It unfolded in the north side whole area of the current Chita Peninsula road Tokai, Obu interchange.

Airport start of construction by Mitsubishi Heavy Industries

The Mitsubishi Heavy Industries Nagoya plane Seisakujo (existing: Nagoya aerospace system mill) where I won fame by many plane production to assume a fighter a representative in 0 sets of warships established the production base in the Oe factory of Nagoya-shi for a long time ([1] that the head office of) was established for the Mitsubishi plane (second generation until December, 2014).

分載 did the body which I made in Oe factory on a cow carriage, a carriage, a truck and relied on the transportation of the production machine by Mitsubishi for the method that was irrationality with the inefficiency that I carried to Kagamigaharahikojo of Gifu in those days. In the case of a two-engined plane, I pulled the body in two cows. I made the frames, and the main wing of right and left leaned it against a cart, and a cow pulled it with by one. I divided the tail assemblies into two with a frame and pulled each at one horse. The engine and the attached parts progressed by two trucks. Therefore, four cows in total, two horses, two trucks were necessary to carry one plane. In addition, I needed 48km to Kakamigahara for 24 hours because the way was small and was rough and went by stages. Above all, what turned at a cow carriage and the carriage on the small road between Komaki and Inuyama was not easy and I took off a cow, a horse and lifted a cart with human power and changed a direction. I crouched down with a person, a cow, the horse until wind was relieved and couldn't but wait without pushing it forward forward on one day of the wind because the main wing raised it and carried it [2].

The setting of the assembly plant belonging to a runway was pressed the neighborhood for to cancel this even slightly early [3]. It is from October (1941) for 1,941 years that Obumachi, Chita-gun and Mitsubishi Heavy Industries Nagoya plane Seisakujo at the time came to have close relations. Mitsubishi acquires the land of approximately 5,700,000 tsubos (19 square kilometers) (1941) in the hilly areas extending over Obumachi and adjacent Uenomachi, Chita-gun (existing Tokai-shi) on October 15 in 1941 and holds a groundbreaking ceremony as "Chita airport and Chita factory" on 17th [3]. It depended greatly on the trouble of the town assembly including Mayor Sakai at the time for the purchase of this land [4].

I sharpened the heap of Chita hill countries and was large-scale construction to fill the valley. I employed various groups, the municipalities service groups of Chita-gun, Aichi-gun, the blue sea county, a Chinese captive in construction and prepared land with several thousand with a scoop, a unicycle, a straw-basket every day, but advanced only slowly [5]. In addition, some rewards wanted to be taken out, and there was it with [6] for service provided through physical labor from the military authority and did not seem to be really free labor.

Airport completion and evacuation of Mitsubishi

Summary of an airport, the factory

I started work, and an airport was finally completed (1944) on April 6 in 1944 30 months later. The Obu airport made good results through a long-time dream for Mitsubishi. The first taking off and landing test was carried out by 99 sets of carrier-borne bombers and two planes of Mitsubishi MC-20 which came flying from Kagamigaharahikojo and succeeded wonderfully [3]. The machine tool which amounted to 3,800 was provided for 660,000 square meters of buildings in total, and the finished airport was called "Mitsubishi plane Chita factory" [3] or "Mitsubishi fifth mill" [4] or "Mitsubishi plane Chita repair shop" [2].

It was the last factory that the Chita factory collected the main parts of the airplane made in a factory of each place and assembled and test-piloted it and had a role to deliver to the military [3]. The engine was carried by a motor mill of Daikou, Higashi-ku-cho, Nagoya-shi, and the main wing part and the body, the tail assembly part transported it with a truck by rail from Oecho, Minato-ku, Nagoya-shi and Okazaki, a factory of Ichinomiya [2].

After the autumn of 1944, a measuring line for exclusive use of Mitsubishi was laid from Japanese National Railways Obu Station, and the import of the parts with the railroad was enabled. Exclusive measuring line orbit extension 3,337m. Cost of construction 735,000 yen. The approach to the airport became the switchback method for a steep grade [4].

