I'm a veteran game developer and a contributor to several websites, including Gamasutra and Gurashii.

I have worked mainly as a producer and director for 18 years in the industry. 
During the years I worked at EAD in Nintendo since 1999 to until 2008, I developed many game titles, like Pikmin, Pikmin2 (as a planner & scenario writer), Super Mario64DS  (as a sub director), WiiPlay (as a chief director), Wii Fit (as a training & games director), and so on. Also, at first I was a graphics programmer developing JSystem, 3D graphics engine used to most EAD titles like Super Mario Sunshine, The Legend of Zelda: The Wind Waker, Pikmin2, The Legend of Zelda: Twilight Princess, and other EAD titles.

After I went indevendent from Nintendo in 2008, I started my company, entersphere,developing social media, console games and mobile games.

We released a social media "fg" -- sharing photos of prastic models, character figures, sculptuers,and others. Our team developed a hundheld game Army Corps of Hell (PSV) and some social games of "Evangelion", "City Hunter", "Card Fight Vanguard"(for GREE), and so on.

I resigned from my company's CEO last year. And now I work as a game producer at a Japanese famous publisher.
