True Story of a Woman in Jail: Sex Hell 1975

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.

A mix of all genres

The women in prison film (or WiP film) is a subgenre of exploitation film that began in the early 1900s and continues to the present day. Their stories feature imprisoned women who are subjected to sexual and physical abuse, typically by sadistic male or female prison wardens, guards and other inmates. The genre also features many films in which imprisoned women engage in lesbian sex. The films of this genre include a mixture of erotic adventures of the women in prison. The flexible format, and the loosening of film censorship laws in the 1960s, allowed filmmakers to depict more extreme fetishes, such as voyeurism (strip searches, group shower scenes, catfights), sexual fantasies (lesbianism, rape, sexual slavery), fetishism (bondage, whipping, degradation), and sadism (beatings, torture, cruelty).
