Which declaration did Japan accept when announcing its surrender in August 1945?

Japan accepted the Potsdam Declaration when it announced its surrender in August 1945.

The declaration was issued on July 26, 1945, by the United States, the United Kingdom, and China during the final phase of World War II. It demanded Japan's unconditional surrender and outlined broad Allied objectives, including the elimination of Japanese militarism and the occupation of territory specified by the Allies.

The Soviet Union was not an original signatory because it was still bound by its neutrality agreement with Japan. After the Soviet Union entered the war against Japan in August, it joined the declaration's position.

Hirohito's broadcast said that the Japanese government had accepted the provisions of the joint declaration. The wording was indirect, which caused some listeners to miss that it meant Japan had surrendered. The formal Instrument of Surrender later documented that acceptance.
