What was the name of the 1945 Allied declaration whose terms Japan accepted when it surrendered?

Japan accepted the Potsdam Declaration when it surrendered in 1945.

The declaration was issued on July 26, 1945, by the United States, the United Kingdom, and China. It demanded the unconditional surrender of Japan's armed forces and warned of “prompt and utter destruction” if Japan refused. The Soviet Union was not initially a signatory because it was still neutral in its relations with Japan at that moment.

The document also outlined broad Allied aims, including the removal of militarism, occupation of Japanese territory, and limitation of Japanese sovereignty to the home islands and other areas determined by the Allies. It promised that Japan would not be destroyed as a nation, but required the elimination of militaristic influence.

After the atomic bombings and the Soviet Union's entry into the war against Japan, the Japanese government accepted the declaration's terms. Hirohito's August 15 broadcast announced that decision, while the September 2 ceremony formalized it.
