Koei Tecmo is a Japanese video game developer and publisher. It is currently a fusion of three former companies: Tecmo, Koei, and Gust. Developers work in one of the three major divisions and are credited separately under the Koei Tecmo label.
Tecmo was originally known as Tehkan Ltd and founded in 1967. Their name was changed in 1986 to Tecmo, Ltd. 2008 was a major year for Tecmo; not only did one of their primary designers, Tomonobu Itagaki, quit due to legal disputes, but in August of the year, Square Enix offered to purchase the company, similar to how they did in 2005 with Taito.
Koei was a Japanese video game publisher, developer, and distributor founded in 1978. It started as a textile dying business before its founder, Yoichi Erikawa, started authoring historical simulation titles in 1980. Their computer games gained popularity in Japan since they were the few which offered non-adult oriented computer products.
Tecmo later opted to merge with Koei. In North America, games from Tecmo or Koei are now published by Tecmo Koei America Corporation. In 2014, the company changed its name in the west to what it is called in Japan, Koei Tecmo. In the summer of 2014, they had also absorbed Gust into its pool of developers.
In 2016, Koei Tecmo announced a reorganization. This reorganization retired Team Tachyon and generic Koei and Tecmo teams funneling several into a new team called Kou Shibusawa and the rest were added to other old teams.
Both companies kept their respective development teams after the merger. Like each of the company's teams, Gust retains its individual developer credits for their games.
- Team Ninja - Tecmo team behind the Dead or Alive series and the Ninja Gaiden series.
- Team Tachyon - Retired Tecmo team retired in 2016 that worked on Fatal Frame series and various individual projects.

- Gust - Acquired Role-playing game developer most known for its Atelier series.
- Kou Shibusawa - team formed in 2016 to develop the historical strategy titles like Nobunaga's Ambition as well as horse simulation games like Winning Post.

Other arcade games from Tecmo include Tecmo Bowl, Ninja Gaiden, Star Force, and Rygar.
