is an era of Japanese history which extended from October 23, 1868 to July 30, 1912. This era represents the first half of the Empire of Japan, during which period the Japanese people moved from being an isolated feudal society at risk of colonisation by European powers to the new paradigm of a modern, industrialised nation state and emergent great power, influenced by Western scientific, technological, philosophical, political, legal, and aesthetic ideas. As a result of such wholesale adoption of radically-different ideas, the changes to Japan were profound, and affected its social structure, internal politics, economy, military, and foreign relations. The period corresponded to the reign of Emperor Meiji. It was preceded by the Keiō era and was succeeded by the Taishō era, upon the accession of Emperor Taishō.
