What document did Japan sign aboard USS Missouri to formalize its 1945 surrender?

Japan signed the Japanese Instrument of Surrender aboard USS Missouri to formalize its surrender on 2 September 1945.

The instrument was the printed agreement that brought hostilities between Japan and the Allied powers to an official end. It required Japan to accept the terms of the Potsdam Declaration and ordered Japanese forces to cease resistance and surrender their weapons.

Mamoru Shigemitsu signed first for the Japanese government, followed by General Yoshijiro Umezu for Imperial General Headquarters. General Douglas MacArthur signed for the Allied powers, and representatives of the United States, China, the United Kingdom, the Soviet Union, Australia, Canada, France, the Netherlands, and New Zealand also signed.

The instrument should not be confused with the Treaty of San Francisco. The surrender document ended wartime hostilities, while the later peace treaty established a broader postwar legal settlement. The Treaty of San Francisco was signed in 1951 and entered into force in 1952.
