Nagisa Ôshima's first movie as a director is an overt and strident study of class warfare in the new Japan of rich businessmen and the poverty stricken. set in the industrial sections of Tokyo. Although I thought the ending a bit over the top, it's a cleanly written and performed movie with something to say.
