Nudity and sex officially entered Japanese cinema with Satoru Kobayashi's controversial and popular independent production Flesh Market (Nikutai no Ichiba, 1962), which is considered the first true pink film.
In the 1970s, some of Japan's major studios, facing the loss of their theatrical audience, took over the pink film.
