The Shōwa era (昭和時代, Shōwa jidai; [ɕoːwadʑidai] ) was a period of Japanese history corresponding to the reign of Emperor Shōwa (Hirohito) 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 the post-1945 Shōwa era (1945–1989) concerns the modern-day Japan.
Before 1945, Japan moved into political totalitarianism, ultranationalism and statism, culminating in Japan's invasion of China in 1937, part of a global period of social upheavals and conflicts such as the Great Depression and the Pacific War.
