In the Realm of the Senses is a 1976 erotic art film written and directed by Nagisa Ōshima. It is a fictionalised and sexually explicit treatment of a 1936 murder committed by Sada Abe. An international coproduction of France and Japan, the film generated great controversy at the time of its release. The film had the involvement of pink film luminary Kōji Wakamatsu as co-screenwriter and assistant producer. While intended for mainstream wide release, the film contains scenes of unsimulated sexual activity between the actors.
