Hakkin nikubuton, aka Banned Book: Flesh Futon, for which you see a poster above, has one of those strange titles you come across occasionally in Japanese cinema. “Banned book” seems straightforward enough. But “flesh futon”? Hmm… Based on an erotic novel by Chinese writer Li Yu and starring Hajime Tanimoto, Maya Hiromi, Terumi Azuma, and Rei Okamoto, the movie tells the story of a poor writer named Mio who unexpectedly authors a bestselling erotic novel called—and this will clear up the title weirdness—Flesh Futon. See? Mio takes to fame quite easily, living in the fast lane and generally having a good time.

But his wonderful life begins to fall apart due to various unexpected misfortunes. These run the gamut from having a prostitute spread a rumor that his penis is “like a guppy,” to having to his house robbed and (now that we understand the title, we know this next part is coming) his book banned. When Mio later encounters the house thief this dodgy character reveals that it’s possible to have one’s penis enlarged. How? Let’s just say it’s a pretty ruff procedure. Mio opts for the surgery, but alas, quickly learns that being a big fish isn’t everything, as his previous misfortunes turn out to be only a taste of what is to come. Hakkin nikubuton premiered in Japan today in 1975.
