On what date did Japan announce its surrender in 1945, according to Japanese local time?

Japan announced its surrender on August 15, 1945, according to Japanese local time.

Emperor Hirohito announced Japan’s acceptance of the Potsdam Declaration in a nationwide radio broadcast at noon Japan Standard Time. The announcement followed the atomic bombings of Hiroshima and Nagasaki, the Soviet entry into the war against Japan, and intense debate within the Japanese government.

The date can cause confusion because the announcement occurred on August 14 in the United States and some other places west of the International Date Line. The formal surrender ceremony came later, on September 2, 1945, when Japanese representatives signed the surrender document aboard USS Missouri in Tokyo Bay.

Japan commonly refers to August 15 as the day commemorating the end of the war, although the official Japanese name emphasizes mourning for the war dead and praying for peace. In the United States, V-J Day is also associated with September 2, the date of the formal signing.
