In Japanese cinema, the theme of incest gained prominence in the 1960s and 1970s, with films like "In the Realm of the Senses" (1976) by Nagisa Ōshima, which explores the complex and doomed relationship between a hotel owner and his maid. While not exclusively focused on incest, the film's themes of obsession and blurred boundaries are reminiscent of incestuous relationships.
