Hiromichi Tanaka was born January 7, 1962. Classmates with Hironobu Sakaguchi, the two game developers dropped out of Yokohama National University in 1982 to intern at Square, a newly formed software branch of the Denyuusha Electric Company. It was there that they met Kazuhiko Aoki, part of Square's original Planning and Development department. The three of them headed Square's original trio of design groups: Sakaguchi heading A Team, Tanaka leading B Team, and C Team later being formed by Aoki.
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.
On the 24th of June, 2012, Tanaka announced his retirement from Square Enix due to being diagnosed with a serious disease. He has advised he wants to return to the games industry in the future as an independent creator12.
