What was the name of the Allied declaration Japan accepted before surrendering in 1945?

The Potsdam Declaration was the Allied declaration Japan accepted before surrendering in 1945.

The United States, the United Kingdom, and China issued the declaration on July 26, 1945, during the Potsdam Conference. It called for Japan’s unconditional surrender and warned of “prompt and utter destruction” if Japan refused.

The declaration outlined major postwar conditions, including the disarmament of Japanese forces, the occupation of selected Japanese territory, and limits on Japan’s sovereignty. It also promised that the Japanese people would not be enslaved or destroyed as a nation.

Japan initially did not accept the declaration publicly. After the atomic bombings of Hiroshima and Nagasaki, the Soviet declaration of war, and internal political debate, Emperor Hirohito supported acceptance. Japan then announced surrender on August 15, while the formal instrument was signed on September 2.
