Yokohama War Crimes Trials

The Yokohama War Crimes Trials was a series of trials of 996 Japanese war criminals, held before the military commission of the U.S. 8th Army at Yokohama immediately after the Second World War. The defendants belonged to class B and C, as defined by the charter of the International Military Tribunal for the Far East. Of those tried, 854 defendants were convicted, with 124 of them receiving death sentences, of which 51 were carried out. All of the convicts served their sentences or were executed at Sugamo Prison. In 1958, those still serving prison sentences from the trials were all paroled.