 
100 sets of headquarters spy plane three type (キ 46-III, RAF Museum).

The line of the assembly plant always assembled around ten planes by an assembly line in two of them, but was Mitsubishi MC-20 and 100 sets of headquarters spy planes first.

 
Four sets of heavy bomber one type (キ 67-I)

Four sets of heavy bombers (an enlightened emperor or enlightened emperor) came to occupy the line soon. It was 2 degrees to have broken through 60 monthly productions while the war situation admitted of no delay, but, as for the test pilot, three people were the only one including the plant manager (additional post). If there was the airplane which got off with one test, there were five times and the thing which you must test-pilot and was full of the pressure four times [2].

 
The runway trace (I make it based on Ministry of Land, Infrastructure and Transport country image information (color aerial photo) of 1982) of the Nakajima airplane solder mill. Nakaumacho, Handa-shi, the neighborhood of Nakaokudacho. A runway is in the lower right direction from photograph leaning to the left.

As for the scale of the airport, 1,300m in length, 60m in width, the instruction course were 1,000m in length, 30m in width the main runway. The East-West supporting runways were planned particularly, too, but were not able to come true at the end of the war [4]. A northwest edge swelled out in a circle, and the main runway made the shape such as the matchstick. The Nakajima airplane solder mill which there was in the neighborhood, the Kiyosu airport of the army adopted a similar shape.

It was not very an airport hard to please except that I was strong in wind in winter [2].

I jumped out of Obu airport, and, according to the memory of the plant manager, the った four sets heavy bomber often transported it by air in the back mountains of Kameyama-shi, Mie. I was calling it Fukai swamp and was the secret airport with the runway of the cross approximately 1,000m in length. Four sets of heavy bombers were covered by the pine wood whether it was the part of the airplane preservation plan that I prepared for mainland decisive battle as soon as they landed [2]. This secret airport is regarded as Oiwake airport (located in the due north of the current east Meihan Expressway Expressway Suzuka Interchange.an aerial photograph of the neighborhood of Oiwake airport at the time of 1947.the source: Geographical Survey Institute map, aerial photo reading service) that was in Suzuka-shi, Mie by a position and the form of the airport.

In addition, there are documents [7] "which were careless before I let you take off from the finished product" from this Obu airport, but the truth does not know it.

Evacuation of Mitsubishi

By the southeast sea earthquake that shook our district suddenly (1944) on December 7 in 1944, in the Mitsubishi Heavy Industries Nagoya plane Oe factory, facility, an assembling jig were damaged by a big crack in the ground, and the factory fell into paralysis. In addition, the nerve center of the factory caught the crushing blow not to mention human damage by bombing of B29 on the same month 18, and evacuation began in a hurry in Obumachi at the time [4].

We had the airport that, as a result, was just completed and a united feeling in the evacuation place.

I was divided into けとして, the block of the Western airport area of Japanese National Railways Tokaido Main Line, the chancre mountainous district ward of the east side of Tokaido Main Line for the block of the evacuation place. Approximately 60 wooden buildings are built as a building and are almost completed (1945) in start of construction, August of the year in March in 1945. A main building around Obu Station was used as a management section. Obumachi government office the second floor, a hospital, a personal residence, public hall (as personnel department), the House of guardian deity of children (as education section). In addition, in front of Obu Station, Obu dormitory, facilities section, materials section, a work plan, general affairs department, the Security Research Division, an Operations Section, Transport Sections formed a line [4], and, in Obu, there were a town of Mitsubishi and the feeling that it was suddenly.

Purchase place of 飛行場直接以外 [4]

  1. On December 1, 1943, it is 13,120 square meters for the Obu Station north side packing.
  2. In June, 1944, a freight home for exclusive use of Mitsubishi is new in Obu Station.
  3. On June 1, 1944, I acquire 177,984 square meters of Suzuki violin factory traces as an Oiwake factory office and warehouse place.
  4. On October 1, 1944, I acquire 43,884 square meters as exclusive petition measuring line sites from Obu Station to the airports. It becomes the lead-in for exclusive use of Mitsubishi.
  5. In May, 1945, I acquire 2,059 square meters as Mitsubishi Hospital site in Obumachi.
  6. On June 26, 1945, I acquire 25,705 square meters as Obu station square site.

