Which declaration set the Allied terms for Japan's surrender on 26 July 1945?

The Potsdam Declaration set the Allied terms for Japan's surrender on 26 July 1945.

The United States, the United Kingdom, and China issued the declaration during the Potsdam Conference. It called for the unconditional surrender of Japan's armed forces and warned that the alternative was “prompt and utter destruction.” The Soviet Union did not initially sign it because it was not yet at war with Japan, but later adhered to its terms.

The declaration promised that Japan would not be enslaved or destroyed as a nation, while demanding disarmament, occupation of specified points, punishment of war criminals, and the removal of militarist influence. It also stated that Japanese sovereignty would be limited to the main islands and other territories designated by the Allies.

Japan did not immediately accept the declaration. After the atomic bombings, the Soviet declaration of war, and intense internal debate, Japan notified the Allies that it accepted the terms, with the formal surrender following on 2 September.
