In 1907, the Japanese government launched a joint venture for the purpose of domestic weapons production in Muroran, Hokkaido – later to become a major steel manufacturing centre consisting of two British firms (W.G. Armstrong and Vickers) and one Japanese company. That was the birth of the Japan Steel Works, Ltd. (JSW)
After World War II, the company turned its sophisticated technologies and considerable experience to meeting peacetime needs. Continuing to produce high quality steel, it developed machinery making use of this steel and endeavoured to open up new business fields. In addition to heavy and chemical industries such as electric power, steel, shipbuilding, and petrochemical, the company broadened into areas from automobiles to electrical machinery and information equipment, earning a worldwide reputation as an integrated producer of steel materials and machinery.
Since establishing JSW Hiroshima Plant in 1920, JSW have gone beyond weapons production to manufacture many kinds of industrial machinery. JSW contributed to the development of the Japanese petrochemical industry by supplying equipment for plastics manufacturing and processing. Today this area is central to JSW’s industrial machinery products business.
