Along with fellow directors, Kazuhiro Sano, Toshiki Satō, and Hisayasu Sato, he is known as one of the "Four Heavenly Kings of Pink" (ピンク四天王, pinku shitennō).

His style is much less violent than Sato's, and rarely includes rape, one of the traditional thematic staples of the pink film from earliest times.

He has the habit of giving his films eccentric titles during their production which the studios replace with a more commercially exploitable name before release.

For example, Zeze's title My Existence Is a Phenomenon Based on the Hypothesis of Blue Light Generated by Organic Currency was changed to Amazon Garden: Uniform Lesbians.

[4] While continuing to work in the pink film genre, he has since directed several mainstream successes such as Rush!, Hysteric and Dog Star.
