After dropping out of university he entered Yoyogi Animation Gakuin. During his time at the school he joined the animation studio OLM, and worked as a 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, Team Iwasa split from OLM and established itself independently as White Fox.
