Koei Tecmo is a Japanese video game development studio and publisher, most well-known for franchises such as Dynasty Warriors, Dead or Alive, and Ninja Gaiden. Based in Yokohama, the company was founded in 2009 as the result of a merger between Koei and Tecmo.
In September 2008, Tecmo announced plans to merge with Koei, following the refusal of a buyout offer from Square Enix. The details of the deal were later finalized by both companies, who agreed to a stock merger worth ¥20 billion (USD$207 million) effective April 1. Although the deal initially faced some opposition from shareholders, it was finally approved by late January 2009, and both companies transferred stock to a new holdings company, Tecmo Koei Holdings.
In March 2010, Koei and Tecmo's development divisions were spun off into their own subsidiaries.
In April of 2010, Tecmo was officially disbanded and dissolved into Koei, which was renamed to Tecmo Koei Games.
In February of 2011, Tecmo Koei announced that its previously spun-off game development subsidiaries would be merged into Tecmo Koei Games effective April 1.
Tecmo Koei announced a global name change to Koei Tecmo in July of 2014.
