was a Japanese aircraft manufacturer focused on producing planes primarily for the Imperial Japanese Army Air Force. Its headquarters were located in Tachikawa, within Tokyo Prefecture.

Tachikawa Aircraft

The company originated in November 1924 when Ishikawajima Shipyards (which later became IHI Corporation) founded the . Its inaugural model was a basic trainer known as the Red Dragonfly.

By 1936, the Imperial Japanese Army had acquired a majority stake, leading to its renaming as Tachikawa Aircraft Company Ltd. The firm mainly manufactured training and fighter aircraft for the Army, including indigenous designs such as the Ki-9 and Ki-36. Additionally, it developed limited production variants and experimental aircraft like the Ki-77.

In 1940, Tachikawa secured licensing rights to produce the Lockheed Model 14 Super Electra, which it built under the designation Army Type LO transport. The company also assembled aircraft conceived by other Japanese manufacturers.

Operations ended following Japan’s surrender in August 1945. The company’s facilities suffered extensive damage due to wartime air raids, and its assets—including the airfield—were confiscated by U.S. forces and converted into Tachikawa Air Base. Numerous engineers shifted careers into the automotive sector, joining firms such as Nissan and Toyota, thereby aiding Japan’s automotive industry expansion. The Prince Motor Company, later absorbed by Nissan, was directly derived from Tachikawa Aircraft.

New Tachikawa Aircraft Company

Post-World War II, Japan’s aviation industry was dismantled during the Allied occupation. Once restrictions on aircraft development were lifted in November 1949, Tachikawa Aircraft was reformed as the .

During the early 1950s, Shin Tachikawa designed prototype trainers including the R-52 and R-53, with the R-52 recognized as the first all-Japanese aircraft produced after the war. Neither model achieved market success; consequently, the company maintained its business by manufacturing precision parts for aviation and other sectors. In 1955, it adopted a new name to signify its withdrawal from aircraft manufacturing. Beginning in 1976, after reclaiming land formerly held by the United States Air Force, the enterprise diversified into fields such as real estate development, consumer electronics, and automotive components production.
