The Nakajima Aircraft Company was a prominent Japanese producer of aircraft and aviation engines during World War II. This enterprise eventually transformed into the automotive and aerospace manufacturer known today as Subaru.
History
Established in 1918 by naval engineer Chikuhei Nakajima alongside textile entrepreneur Seibei Kawanishi under the original name , it holds the distinction of being Japan's pioneering aircraft manufacturer. After the founders parted ways in 1919, Nakajima took control of the factory with backing from the Imperial Japanese Army, renaming it Nakajima Aircraft Company.
Primary production sites included:
- Tokyo facility
- Musashino facility
- Donryu facility
- Ota facility, located near Ōta Station, which Emperor Shōwa visited in 1934; this site suffered damage from American air raids in 1945 and currently serves as a Subaru Corporation kei truck manufacturing plant.
- Koizumi facility, close to Nishi-Koizumi station, also targeted in 1945 bombings, now operated by Sanyo.
After World War II
In the aftermath of Japan’s surrender, the Supreme Commander for the Allied Powers prohibited aircraft manufacturing, compelling Nakajima to halt its operations. Unlike rival firm Mitsubishi Heavy Industries, Nakajima had not expanded beyond aviation and consequently fragmented into several spin-offs led by former managers and engineers. These professionals played a crucial role in revitalizing Japan’s automotive sector after the war.
The company reestablished itself in 1953 as Fuji Heavy Industries, initiating production of Fuji Rabbit scooters and Subaru cars. Fuji Precision Industries—later known as Prince Motor Company—also emerged from Nakajima’s heritage, producing vehicles such as the Prince Skyline before merging with Nissan in 1966. Fuji resumed aircraft manufacturing during the mid-1950s, supplying trainers and helicopters for the Japan Self-Defense Forces. In 2017, Fuji Heavy Industries adopted the Subaru Corporation name.
