Critical appraisal
Director Kan Mukai was known for both his sex-oriented pink films and for his adeptness with action. In their Japanese Cinema Encyclopedia: The Sex Films the Weissers write that with Modern Female Ninja: Flesh Hell Mukai combined his talents for both genres into one film. They give the film three out of four stars, characterizing it as, "Tongue-in-cheek fun, combining some surprisingly vicious S&M sequences with campy female-ninja hijinx." One of the earlier films from Mukai's independent Mukai Studios, the Weissers speculate that this film may have been an inspiration for director Masahiro Kasai's popular Female Neo Ninjas (1991).
