Tecmo Koei
On June 23, 2009, Tecmo Koei announced a planned restructure of its international subsidiaries. Koei Europe was renamed Tecmo Koei Europe in 2009 and became the first subsidiary to publish games under the new moniker, starting with "Ninja Gaiden Sigma 2". In August 2009 Tecmo Koei announced that it was setting up a subsidiary in Hanoi, Vietnam. In January 2010, Tecmo's sole subsidiary, the American Tecmo Inc., and Koei's American branch, Koei Corporation, were moved under a newly formed Tecmo Koei America Corporation, itself a direct subsidiary to Tecmo Koei Holdings. Koei's Canadian, Korean, and Taiwanese subsidiaries were re-branded Tecmo Koei, and also moved to direct subsidiaries of the holding company. Later that month the Entertainment Software Association (ESA) announced that Tecmo Koei was now a member.
