Born in Japan in 1930, Shogoro Nishimura joined Nikkatsu Studios in 1954, and was first promoted to director in 1963 with the well-received Keirinshô ningyô jôki. He spent the rest of that decade directing Nikkatsu programmers of varying quality. With the 1970s came the studio's shift to making exclusively soft-core "Roman porno" films (usually more story-driven and elaborate than their Western counterparts). Rather than look for work elsewhere, Nishimura found this to be a genre which agreed with him: by the time of his retirement, he had completed fully 83 films in that.
