What 1945 Allied declaration demanded Japan’s unconditional surrender before the formal surrender ceremony?

The Potsdam Declaration demanded Japan’s unconditional surrender before the formal surrender ceremony.

Issued on 26 July 1945, the declaration was made by the United States, the United Kingdom, and China. It warned Japan of “prompt and utter destruction” if it refused to surrender, while outlining broad Allied goals for the country’s postwar future.

The declaration followed the Potsdam Conference, where Allied leaders discussed the defeat of Germany and the continuing war against Japan. The Soviet Union did not initially sign it because it was still neutral toward Japan at the time. After entering the war in August, the Soviet government joined the Allied position.

The Cairo Declaration of 1943 had also addressed Japan’s territorial future, but it was not the final surrender demand. The Yalta Agreement concerned major Allied arrangements, including Soviet commitments in the war against Japan. Japan eventually accepted the Potsdam terms, leading to the August announcement and September signing.
