The Empire of Japan (大日本帝國 Dai Nippon Teikoku, literally "Greater Japanese Empire") was the historical Japanese nation-state and great power that existed from the Meiji Restoration in 1868 to the enactment of the 1947 constitution of modern Japan.
Imperial Japan's rapid industrialization and militarization under the slogan Fukoku Kyōhei (富國強兵, "Enrich the Country, Strengthen the Armed Forces") led to its emergence as a world power and the establishment of a colonial empire. Economic and political turmoil in the 1920s led to the rise of militarism, eventually culminating in Japan's conquest of a large part of the Asia-Pacific region.
The Emperors during this time, which spanned the entire Meiji and Taishō, and the lesser part of the Shōwa eras, are now known in Japan by their posthumous name, which coincide with those era names: Emperor Meiji (Mutsuhito), Emperor Taishō (Yoshihito), and Emperor Shōwa (Hirohito).
