Which 1945 declaration set the terms Japan was required to accept when surrendering?

The Potsdam Declaration set the terms Japan was required to accept when surrendering.

The declaration was issued on July 26, 1945, by the United States, the United Kingdom, and China during the final stage of World War II. It demanded Japan's unconditional surrender and warned of “prompt and utter destruction” if Japan refused.

The document called for the elimination of Japanese militarism, occupation of designated Japanese territory, disarmament of the armed forces, and prosecution of war criminals. It also stated that Japan would not be permanently destroyed as a nation and that its people could eventually enjoy peaceful self-government.

After the atomic bombing of Hiroshima, the Soviet declaration of war, and the bombing of Nagasaki, Japan accepted the declaration's terms. Hirohito's surrender broadcast referred to it as the joint declaration accepted by the Japanese government.
