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 'Ero-i 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'.
His real name is SUMI Toshihiko.
