Anybody know the title for a movie set in Japan with amazing photography set around Okinawa in...?

Question:

...the 70's?
I saw this 30 years or so ago in Portugal where it was titled Okinawa, but have no idea what the English title may have been. Movie has some references to world war two and what may have transpired during the American occupation, but it's set roughly in the 1970's

Answer:

Battle of Okinawa is a film directed by the now legendary Kihachi Okamoto. It stars Tatsuya Nakadai and Tetsuro "I'm in every Japanese film" Tamba. Both show off their acting chops in this film and deliver outstanding performances. Don't get me wrong though, there are dozens of actors in this film with almost equal scream time as these two men. This is definitely an ensemble piece on one of the most gruesome slaughters on the Japanese armies front. This film is not easy to watch. It is much more violent than "Letters From Iwo Jima" and as in "Iwo" we see how fanatical the Japanese army was at this point in history. Being taken prisoner was not an option and losing meant death or forever living in dishonor. This notion is even implemented to civilians who in this move kill themselves in droves. Tatsuya Nakadai's character is one of the few characters who believes that suicide in not the only option in defeat. He is the western voice in the film for his character even studied in America. This is a hard core war film that takes no prisoners. I recommend you go out and buy this film for it is now available in R1 DVD thanks to the fine folks at AnimEigo.
