The Eel (Japanese: うなぎ, Unagi) is a 1997 film directed by Shohei Imamura and starring Koji Yakusho, Misa Shimizu, Mitsuko Baisho and Akira Emoto. The film is loosely based on the novel On Parole by celebrated author Akira Yoshimura, combined with elements from the director's 1966 film The Pornographers. It won the Palme d'Or at the 1997 Cannes Film Festival.
Acting on the advice of an anonymous note, Takuro Yamashita (Kôji Yakusho) returns home early one night to find his wife in bed with another man. He kills her and then turns himself in to the police. After being released from prison, he opens a barber shop. He helps save Keiko Hattori (Misa Shimizu) from a suicide attempt, after which she works at his shop. It becomes clear that Keiko has romantic affections for Takuro, but his reciprocation is redirected towards his pet eel.
