Treaty of San Francisco (サンフランシスコ講和条約 San-Furanshisuko kōwa-Jōyaku?), Peace Treaty with Japan (日本国との平和条約 Nihon-koku tono Heiwa-Jōyaku) or commonly known as the Treaty of Peace with Japan, Peace Treaty of San Francisco, or San Francisco Peace Treaty), mostly between Japan and the Allied Powers, was officially signed by 48 nations on September 8, 1951, at the War Memorial Opera House in San Francisco, California, United States. It came into force on April 28, 1952. According to Article 11 of the Treaty of San Francisco, Japan accepts the judgments of the International Military Tribunal for the Far East and of other Allied War Crimes Courts imposed on Japan both within and outside Japan.
This treaty served to officially end Japan's position as an imperial power, to allocate compensation to Allied civilians and former prisoners of war who had suffered Japanese war crimes during World War II, and to end the Allied post-war occupation of Japan and return sovereignty to that nation. This treaty made extensive use of the United Nations Charter and the Universal Declaration of Human Rights to enunciate the Allies' goals.
