Normes, Markus, ed. The Pink Book: the Japanese Eroduction and its Contexts.
"The Japanese eroduction, known locally as the Pink Film (pinku eiga), stands out among its soft-core cousins in other parts of the world for its scale, intimate relationship to the mainstream industry, and its occasional ambition. Pink films are ultra-low budget, soft-core, 35mm narrative feature films. They emerged in the early 1960s and quickly became a significant portion of Japan’s annual output (between 100 and 700 films a year), showing triple bills in their own network of national theater chains. Their success was accomplished in the vacuum left by the crumbling studio system. Today, the industry is itself in its death throes, unable to compete with the more explicit home video market known as AV. Triple bills in air conditioned comfort can no longer compete with the privacy of home. Now is an opportune time to examine the history of the Pink Film, now on the cusp of its disappearance." -- Kinema Club.
