ABOUT US

Background

Our company started in 1938 to produce forgings for fighters including zero-fighters as a subcontractor of the Nakajima Aircraft Company. Since we lost the aircraft market in 1945, we shifted our main business to the forging of special steels. Afterward we added manufacturing of heavy (over 15t) load forktruck forks and forging of super alloys as our core businesses.
