Pink film

Pink film (ピンク映画, Pinku eiga) refers in Japan to movies produced by independent studios that includes nudity (hence 'pink') or deals with sexual content. This encompasses everything from dramas to action thrillers and exploitation film features. Many pink films would be analogous to erotic thrillers such as Fatal Attraction or Basic Instinct.

Independent studios that release pink films include OP Eiga, Shintōhō Eiga, Kokuei and Xces. The phrase 'pink film' came into use after the major Toei began advertising some of its movies as 'porno' in 1971 and another major Nikkatsu switched to producing only Roman Porno films later that year.

Until the early 2000s, they were almost exclusively shot on 35 mm film. Recently, filmmakers have increasingly used video (while retaining their emphasis on soft-core narrative). Many theaters swapped 35mm for video projectors and began relying on old videos to meet the demand of triple-feature showings.

Films that are now regarded as pink films became wildly popular in the mid-1960s, and made up a large part of the Japanese domestic market through the mid-1980s. In the 1960s, the pink films were largely the product of small, independent studios. Around 1970, the major studio Nikkatsu started focusing almost exclusively on erotic content, but Toei, another major film production company, started producing a line of what came to be known as Pinky Violence films. With their access to higher production values and talent, some of these films became critical and popular successes. Though the appearance of the adult video led viewers to move away from pink film in the 1980s, films in this genre are still being produced.

The "pink film", or "eroduction" (erotic production) as it was first called, is a cinematic genre without an exact equivalent in the West. Though called pornography, the terms "erotica", "soft porn" and "sexploitation" have been suggested as more appropriate, although none of these precisely matches the pink film genre.

The Japanese film ethics board Eirin has long enforced a ban on the display of genitals and pubic hair. This restriction forced Japanese filmmakers to develop sometimes elaborate means of avoiding showing the "working parts", as American film historian Donald Richie puts it. He wrote:

The eroductions are the limpest of softcore, and though there is much breast and buttock display, though there are simulations of intercourse, none of the working parts are ever shown. Indeed, one pubic hair breaks an unwritten but closely observed code. Though this last problem is solved by shaving the actresses, the larger remains: how to stimulate when the means are missing.

To work around this censorship, most Japanese directors positioned props—lamps, candles, bottles, etc.—at strategic locations to block the banned body parts. When this was not done, the most common alternative techniques are digital scrambling, covering the prohibited area with a black box or a fuzzy white spot, known as a mosaic or "fogging".
