In adapting several stories by Japan’s master of weird fiction Edogawa Rampo (a pseudonym: say the name aloud and you’ll get the reference to a certain American writer of terror tales), Teruo Ishii produces a masterpiece of the “ero-guro-nansensu” (erotic-grotesque-nonsense) thread of Japanese pulp art. Starting in an insane asylum and ending on a psychedelically rendered island of miscreants, it is truly a fascinating artifact of its times.
