小原宏裕，Koyu Ohara (小原宏裕 - Ohara Koyu) is a Japanese film director best known known for his popular Roman Porno films, Fairy In A Cage (1977) and the Pink Tush Girl series (1978-1980). One of Nikkatsu's most versatile and prolific directors, filming eight movies in 1979 alone, his stylistic preoccupations led him to be known as "King of Pop Art Porn." Early life Koyu Ohara attributes his interest in film to the fact that his grandfather had worked at Nikkatsu as a director. As a child, he claims to have seen up to 200 movies a year. Though he studied law at Keio University and worked as a secretary to a member of the House of Representatives, rather than take the bar exam, he took an entrance exam at Shochiku studios. He failed the Shochiku exam, but tried out for Nikkatsu, and began working there as an assistant director in 1961. He was assigned to director Koreyoshi Kurahara, under whom he worked with future pink film master, Tatsumi Kumashiro. *Passionate: Ohichi's Love Song ((Jouen Ohichi no koiuta) (1972) (debut) * College Girls: Sex Equation (女子大生 ＳＥＸ方程式 - Joshidaisei: Sex hoteishiki (January 12, 1973) * Japan's Pleasure District: Three Sisters at a Turkish Bath (にっぽん歓楽地帯 トルコ三姉妹 - Nippon kanraku-chitai: toruko sanshimai) (April 4, [[1973) * Secret of the College Girls: Part-Time Sex Pros aka Sex Phobia (（秘）女子大生 ＳＥＸアルバイト - Maruhi joshidaisei: Sex arbeit) (January 26, 1974) * Man & Woman Sexology: Private Lessons (男女性事学 個人授業 - Danjo seiji-gaku: kojin jugyo) (June 8, 1974) * True Story of Woman Condemned: Sex Hell (実録おんな鑑別所 性地獄 - Jitsuroku onna kanbetsusho: sei-jigoku) (March 5, 1975) * True Story of Woman Condemned Continues (Zoku jitsuroku onna kanbetsusho - 続実録おんな鑑別所) (July 1, 1975) * White Female Cat: Ecstasy at High Noon (白い牝猫 真昼のエクスタシー - Shiroi mesuneko: mahiru no ecstasy) (November 1, 1975) * New True Story of Woman Condemned to Hell (新・実録おんな鑑別所 －恋獄－ - Shin jitsuroku onna kanbetsusho rengoku) (January 24, 1976) * Runa's Confession: "Men Crawling All Over Me" (ルナの告
