Kobayashi's name in the history of cinema was ensured when he directed the first pink film, Flesh Market, in 1962 at Ōkura Eiga.
[8] When the police confiscated the film, two days after its release, the studio quickly patched together another version from extra footage, and Flesh Market became a huge success.
His trilogy of films beginning with Conception and Venereal Disease (1968) was an example of this genre, in which an innocent country girl is corrupted by life in the big city.
A 1969 report from Kinema Jumpo indicated that some of Ogawa's films for Ōkura, including 1966-06 Desires of an Abnormal Man (欲望の異常者, Yokubō no Ijōsha) (June 1966) and College Coed's Forbidden Flower Garden (女子大生の禁じられた花園, Joshidaisei no Kinjirareta Hanazono) (September 1967) had been exported and shown in England.
However Jasper Sharp reports that several pink film insiders are skeptical of this claim, as Ōgimachi was Mitsugu Ōkura's mistress, and he was known to treat her with favoritism.
[22] The Weissers write that standard Ōkura Eiga product of the 1960s was a low-budget affair with a forgettable plot which existed only to provide actresses to appear in the nude.
[25] After her career got off to a bad start with cult horror director Kinnosuke Fukada's disastrous foray into pink, Pleasure Trap (Kairaku no Wana, Kokuei, early 1967), actress Keiko Kayama took the unusual step for the time of initiating a publicity campaign.
Following this successful move, she became one of the leading sex film actresses of the era, starring in such box-office hits for Ōkura as Pleasure of Women (女のよろこび, Onna no Yorokobi) (April 1967).
[26] Ōkura gave future "SM Queen", actress Naomi Tani her first taste of the SM genre in Memoirs of a Modern Female Doctor aka Contemporary Medical Science on Women and Two Stories Of Sex (現代女性医学, Gendai Joi Igaku) (May 1967), and her first role in a fully SM-themed film with Cruel Map of Women's Bodies aka Female Bodies in a Brutal Scenario (女体残虐図, Jotai Zangyakuzu) (October, 1967).
[29] Typical of the studio's output in the 1980s, director Kazuhisa Ogawa, with regular star Mayumi Sanjo specialized in a series of college girl films.
[30] Rape Pornography (犯しの淫画, Okashi No Inga) (February 1983) and Spoiled Relationship (熟れすぎた関係, Uresugita Kankei) (August 1983) were unusually artistically done, thought-provoking films by regular Ōkura director Dai Iizumi.
[39][40] Best Films of the year produced by OP Eiga include Sad and Painful Search: Office Lady Essay (Tarō Araki, 2000), A Saloon Wet with Beautiful Women (Tatsuro Kashihara, 2002), Fascinating Young Hostess: Sexy Thighs (Tetsuya Takehora, 2006), Molester's Train: Sensitive Fingers (Yoshikazu Katō, 2007), and the most recent Best Film, director Yoshikazu Katō's Tsubo Hime Sopu: Nuru Hada de Urazeme (壺姫ソープ ぬる肌で裏責め) (2009).
