Critical appraisal
In their Japanese Cinema Encyclopedia: The Sex Films, the Weissers give Invisible Man: Rape! a rating of two points out of four. Judging Isai Hayashi to be an "apathetic" and "by-the-numbers" director, they note that this film is one of his best. Besides the interesting theme, they write that the film is helped by a good-looking and competent cast.

Allmovie writes that Invisible Man: Rape! more closely resembles later U.S. teen wish-fulfillment fantasies like Zapped! (1982) and Invisible Maniac (1990) than contemporary rape-themed Roman porno films.

Background
Director Isao Hayashi worked with Nikkatsu from the beginning of the Roman porno era, directing Castle Orgies, one of the first two releases of the series. The Weissers note that it may be Hayashi's work with historical dramas that gives his directorial style a pedantic feel. Along with Lady Kamakura: Cherry Boy Club (1975) Invisible Man: Rape! was one of Hayashi's most successful films.

The lead actress in Invisible Man: Rape!, Izumi Shima, had been promoted as "Nikkatsu's most beautiful actress", and was debuted in Lady Chatterley In Tokyo (1977), a project tailored for her. When that film failed to gain much approval, Shima was given a string of lower-profile projects. Her career was revived in 1982 when SM-author Oniroku Dan chose her to star in his first film production, Dark Hair, Velvet Soul. After that, Shima made a name for herself in the S&M genre, especially with films based on works by Dan, and became regarded as one of Nikkatsu's leading actresses of the 1980s.

Availability
Invisible Man: Rape! was released theatrically in Japan on December 23, 1978. It was released on home video in Japan in VHS format on June 7, 1996.