The end of the war and postwar

End of the war

It is August 15 (1945) for 1,945 years. Four sets of heavy bomber "enlightened emperors" of several stayed in the Obu airport. The vigor until yesterday disappeared, and anyone was taken by despondency. It occurred to the plant manager to fly an airplane. The Allied Forces has not been yet stationed. "The enlightened emperor" with people who lent the power to a police officer and a member of firefighting team, the making of airport nearby flew the sky of Chita for ten days before a flight ban order appearing from the Allied Forces headquarters [2].

October begins (1945) 1945, and is immediate; the Allied Forces headquarters of the airplane give it an order to start incinerating it. The parts were crushed in a big hatchet, and, by the hand of the worker, gasoline was sprinkled in the completion body and was incinerated [2]; [3].

The plane production in the Obu airport will tell the end here, too.

Central part Japan newspaper publisher and Toyoda Automatic Loom Works

Part of the airport was switched to the farm of the agriculture pioneer after the war, but the remaining land was left as possession of Mitsubishi Heavy Industries. (an aerial photograph of the neighborhood of Obu airport at the time of 1948.the source: Geographical Survey Institute map, aerial photo reading service)

 
Toyota Industries Corp. long grass factory

It was February (1952) in 1952, and Toyoda Automatic Loom Works (Toyota Industries Corp. in the back) purchased the district where assembly plants were concentrated through the good offices of Obumachi. I used it as the examination room of the agricultural machine, a finished vehicle place for APA emergency demand vehicle in the company, but it was the 40, Showa generation and became the production of pub Rika vans base as a long grass factory [8]. The long grass factory continues producing starlet Vitz afterwards.

Similarly (1952), central part Japan newspaper publisher (Chunichi Shimbunsha in the back) established "middle day Obu airport" on June 1 in 1952. According to the newspaper publisher, it was advertised with civil airport first in those days. It was 230,000 square meters in area, runway long 450m [9].

I only sounded the corner of the original Obu airport even if I vomited and was said to be a runway if more terrible than Rabaul base, but, in the airport where still was independent in those days, there was only here [2].

I started from amphibious plane "enlightened emperor" (Republic アビエーション RC3 type sea bar) and two planes of "white dove" (Piper aircraft PA20) given the name same as "the enlightened emperor" who had been ever produced in Obu airport on August 15, the same year.

Three bell aircraft 47D types-passenger helicopter arrives at the Obu airport (1952) in November in 1952. The plane was left later in 川崎重工 and bought a role for a technical investigation for domestic production helicopter first development.

The accident that a company airplane "enlightened emperor" crashes into the runway east side embankment (1953) on the middle day in February in 1953, and two crews become seriously injured is outbreak.

The Obu airport is closed down (1958) on the middle day in July in 1958. The middle day machine moved to Nagoya Airport [9].

 
The road which traces a former runway trace. Nippon Steel Sumikin company house or Circle K of the U.S. form a line in the roadside

The former runway trace made a city area it around the company house of Nippon Steel Nagoya ironworks (existing: Nippon Steel Sumikin Nagoya ironworks) after (1958) in 1958 [7]. In addition, I have lost that there was ever an airport here only by the high shelf of the Chita Peninsula road extending over a runway trace, and having had a look. The neighborhood of road is lined with MINISTOP and Circle K of the U.S., Valor, Seven-Eleven. Part of runway trace became the road, but the width largely decreases. The flat topography will show that it was an airport alone unnaturally for a hill country.

 
The road where it is thought that there was Mitsubishi exclusive railway once. The neighborhood of Obu-shi udo intersection.

In addition, an exclusive measuring line is laid from Obu Station, and the sign has ever remained in the airport clearly until the about 1970s, but becoming it becomes remarkable, and a part seems to remain as a road, but the trace is full of it, and a city area becomes incomprehensible afterwards.
