# Nakajima Aircraft Company

The Nakajima Aircraft Company (中島飛行機株式会社, Nakajima Hikōki Kabushiki Kaisha) was a prominent Japanese aircraft manufacturer and aviation engine manufacturer throughout World War II. It continues as the car and aircraft manufacturer Subaru.

## History

The Nakajima Aircraft company was Japan's first aircraft manufacturer, and was founded in 1918 by Chikuhei Nakajima, a naval engineer, and Seibei Kawanishi, a textile manufacturer, as Nihon Hikoki (Nippon Aircraft). In 1919, the two founders split and Nakajima bought out Nihon Aircraft's factory with tacit help from the Imperial Japanese Army. The company was renamed Nakajima Aircraft Company in 1919.
The company's manufacturing facilities were:
* Tokyo plant
* Musashino plant
* Donryu plant
* Ota plant, near Ōta Station. Visited by Emperor Shōwa on November 16, 1934. Critically damaged by American bombardment on February 10, 1945. Currently a Subaru Corporation plant for kei trucks.
* Koizumi plant, near Nishi-Koizumi station. Critically damaged by American bombardment on April 3, 1945. Currently a Sanyo plant.

## After World War II

After Japan's defeat in World War II, the company was forced to close, as the production and research of aircraft was prohibited by the Supreme Commander for the Allied Powers. This had a severe impact on Nakajima as one of the two largest aircraft manufacturers in Japan; the second was Mitsubishi Heavy Industries (MHI). Unlike MHI, Nakajima did not diversify into shipbuilding and general machinery, and so was forced to dissolve into a number of spin-off companies set up by its former managers, engineers, and workers. As a result, leading aeronautical engineers from the company, such as Ryoichi Nakagawa, helped transform Japan's automobile industry.
The company was reborn in 1953 as Fuji Heavy Industries, maker of Fuji Rabbit scooters and Subaru automobiles, and as Fuji Precision Industries (later renamed Prince Motor Company, which merged with Nissan in August 1966), manufacturer of Prince Skyline and Prince Gloria automobiles. Fuji began aircraft production in the mid-1950s and produced military training aircraft and helicopters for the Japan Self-Defense Forces. In 2017, it rebranded as Subaru Corporation.
