The studio gave its "Roman porno" directors a great deal of artistic freedom. Beyond budgetary and time restraints, the only rule was that the film meet the official minimum quota of four nude or sex scenes per hour. Patrick Macias notes the diversity of styles this format allowed. Director Chūsei Sone "specialized in ribald tales from the past", Yasuharu Hasebe, "delivered frightening, raw, and violent images", and Tanaka created films which were "as sophisticated as they were erotic." In later years, reflecting on his work in the genre, Tanaka pointed out, "We can look at the core of human beings without disguising anything and can express ourselves very honestly. That's why working on "Roman porno" is such an enjoyable experience."
