Historical Map of East Asia & the Western Pacific

When Japan failed to respond to the bombing of Hiroshima, the US dropped a second bomb on Nagasaki. At the same time, the Soviet Union entered the war by invading Manchuria and Japan's northern islands. For the next two days, the Japanese government debated whether or not to continue the war, until the Emperor finally stepped in to break the deadlock. On August 15, he spoke to his people for the first time, via a radio broadcast, accepting the Allied terms and agreeing to unconditional surrender.
