FHI is the successor to Nakajima Aircraft, which was originally established as an Aircraft Research Laboratory.
The laboratory was founded in 1917 by Chikuhei Nakajima (1884-1949) in Gunma Prefecture (approximately 70 km north of Tokyo), and is now the location of Subaru's main modern production base.
Nakajima was the eldest son of a farmer in Gunma Prefecture. At the age of 19, he entered the naval academy, and there he was caught by the news of the first successful plane flight carried out in the United States by the Wright brothers.
Nakajima became very interested in the dream and romance of the sky and wanted to participate in the process of creating aircraft for the Japanese armed forces, but, instead of studying the process of developing and manufacturing aircraft, he left the army and organized the Aviation Research Laboratory.
The laboratory soon became Nakajima Aircraft Co., Ltd. This renaming highlighted the fact that the Company has moved on a par with the leading aircraft manufacturers in Japan.
However, by the time of the end of WWII in 1945, the production of aircraft was stopped.
The company was able to make a new start under a different name Fuji Sangyo Co., ltd, and the first thing that had to be started with a thorough search for other consumers of those high technologies that were used in the aviation industry.
