Jack the Ripper (暴行切り裂きジャック, Bōkō Kirisaki Jakku) is a 1976 Japanese film in Nikkatsu's Roman Porno series (in the "Violent Pink" subgenre).

A young couple engage in a rampage of murder, rape, and mayhem in order to stimulate their sexual appetites.

[citation needed] Actress Tamaki Katsura had long hair before taking her role for this film.

Realizing that this would limit her career choices for a time, Katsura nevertheless agreed to the change in hairstyle for the film.

Jack the Ripper was released on DVD in Japan on March 21, 2007, as part of Geneon's seventh wave of Nikkatsu Roman porno series.
