Yokohama, Japan-based developer and publisher Koei has confirmed that its president and chief operating officer, Kiyoshi Komatsu, has left the company. He will be replaced by the current head of the online and mobile games division, Kenji Matsubara. (CORRECTION: GameSpot initially reported that Komatsu was Koei's CEO. That position is held by Masaru Iyori, who is retaining his post. GameSpot regrets the error.)
Koei was established in 1978 by cofounders Yoichi and Keiko Erikawa and is best known for the Dynasty Warriors and Samurai Warriors series of games. The company is currently working on a variety of titles for next-gen platforms, including the role-playing game Opoona (working title) for the Wii and multiplatformers Bladestorm: The Hundred Years' War and Fatal Inertia.
A Koei spokesperson confirmed Komatsu's departure and replacement by Matsubara but declined to issue a statement or give further comment on his reasons for leaving.
