Delinquent Girl Boss: Ballad of Yokohama Hoods 1971

Asian Erotica From Japan
Non-Pinku + Pinku eiga

Pink film (Pinku eiga or Pink eiga or Roman Porno) in its broadest sense includes almost any Japanese theatrical film that includes nudity (hence 'pink') or deals with sex. This encompasses everything from dramas to action thrillers and exploitation film features. (source: wikipedia)
Pinku Eiga (also known as Roman Porno)

Pinky Violence is a film genre that developed out of the Japanese New Wave in the late sixties and blossomed into it’s own during the early seventies. The term came from the way the films mixed the erotic elements found in Pink Films (a.k.a. Roman Porno) with the action and violence found in Yakuza crime films. They are often grouped in with sexploitation films because of their excessive nudity, over the top gore and low budget production.

Pinky Violence Vs Pinku Eiga (also known as Roman Porno).
A true 'Pinky Violence' film contains little or no softcore sex scenes and focuses more on violence. They have a strong female lead(s) and often revenge is a major theme. Other popular themes are rival girl gangs clashing and prison settings.
Major studio Toei led the charge in developing violent pink films and produced the vast majority of them. Toho and Nikkatsu each produced about a half dozen films during the height of the pinky violence era which was the 5 year period from 1969 to 1974.
