Sumitomo Heavy Industries, Ltd. (住友重機械工業株式会社, Sumitomo Jūkikai Kōgyō Kabushiki-gaisha) (SHI) is an integrated manufacturer of industrial machinery, automatic weaponry, ships, bridges and steel structure, equipment for environmental protection, including recycling, power transmission equipment, plastic molding machines, laser processing systems, particle accelerators, material handling systems, cancer diagnostic and treatment equipment and others.



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. The company continues to innovate and expand to meet the demands of the new market frontiers. 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.
