Director Fukasaku is best known for his cult classic Battle Royale, as well as numerous yakuza flicks from the '70s. Under the Flag of the Rising Sun is really the film he should best be known for. He produced it independently, and it's easily his most prestigious and all-around exceptional film. It's a WWII movie, made from the perspective of a quarter century later. Sachiko Hidari stars as a war widow in 1971 who is still trying to get benefits from the government, as well as restore her husband's honor. He was supposedly executed in the waning days of the war, but any further information has disappeared. To find the truth, she begins searching for veterans who may have known her husband. She interviews several witnesses who give her a conflicting story of her husband, but a pretty vivid picture of what it might have been like to be a soldier fighting in the New Guinea front. The film isn't exploitative, but it can be explicitly violent (most of the flashbacks are in black and white up until the violence starts - Fukasaku does not want the audience to be separate from that). Under the Flag of the Rising Sun is one of the most unflinching of all the great Japanese WWII films. You really feel the pain that still exists in the early '70s. The sequences with the war veteran teacher, watching over his students who have grown up after the war and are completely innocent of it, are especially gut-wrenching. I also loved the performance of Noboru Mitani, best known for playing the irresponsible homeless father in Kurosawa's Dodeskaden, who plays a veteran with a dark secret.
