What 1945 declaration set out the Allies' terms for Japan's surrender?

The Potsdam Declaration set out the Allies' terms for Japan's surrender in 1945.

The United States, the United Kingdom, and China issued the declaration on 26 July 1945 during the Potsdam Conference. It called for Japan's unconditional surrender and warned of “prompt and utter destruction” if Japan refused. The Soviet Union joined the war against Japan later and was not an original signatory to the declaration.

The document also described broad postwar conditions, including the occupation of Japanese territory, the disarmament of Japanese forces, and the restriction of Japanese sovereignty to the home islands and other islands determined by the Allies.

Japan accepted the declaration's terms in August after the atomic bombings, the Soviet declaration of war, and internal political debate. Hirohito's 15 August broadcast announced that acceptance, while the formal surrender was signed on 2 September.
