Hirohito (1901–1989), posthumously known as Emperor Shōwa, was Emperor of Japan from 1926 until his death in 1989. His reign covered Japan’s militarist expansion, World War II, and the postwar transformation of the monarchy into a largely symbolic institution. He was the longest-reigning monarch in Japanese history.

Early life and accession

Hirohito was born in Tokyo on 29 April 1901 as the eldest son of Crown Prince Yoshihito. He became emperor on 25 December 1926 and was later given the era name Shōwa, meaning "enlightened peace."

Reign during World War II

Hirohito’s reign coincided with Japan’s rise in militarism and its entry into World War II. Historians continue to debate the extent of his responsibility and authority in wartime decisions.

Postwar role

After Japan’s surrender, Hirohito remained emperor under the new constitutional system. The monarchy’s role changed from imperial rule to a symbolic institution, while he continued ceremonial duties until his death.
