, was a Japanese video game corporation founded in 1967. It had its headquarters in the Kudankita district of Tokyo. Its subsidiary, Tecmo Inc, was located in Torrance, California. Tecmo was formerly known as Tehkan. Tecmo is known for the Captain Tsubasa, Dead or Alive, Deception, Fatal Frame, Gallop Racer, Monster Rancher, Ninja Gaiden, Rygar, Star Force and Tecmo Bowl video game series. When it was still called Tehkan, the company released arcade games such as Bomb Jack, Gridiron Fight and Tehkan World Cup. The company was founded on July 31, 1967, as a supplier of cleaning equipment. By 1969, it started to sell amusement equipment. In 2009, Tecmo merged with Koei to form the holding company Tecmo Koei Holdings and was operated as a subsidiary until its disbandment in early 2010. In April 2010, Tecmo was dissolved and its video game franchises are now published by Koei Tecmo Games. Tecmo is also the name of a distinct video game development company that was established in March 2010, but later folded into Koei Tecmo Games in April 2011. Tecmo Co., Ltd, which merged with Koei in 2009, was itself the combination of two companies: Imperial Trustee Corporation (founded in 1964) and Nippon Yacht Co, Ltd (founded in 1967). The origins of Tecmo dates to September 1964 as the Imperial Trustee Corporation, a company specialized in the management of building maintenance including the supplying of cleaning equipment. In July 1969, the company started to sell entertainment amusement equipment and opened its first self-managed amusement facility in March 1970 in Chiba Prefecture. In October 1977, the Imperial Trustee Corporation was renamed "Tehkan Ltd", with the trade name changed as well to "Tehkan". Tehkan is derived from the name "Teikoku Kanzai", the company's original Japanese name. In March 1981, a U.S. division was inaugurated in Los Angeles as "U.S. Tehkan, Inc.". A month later, in April 1981, Tehkan released in Japan its first internally developed arcade video game, titled "Pleiads" (which was distributed in America by Centuri).
