This unusual poster was made to promote the Nikkatsu Studios roman porno flick Yogisha no Onna, starring Mari Tanaka, one of hardest working women on Nikkatsu’s roster. She made eighteen films from 1971 to ’73, streaking like a comet across the sexploitation firmament. In Yogisha no Onna she stars as an obviously disturbed woman living with her sister Keiko Tsuzuki in a big, Western style house with their invalid father. The sisters have a love-hate relationship. The love: they share baths. The hate: they share a man. The latter occurs after their father finds Tsuzuki what he thinks is a suitable fiancée, jealousy results, and Tanaka decides that what’s good for the sis is good for the sibling. Where does it all lead? If you want the answer you’ll have to find out for yourself. We’ll just say that as a somewhat early film from the roman porno cycle, Yogisha no Onna is neither unbearably weird nor unconscionably misogynistic, though it’s not exactly a portrait of normal social adjustment either. It’s possible serious fans of the genre will find the movie too tame, but personally, considering where some of the subsequent roman pornos went, tame was just fine with us. Yogisha no Onna premiered in Japan today in 1972.
These sisters do everything together—including men.
