Which 1945 declaration set out Allied terms demanding Japan's surrender?

The Potsdam Declaration set out the Allied terms demanding Japan's surrender in 1945.

The United States, United Kingdom, and China issued the declaration on 26 July 1945 during the Potsdam Conference. It called for the unconditional surrender of Japan's armed forces and warned that the alternative would be “prompt and utter destruction.” The Soviet Union did not initially sign it because it was not yet at war with Japan.

The declaration also described postwar conditions, including the occupation of Japanese territory, disarmament of Japanese forces, punishment of war criminals, and the removal of militarist influence. It stated that Japanese sovereignty would be limited to the home islands and other islands designated by the Allies.

Japan did not immediately accept the ultimatum. After the atomic bombings and the Soviet entry into the war, Emperor Hirohito directed the government to accept its terms. The later surrender instrument formally recorded that acceptance.
