In 1969, Sumitomo Computer Service Corporation was established by Sumitomo Corporation.[2] In 2005, Sumitomo Computer Service Corporation and Sumitomo Electronics Corporation were merged into Sumitomo Computer System Corporation.
Separately, in 1968, CSK Corporation was established by Japanese entrepreneur Isao Okawa[3] in 1968. The acronym CSK was derived from "Computer Service". CSK established CSK Research Institute, later renamed as CRI Middleware, in 1983. At its peak, the company, the largest independent software company in Japan until it being acquired, was called the CSK Group. In the 2000s, its real estate investment business failed, resulting in heavy losses to the company after Okawa's death in 2001.[4][clarification needed]
In April 2011, Sumitomo Corporation acquired CSK through a takeover. In October 2011, Sumitomo Computer System Corporation and CSK Corporation went through a statutory merger, in which Sumitomo Computer System absorbed CSK Corporation and was re-branded SCSK Corporation.[5]
The company offers the services of system integration, cloud computing, information security and produces computer software in Japan, mostly on a B2B basis for enterprises. SCSK Corporation's business type and scope is similar to those of Itochu Techno-Solutions, Uniadex and Mitsui Knowledge Industry, which also specialize in IT services. The company has been listed on the Tokyo Stock Exchange since 1989, then as Sumitomo Computer Service Corporation.[6]
