History of Japan
However, on August 6, 1945, the US dropped an atomic bomb over Hiroshima, killing over 90,000 people. This was the first nuclear attack in history. On August 9 the Soviet Union declared war on Japan and invaded Manchukuo, and Nagasaki was struck by a second atomic bomb. The unconditional surrender of Japan was announced by Emperor Hirohito and communicated to the Allies on August 14, and broadcast on national radio on the following day, marking the end of Imperial Japan's ultranationalist ideology, and was a major turning point in Japanese history.
