アニメーション神戸
In 1999, Ōsaka lectured on an animation workshop at the 4th Animation Kobe event, held in Kobe, Hyōgo Prefecture. An anime fan, he had wanted to be an animator since his high school days, being inspired by Sunrise's iconic 1979 series "Mobile Suit Gundam" and the works of the manga artist Mitsuru Adachi.
