Modern Female Ninja Flesh Hell , Gendai Kunoichi Niku Jigoku? aka Inferno of the Flesh is a 1968 Japanese pink film directed by Kan Mukai. It is in the partcolor format which was used in pink films in the late 1960s and early 1970s before fullcolor was made standard with the introduction of Nikkatsus Roman porno series.
Director Kan Mukai was known for both his sexoriented 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, Tongueincheek fun, combining some surprisingly vicious SampM sequences with campy femaleninja hijinx. One of the earlier films from Mukais independent Mukai Studios, the Weissers speculate that this film may have been an inspiration for director Masahiro Kasais popular Female Neo Ninjas 1991.
