The company manufactured a number of types, mostly training aircraft and fighters for the Imperial Japanese Army.
In 1940, the company received license-production rights to the Lockheed Model 14 Super Electra which it produced as the Army Type LO transport.
As with all Japanese manufacturers, production of all types ceased after the surrender of Japan to Allied forces in August 1945.
Many of its engineers went to work for Nissan and Toyota, helping develop the technologies of the Japanese automobile industry.
Since 1976, after the return of a large amount of land occupied by the United States Air Force since the end of World War II, the company turned towards real estate development, consumer electronics, and the production of automotive parts.
