Shortly before dawn on Aug. 15, 1945, a national broadcast alerted Japanese to expect a message from the emperor later that day. Across Japan, people waited in uncertainty to hear for the first time “the jeweled voice.” Most expected that the emperor would urge them on to fight to the end. What they heard was a high-pitched voice speaking in archaic Japanese that many could not comprehend. It was only after a commentator explained that the emperor had agreed to surrender that they knew for certain that the war was over.
When the news reached Washington, the celebrations began immediately. But the formal ceremony ending the war had to wait until Sunday, Sept. 2, 1945, when Japan’s official defeat was staged on the USS Missouri. The document signed by the representatives of the Allied Powers and Japan declared the unconditional surrender of the Imperial General Headquarters and all the armed forces under Japanese control. It also made the authority of the emperor and the Japanese government subject to U.S. General Douglas MacArthur’s orders and commanded all civil and military officers to obey him. At the ceremony’s conclusion, MacArthur moved to a microphone and began a radio address to a world audience. “Today the guns are silent,” began the now famous message. “A great tragedy has ended. A great victory has been won.”
Everything that followed—the disarmament of Japan, the reform of its economic, political, and social institutions, the adoption of a new constitution, and the surrender of Japan’s undefeated armies in China and Southeast Asia—followed from American influence on the emperor, who ordered the unconditional surrender of Japan’s armed forces. With planes soaring overhead and more than 200 ships of the 3rd Fleet stretched out across the bay, America’s might was everywhere in evidence. None of those present could have known that this was the last time Americans would stand as the indisputable victors in war, imposing their will on a conquered foe. The display of military power in Tokyo Bay was intended to awe the Japanese, but it also created a misleading impression of what could be achieved by force of arms.
