when did the allied occupation of japan end
Occupation of Japan In 1949, MacArthur made a sweeping change in the SCAP power structure that greatly increased the power of Japan's native rulers, and the occupation began to draw to a close. The Treaty of San Francisco, which was to end the occupation, was signed on September 8, 1951. It came into effect on April 28, 1952, formally ending all occupation powers of the Allied forces and restoring full sovereignty to Japan, except for the island chains of Iwo Jima and Okinawa, which the United States continued to hold. Iwo Jima was returned to Japan in 1968, and most of Okinawa was returned in 1972.
End of World War II in Asia The end of World War II in Asia occurred on 14 and 15 August 1945, when armed forces of the Empire of Japan surrendered to the forces of the Allies. The surrender came over three months after the surrender of the Axis forces in Europe and brought an end to World War II.
End of World War II in Europe The final battles of the European Theatre of World War II as well as the German surrender to the Soviet Union and the Western Allies took place in late April and early May 1945.
Surrender of Japan On August 6, 1945, at 8:15 AM local time, the United States detonated an atomic bomb over the Japanese city of Hiroshima. Sixteen hours later, American President Harry S. Truman called again for Japan's surrender, warning them to "expect a rain of ruin from the air, the like of which has never been seen on this earth." Late in the evening of August 8, 1945, in accordance with the Yalta agreements, but in violation of the Soviet–Japanese Neutrality Pact, the Soviet Union declared war on Japan, and soon after midnight on August 9, 1945, the Soviet Union invaded the Imperial Japanese puppet state of Manchukuo. Later in the day, the United States dropped a second atomic bomb, this time on the Japanese city of Nagasaki. Following these events, Emperor Hirohito intervened and ordered the Supreme Council for the Direction of the War to accept the terms the Allies had set down in the Potsdam Declaration for ending the war. After several more days of behind-the-scenes negotiations and a failed coup d'état, Emperor Hirohito gave a recorded radio address across the Empire on August 15. In the radio address, called the Jewel Voice Broadcast (玉音放送, Gyokuon-hōsō), he announced the surrender of Japan to the Allies.
