What was the name of the Allied document whose terms Japan accepted in August 1945?

Japan accepted the terms of the Potsdam Declaration in August 1945.

The declaration was issued on July 26, 1945, by the United States, the United Kingdom, and China during the Potsdam Conference. It demanded Japan’s unconditional surrender and warned that refusal would bring “prompt and utter destruction.” The Soviet Union was not initially a signatory because it was still neutral toward Japan when the declaration was issued, but it later joined the declaration after entering the war against Japan.

The document promised that Japan would not be destroyed as a nation, while requiring the elimination of militarism, the occupation of specified territory, and the limitation of Japanese sovereignty. It also stated that Japanese forces would be allowed to return home after disarmament.

Japan initially rejected the declaration publicly through the term mokusatsu, whose interpretation remains debated. After the atomic bombings and the Soviet declaration of war, Japan notified the Allies that it accepted the terms, subject to preserving the emperor’s position. The Allies then clarified that the emperor would be subject to the Supreme Commander for the Allied Powers.
