Gaku Iwasa was born February 5, 1974 in Yokohama, Kanagawa Prefecture, Japan. He is currently the Representative Director of White Fox. After dropping out of university he entered Yoyogi Animation Gakuin. During his time at school he joined OLM, working as production assistant on Mojakou. Quickly thereafter he rose in rank and established his own animation team, Team Iwasa. Their first work was Kasumin. His policy for making anime was to make a "polite work" which is highly regarded by fans. In 2007 the studio split from OLM and established itself independently as White Fox.
