Guilty of Romance is a 2011 Japanese erotic romantic thriller film directed by Sion Sono. Sono's screenplay is based on a story by Misue Kunizane, which was inspired by the 1997 murder of Yasuko Watanabe. The plot follows two interweaving storylines, the first involving the investigation of a murder in a Tokyo love hotel district, the second about a neglected wife seeking her carnal desires through nude modeling and prostitution.
