His scripts for kaiju films have been noted for their inventiveness and for having a more lightweight, "fun" tone than those written by Takeshi Kimura (aka Kaoru Mabuchi), another leading writer of kaiju films, whose scripts had a darker, more serious sensibility.
Before embarking on his screenwriting career, he briefly attended an animation school with famed manga artist and animator Osamu Tezuka.
