An international military tribunal was also convened in Tokyo to prosecute Japanese military officials accused of war crimes. A total of twenty-five high-ranking Japanese officers were tried, most of them charged with crimes against peace, crimes against humanity, and atrocities.

Unlike the Nuremberg trials, which were closely watched by most Americans, the trials in Japan drew little interest. The most popular trial was that of Japan's prime minister, Hideki Tojo, who was the Japanese equivalent of Adolf Hitler in the eyes of most Americans. The trials lasted for nearly three years. At the end, Tojo and six others were found guilty and sentenced to death by hanging; sixteen others were sentenced to life in prison. Additional war crimes trials were conducted in other Far East nations, where another 900 Japanese military officials were sentenced to death.
