I've been a fan of Tohjiro's work/output for quite some time. He's taken porn in very unusual directions. Recently, "output" describes the content he's focusing on.
Frankly, I don't find excessive vomiting terribly erotic, although it does possess a certain Grand Guignol audacity.
The freak show dominates the director's work and, to some extent, that of other Dogma 'auteurs'. Japan's bizarre censorship laws permit explicit focus on the anus and its expulsions while draping quivering mosaic shapes over the vagina and its surroundings.
Ultra-hard S/M remains a constant on Tohjiro's horizon. Although the covers convey a rich aesthetic, the productions themselves often lack such riches -- reduced, unfortunately, to handheld, poorly lit tableaux.
My introduction to Tohjiro was a screening (approximately ten years ago) of the best piece of lesbian erotica I've ever seen. It was a film he produced prior to forming Dogma and involved two beautiful women in a traditional Japanese setting.
