How & When the Japanese Surrendered?

Japan accepted the unconditional surrender.

On August 6, 1945, the United States dropped an atomic bomb on the city of Hiroshima.August 9, 1945, the Soviet Union invaded the Imperial Japanese puppet state of Manchukuo. Later that day, the United States dropped another atomic bomb, this time on the city of Nagasaki. The combined shock of these events caused Emperor Hirohito to intervene and order the Big Six to accept the terms for ending the war that the Allies had set down in the Potsdam Declaration On 15 August, Japan announced its surrender. The formal signing of the surrender instrument was held at City Hall, Singapore, then known as "Municipal Hall", on 12 September. This was followed by a celebration at the Padang, which included a victory parade.
