In the fine biographical movie MacArthur which starred Gregory Peck as the controversial general only a small part was devoted to the years as Supreme Commander Allied Powers in charge of the occupation of Japan. Even liberal historians give Douglas MacArthur credit for the vast and peaceful societal change that our occupation of Japan post World War II wrought. We haven't been that successful since. And only a part of that part of the movie concerned the decision about the Emperor's fate.
Emperor concerns those fateful first days of the occupation when MacArthur made the decision not to try the Emperor or members of the royal family as war criminals. Doing the investigation on MacArthur's behalf was General Bonner Fellers who was an army intelligence officer with a background in Japanese language and culture. Matthew Fox is General Fellers and he's got another mission for himself, to find an exchange student from Japan from his youth and whom he knew up to the declaration of war between the USA and Japan.
Tommy Lee Jones plays MacArthur and while he doesn't have that majestic cultured voice that MacArthur had, he still creates a good impression of the imperious general who had a dislike of civil authority. In fact traces of the behavior that got him sacked by Harry Truman during the Korean War are shown. In this case though MacArthur with help of Fellers and his own knowledge of the Asian scene had the right instincts.
The Emperor of Japan centuries ago was a true ruler and over the centuries evolved into a constitutional monarch. But not the same as that Windsor family that reigns in the United Kingdom. The Japanese Shinto religion conferred divine status, the original emperor one Jimmu Tenno is supposed to be descended from the sun god. Japan's wars and foreign policy were done in his name, still are to some extent. A greater decision from Hirohito's part came when he said that he and his family were not divine.
Not covered in this film was the fact that Hirohito had some brothers, at least one of them would have been a more than willing tool of the army and navy chiefs who conducted Japan's war. He faced until the surrender the distinct possibility of being overthrown himself by one of his siblings.
Matthew Fox and Tommy Lee Jones and the Japanese cast are perfectly cast in their roles and I recommend this film as good entertainment and for those with an interest in the Far East.
