This film was a remake of director Hisayasu Sato's earlier 1987 film Genuine Rape, however this version of the film doesn't include any rape and is not pornographic in any means.
This film is most notoriously known for a scene that has been described as "one of the most appalling shown in Japanese horror," though Sato has produced other films that contain some of the most horrific horror and pinkgu films, and Japanese CAT III and other extreme films also have some of the most abhorrent acts of violence ever witnessed on screen.
