Many books have been written about Japan's surrender in World War II, but the definitive story can only be told by the Japanese themselves. This brilliant reconstruction of the bitter hours preceding the surrender announcement of Emperor Hirohito is based on material compiled by the Pacific War Research Society, a panel of distinguished Japanese authors and journalists. In minute and vivid detail it relates the history-making events of the brief twenty-four-hour period before the Emperor's broadcast that changed the course of nations--and the lives of millions.

During those hours--while hot-blooded young army officers were in violent conflict about whether to surrender or not--one man, General Korechika Anami, Minister of War, with his indomitable will and loyalty, stood firm in his conviction that the Emperor's word must be obeyed. That conviction led him to the supreme sacrifice, sepukku, and his country to peace.

Japan's Longest Day is a penetrating document on the tragic personalities who played out their last great roles on the crumbling stage that was the Imperial Empire of Japan.
