The story
In 1888, a company was formed to provide equipment repair services to the Besshi copper mine. Almost 50 years later, in 1934, the company incorporated as Sumitomo Machinery Co., Ltd. to manufacture machinery for the steel and transportation industries in support of that period of rapid economic growth.
In 1969, Sumitomo Machinery Co., Ltd. merged with Uraga Heavy Industries Co., Ltd. to create Sumitomo Heavy Industries, Ltd. Today, Sumitomo Heavy Industries manufactures injection molding machines, laser systems, semiconductor machinery and liquid crystal production machinery.
In 1979, the company famously built the Seawise Giant, an Ultra Large Crude Carrier (ULCC) supertanker; the longest ship ever built.
In April 2021, it was reported that SHI has ceased making light machine guns for the JSDF, citing a bleak economic prospects in the arms sector.
