One Man's Justice — Akira Yoshimura

It is just after the second World War. Takuya, an officer in Japan's former Imperial Army, is not surprised when he receives a postcard asking him to report to the U.S. Regional Command Headquarters in Tokyo. He assumes that the Americans have learned of his involvement in the execution of prisoners-of-war. Now he is a fugitive in his own country.
He travels on crowded trains through a land of defeat, humiliation, and hunger. With widespread talk of prosecution for war crimes, he fears that his past will be revealed. But why should an honest and dutiful man like him be prosecuted by the very people who dropped atomic bombs on Hiroshima and Nagasaki?
One Man's Justice is an unnerving story of timeless relevance from a master of the psychological novel.
