This steamy poster was made to promote the roman porno flick Showa onnamichi: Rashomon, aka Showa Woman: Naked Rashomon, aka Naked Rashomon, which starred Hitomi Kozue and Elmei Esumi. In case you're wondering, “rashomon” was an ancient city gate located in what is now Kyoto, which makes the title rather curious, but it's borrowed from the 1950 Akira Kurosawa period drama Rashomon, which used the gate locale as a central element. That film was famous for its four characters narrating four versions of the same terrible event.

Does Naked Rashomon have anything to do with city gates or multi-p.o.v. narratives? Well, no. When a nobleman's wife can't bear him a son, he turns to a mistress to get the job done and she gives birth to twins—a boy and a girl. The boy will be the nobleman's heir; but he orders the mistress and infant daughter killed. The bodyguard responsible for this heinous task instead secretly sends the pair away. Two decades later the daughter has grown up to be a beautiful woman and, unaware of her true ancestry, crosses paths with her father and twin brother with shocking results.

It's a bizarre premise but a good movie, considered one of director Chûsei Sone's best. And it has Pulp Intl. fave Kozue in a double role as both the mistress and her grown daughter, which can only make matters better. Compared to most Nikkatsu Studios roman pornos this one qualifies as high art, which means it's not just recommendable, but is also a reasonable place for the uninitiated to dive into the genre. But you might not want to dive too deep. It gets pretty gnarly down there. Showa onnamichi: Rashomon premiered in Japan today in 1973.
