Yokubô no ijôsha

OP Eiga (オーピー映画), also known as Ōkura Eiga (大蔵映画) or Okura Pictures, is the largest and one of the oldest independent Japanese studios which produce and distribute pink films. It was founded in 1961 by Mitsuru Ōkura, former president of film studio Shintōhō. Along with Shintōhō Eiga, Kantō, Million Film, and Kōji Wakamatsu's production studio, Ōkura was one of the most influential studios on the pink film genre. Among the many notable pink films released by the studio are Satoru Kobayashi's Flesh Market (1962), the first film in the pink film genre.
