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 for the Allied Powers.
The company was reborn 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.
