What was the final Allied declaration whose terms Japan accepted before surrendering in 1945?

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

Issued on 26 July 1945, the declaration demanded Japan’s unconditional surrender and outlined the consequences of continued resistance. It was issued by the United States, the United Kingdom, and China while Allied leaders met at Potsdam in Germany. The Soviet Union joined the war against Japan later and was not an original signatory to the declaration.

Japan initially rejected the declaration publicly, using the term mokusatsu, often translated as ignoring or withholding comment. After the atomic bombings, the Soviet declaration of war, and internal political debate, Japan accepted the terms. The Japanese Instrument of Surrender then formalized that acceptance on 2 September. The Cairo Declaration of 1943 also concerned Japan’s defeat and territorial disposition, but it was not the immediate surrender ultimatum.
