This poster is an addendum to our earlier write-up on this film, Osoe!, a hit roman porno from Nikkatsu Studios starring Erina Miyai, who spent her entire career getting into pickles like this one. This is basically the original promo poster, reversed and with all the text removed except the title. It was unusual for title-only art like this to be produced, which is why when we found it we thought we'd better share. We also share some thoughts on the film. Just look here. Osoe! premiered in Japan today in 1978. 

This poster was made to promote a Nikkatsu Studios roman porno flick titled Osoe!, which in Japanese means “attack.” In typical roman porno fashion, the plot is pretty twisted. In brief, Erina Miyai plays a woman who wants revenge on a corporation for its role in the death of her parents. She goes to a disco and deliberately allows herself to be taken home and gangbanged, all for the purpose of later informing the guys who did it she'll accuse them of rape if they don't kidnap the corporation's CEO for her.

We'll say this much for Nikkatsu—their ideas were certainly creative. In this case, there's a subtext of turning male power against itself, which is all to the good, but of course things never come off quite how the protagonists intend in roman porno. Which is to say, Miyai's plot goes pear shaped. Osoe! is super obscure in the West but was a successful release and even played a few years ago at the famed Laputa Asagaya revival cinema in Tokyo. Its original premiere was today in 1978.
