Koei Tecmo

The company was established on April 1, 2009, following the merger of the veteran Japanese developers Koei and Tecmo. This consolidation united Koei's expertise in historical simulations and tactical action with Tecmo's legacy in action and fighting genres.

During its inaugural year, the newly formed entity managed a diverse portfolio of releases and localizations. It expanded its crossover tactical action intellectual properties with Warriors Orochi and released Shin Sangoku Musou 5 Empires, which integrated strategic elements into its established action gameplay. The company also catered to role-playing game audiences with the PlayStation Portable release Zill O'll Infinite Plus.

In addition to internal development, the publisher handled regional distribution and localization for major international properties. In 2009, it brought Electronic Arts' Red Alert 3 - Ultimate Edition to the Japanese PlayStation 3 market and localized the video game adaptation of Disney-Pixar's Up. That same year, the company continued its long-running historical simulation tradition with the release of Nobunaga no Yabou: Tendou. Through these strategic releases and distribution partnerships, the merged corporation solidified its financial footing and global market presence.
