Treaty of San Francisco

The 1951 peace treaty formally ended the state of war between Japan and most Allied powers after World War II. It restored Japan’s sovereignty in 1952 while leaving several territorial disputes unresolved.

Occupation of Japan: The Allied military occupation that governed Japan from 1945 until 1952. The treaty set the terms for ending the occupation and restoring Japanese sovereignty.
World War II: A global war fought from 1939 to 1945 between the Axis powers and the Allies. Japan’s defeat in this war created the need for a formal peace settlement.
Article 1 of the Treaty of San Francisco: The treaty article that formally ended the state of war between Japan and the Allied powers that ratified it. This provision states the treaty’s direct legal effect on wartime relations.
Treaty of Taipei: The 1952 treaty that established peace between Japan and the Republic of China. It separately addressed relations with the Chinese government excluded from the San Francisco conference.
Japanese sovereignty: Japan’s authority to govern itself as an independent state. The treaty’s central effect was ending the occupation and restoring Japan’s sovereignty.
Potsdam Declaration: The 1945 Allied ultimatum calling for Japan’s surrender and outlining postwar conditions. Its surrender terms established the framework from which the peace settlement developed.
Japanese reparations: Compensation sought from Japan for damage caused by its wartime actions. The treaty addressed reparations through renunciations and agreements to negotiate with affected countries.
Soviet–Japanese Joint Declaration of 1956: An agreement that restored diplomatic relations between Japan and the Soviet Union without concluding a peace treaty. The Soviet Union did not sign the 1951 treaty, so this declaration addressed their unresolved state of war.
Okinawa: A Japanese island group that remained under United States administration after Japan regained sovereignty in 1952. The treaty separated Okinawa’s administration from Japan’s restored sovereignty.
Allied occupation of Japan: The Allied administration of Japan after its 1945 surrender, led by the United States. Occupation authorities helped shape the settlement that ended their rule.
