Tecmo Koei Holdings Co., Ltd. (コーエーテクモホールディングス株式会社 Kōē Tekumo Hōrudingusu Kabushiki-gaisha?)), is a holding company created in 2009 by the merger of Japanese video game developers and publishers Koei and Tecmo.
Koei Europe changed its name to Tecmo Koei Europe, Ltd and now releases video games under the new moniker. In January 2010, Tecmo, Inc. and Koei Corporation merged into Tecmo Koei America Corporation. Tecmo has been declared disbanded in Japan, effective as of April 1, 2010. Koei Canada, Inc. has since changed its name to Tecmo Koei Canada, Inc.
The continued operating loss prompted Kenji Matsubara, the former president and CEO of both Tecmo Koei Holdings and Tecmo Koei Games label to tendered his resignation in November 2010. Yoichi Erikawa - Co-founder of Koei - will take over the four positions vacated by Kenji Matsubara.
