Which 1945 Allied declaration contained the surrender terms Japan accepted before V-J Day?

The Potsdam Declaration contained the surrender terms Japan accepted before V-J Day.

The declaration was issued on July 26, 1945, by the United States, the United Kingdom, and China during the Potsdam Conference. It demanded Japan's unconditional surrender and outlined the consequences of continued resistance, including the disarmament of Japan, the removal of militarism, and Allied occupation until the stated objectives were achieved.

Japan's government initially did not accept the declaration. After the atomic bombings of Hiroshima and Nagasaki, the Soviet Union's entry into the war against Japan, and escalating military pressure, Japan decided to accept its terms. Emperor Hirohito announced that decision in his August 15 radio address.

The declaration is often confused with the Cairo Declaration of 1943, which addressed Allied aims concerning territories taken by Japan, or with the later Japanese Instrument of Surrender, which was the document actually signed on September 2. The Potsdam Declaration set out the political conditions; the Instrument of Surrender formally recorded Japan's capitulation.
