This movie is about four male high school students who took their university entrance exams and are just hanging around mostly. They have a connection with their teacher Mr. Otake and they go out drinking with him and 3 female classmates. Mr. Otake starts singing a bawdy Japanese folk song, a song sung throughout the film by the male characters. One night after heavy drinking, Otake pays for the girls and guys to stay at an inn since the trains have stopped running. Otake puts on the gas stove, falls drunkenly asleep and accidentally kills himself by poisoning. The girls are inconsolable, the guys nonchalant. The guys become obsessed with a fellow classmate, mostly known by her seat number 469. The film goes from there, with meeting her, meeting Otake's mistress and singing the song. This take on disenfranchised youth in Tokyo is very effective. Director Oshima Nagisa is well known for pushing the envelope (he directed the notorious "In The Realm Of The Senses")and this character study is interesting, with good young actors in the pivotal roles. The movie title notwithstanding, this is not a pornographic film, it has very little nudity and very little violence. Its just a story of attitude, indifference and, if not fear, wariness of what lies ahead. I liked the pacing in this film and generally feel you'll like it if you like Japanese drama. Not perfect, but an interesting film from a maverick director who has no problem making you think.
