Flower and Snake (花と蛇, Hana to hebi) a.k.a. Flowers and Serpents (1974) is a Japanese pink film starring Naomi Tani, directed by Masaru Konuma and produced by Nikkatsu. Based on a novel by Oniroku Dan (born 1931), Japan's best-known author of sadomasochistic (S&M) fiction, Flower and Snake was the first of Nikkatsu's Roman Porno films to deal with an S&M theme. Together with the later Wife to Be Sacrificed (also directed by Konuma in 1974, and starring the same female and male leads) this film is credited with starting the S&M Roman Porno series which helped save Nikkatsu from financial collapse during the 1970s.
