He makes hentai manga. But not "just" the kind of hentai manga that features as much overt sex as possible and little realistic storyline. Tamaoki's stories display a great sense of psychological detail, and usually end in a refreshing way. He says about his work: "I want to create hentai manga that convey a feeling of everyday life." His first collection was Eroi Hon (Erotic-ish Book) in 1995. His manga has been published in many magazines, and also been published in the USA. One of his best known manga is Blood: the Last Vampire.
