Tanaka's B Team was responsible for the Seiken Densetsu series of games, or World of Mana as they are known in English. After Seiken Densetsu 3, he served as producer on a variety of other game titles, including Xenogears, Threads of Fate, and Chrono Cross.
When Square transitioned to Playstation 2 game development and began its first venture in to mainstream MMO territory with Final Fantasy XI, Tanaka served as producer. As of 2007, he is serving as Senior Vice President of Software Development at Square Enix and one of the central developers of the PlayOnline network. More recently, Tanaka led the production of Final Fantasy III for Nintendo DS, which far surpassed sales forecasts by moving over 1.5 million units in Japan and the United States.
