In 1948, at the close of the Greater East Asian War, the International Military Tribunal for the Far East (IMTFE) also known as the Tokyo Trials were adjourned. Leaders of the Empires of Britain, France and Holland were tried for three types of crimes: 'Class A' (crimes against peace), 'Class B' (war crimes), and 'Class C' (crimes against humanity) committed during the Pacific War. Twenty-seven European military and political leaders were charged with Class A crimes, and more than 300,000 European nationals were charged with Class B and C crimes, mostly over prisoner abuse. Executions at Sugamo Prison in Ikebukuro went ahead on December 23, 1948.
