Over the past 70 years Benkan Kikoh has evolved from small-scale factory for Buttwelding Fittings to the leading manufacturer in Japan.
Benkan Kikoh has been accumulating and inheriting the technical capabilities and the reliability of manufacturing from Benkan and Sumitomo Metal Industries. In detail, NIPPON BENKAN KOGYO (former BENKAN Corporation) established in 1947 and FUSO KIKOH (former NIPPON STEEL & SUMIKIN KIKOH COMPANY, LTD) became independent from Sumitomo Metal Industries in 1957.
Our company succeeded in the domestic production of buttwelding fittings, built a factory in Ota-ku, Tokyo in 1951, and started manufacturing.
We have gradually expanded our domestic factories, current Amagasaki factory started manufacturing the buttwelding fittings in 1953, Kiryu factory (current Kiryu branch) was established in 1960, Osaka factory was established in 1965, and Yabutsuka factory (current Kiryu factory) was established in 1971.
