Pink film (ピンク映画 Pinku eiga or Pink eiga?) is a broad cinematic term used to categorize a wide variety of Japanese films with adult content. This encompasses everything from dramas to action thrillers and exploitation films (a.k.a. pinky violence), and softcore pornographic (romance pornography or roman poruno) features. The term is often mistakenly used to apply only to sex films. However, the so-called pink movie is part of an ongoing (and evolving) cycle of films rather than a specific genre.
Pinku eiga, along with the bloody and violent yakuza-eiga, or contemporary gangster film, both became wildly popular in the mid-1960s and dominated the Japanese domestic cinema through the mid-1980s. In the 1960s, the pink films were largely the product of small, independent studios. In the 1970s, some of Japan’s major studios, facing the loss of their theatrical audience, took over the pink film. With their access to higher production-values and talent, some of these films became critical and popular successes. Though the appearance of the AV (adult video) took away most of the pink film audience in the 1980s, films in this genre are still being produced.
