Hirohito
The emperor, war and Japan’s changing state
Emperor of Japan 1926–1989
Hirohito was Japan’s emperor throughout the wars in China and the Pacific. In December 1941 he formally sanctioned the government’s decision for war against the United States and its allies; in August 1945 he announced surrender. He remained on the throne during occupation, while the postwar constitution changed his position.
Emperor and government were distinct
Hirohito became regent in 1921 and succeeded his father as emperor in 1926. Japanese expansion unfolded during his reign. His office should be distinguished from the cabinet and military commands: Tōjō, for example, held the office of prime minister.
War and responsibility
On 1 December 1941 Hirohito formally sanctioned the government’s decision for war against the United States and its allies.
Historians dispute the degree of his involvement in military strategy and war crimes. Neither an unqualified portrait of a powerless figurehead nor a claim that he personally directed every Japanese action adequately represents that question.
Surrender and a continuing monarchy
He announced surrender in a radio broadcast on 15 August 1945. He was not prosecuted at the postwar Tokyo tribunal. The constitution that took effect in 1947 defined the emperor as the symbol of the state and national unity.
His story therefore combines continuity on the throne with a transformed political system. The end of the war did not simply abolish the imperial office.
