Facing financial crisis, Nikkatsu shifted toward erotic features and built a prolific schedule. The line became a training ground and a cultural reference point far beyond its original audiences.

Cultural context

In Japan the phrase can signal film-history literacy. Abroad it is sometimes used as flavor text for any Japanese softcore movie.

Common misunderstandings

• Roman porno is not a general word for Japanese pornography.
