Tecmo was originally founded in September of 1964 as Teikoku Kanzai, meaning Imperial Custodianship, specializing in cleaning supplies and building maintenance. In October of 1977, the company shorted its name to Tehkan and eventually changed its business to amusement machines, making and selling things such as UFO catchers and pachinko machines, and later arcade machines.
Before the business change, there was another company that specialized in yachts and other boats named Japan Yacht Ltd. established on July 7, 1967. This company also dove into electronics with arcade games and eventually changed its name to Tehkan Electronics Ltd. on December 6, 1982, and shorted it to just Tehkan Ltd. on April 19, 1985.
Two months later, both Tehkan companies combined into one with the new company's main focus becoming arcade games while still creating other amusement machines. Since the company became primarily known for its video games, the founding date is normally cited with the Japan Yacht Ltd.'s establishment. On January 8, 1986, the company officially changed its name to Tecmo.
| Tecmo's first arcade game it developed was Pleiads in 1980 and brought over to the West by Centuri in 1981. Tecmo continued to make arcade games like Swimmer and Star Force, and in 1984 released their first console game, Guzzler, on the Sega SG-1000. The first Tecmo games to hit a main competitor console were Star Force and Bomb Jack for the NES in 1984, and the first game made exclusively for a console was Tsuppari Oozumou for the NES in 1987.|
