Hirohito (29 April 1901 – 7 January 1989), posthumously known in Japan as Emperor Shōwa (昭和天皇), was the 124th Emperor of Japan, reigning from 25 December 1926 until his death. His 62-year reign — the Shōwa era — spans Japan's militarist expansion, defeat in World War II, the U.S.-led Occupation, and the country's postwar economic rise.
Under the Meiji Constitution of 1889, Hirohito was formally the supreme commander of the armed forces and a sacred, inviolable sovereign. The extent of his personal responsibility for wartime decisions — including the invasion of Manchuria (1931), the war with China from 1937, the attack on Pearl Harbor (7 December 1941), and atrocities such as those at Nanjing — remains contested among historians. Works by Herbert Bix (Hirohito and the Making of Modern Japan, 2000) argue he was an active participant in war policy, while earlier accounts portrayed him as a constitutional monarch constrained by his ministers and the military.
On 15 August 1945, Hirohito personally announced Japan's acceptance of the Potsdam Declaration in the Gyokuon-hōsō radio broadcast, the first time most Japanese had heard his voice. General Douglas MacArthur and the Supreme Commander for the Allied Powers (SCAP) chose not to prosecute him at the International Military Tribunal for the Far East (1946–48), a decision viewed as instrumental for stabilising the Occupation but criticised by other Allied governments, notably Australia and the Soviet Union.
On 1 January 1946, Hirohito issued the Ningen-sengen ("Humanity Declaration"), repudiating the claim of imperial divinity. The 1947 Constitution of Japan redefined the emperor as "the symbol of the State and of the unity of the People" (Article 1) with no governing powers. He undertook landmark state visits, including to Western Europe in 1971 and the United States in 1975, meeting President Gerald Ford. He was succeeded by his son Akihito, beginning the Heisei era.

Frequently asked questions
No. General MacArthur and SCAP excluded him from prosecution at the Tokyo Tribunal (1946–48), judging that retaining the emperor would aid the Occupation, despite objections from several Allied states.
