Which 1945 declaration did Japan agree to accept before formally surrendering?

Japan agreed to accept the Potsdam Declaration before formally surrendering in 1945.

The declaration was issued on July 26, 1945, by the United States, the United Kingdom, and China. It demanded Japan’s unconditional surrender and laid out broad conditions for ending the war, including the removal of Japanese militarism and occupation of territory designated by the Allies.

The Soviet Union was not an original signatory because it was still neutral toward Japan when the declaration was issued. After the Soviet Union declared war on Japan on August 8, it joined the Allied position.

Japan’s government announced its acceptance in August, while seeking a condition concerning the imperial institution. The Allies then proceeded with the formal surrender ceremony aboard USS Missouri on September 2. The Potsdam Declaration is sometimes confused with the Cairo Declaration, which had been issued in 1943 and addressed Allied aims in East Asia.
