The Shōwa era was the period of Japanese history corresponding to the reign of Emperor Shōwa from December 25, 1926, until his death on January 7, 1989. It was preceded by the Taishō era and succeeded by the Heisei era.
The pre-1945 and post-war Shōwa periods are almost completely different states: the pre-1945 Shōwa era (1926–1945) concerns the Empire of Japan, and post-1945 Shōwa era (1945–1989) concerns the State of Japan.
