Japan's first aircraft manufacturer, it was founded in 1918 by a naval engineer, Chikuhei Nakajima, and a textile manufacturer, Seibei Kawanishi 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.
Nakajima Aircraft Company's manufacturing facilities consisted of the following:
Ota plant, near Ōta Station. Visited by Emperor Hirohito on November 16, 1934. Critically damaged by American bombardment on February 10, 1945. Currently a Fuji Heavy Industries plant.
After Japan's defeat in World War II the company had to close down since production and research of aircraft was prohibited by the Supreme Commander of Allied Powers. This had a severe impact on Nakajima because it was one of the two largest aircraft manufacturers, together with Mitsubishi Heavy Industries (MHI). Unlike MHI though, it was not diversified into shipbuilding and general machinery, and so had to dissolve into a number of spin-off companies set up by former managers, engineers, and workers. As a result, leading aeronautical engineers from NAC, such as Ryoichi Nakagawa, helped transform Japan's automobile industry.
