context_page_description: The Empire of Japan is a historical nation-state along with its colonies, protectorates, mandates, and other territories that existed from the Meiji Restoration in 1868 to the enactment of the 1947 constitution of modern Japan.
  Japan's rapid industrialization and militarization under the slogan Fukoku Kyōhei and Shokusan Kōgyō led to its emergence as a great power and the establishment of a colonial empire following the First Sino-Japanese War, the Boxer Rebellion, the Russo-Japanese War, and World War I. Economic and political turmoil in the 1920s led to the rise of militarism, nationalism and totalitarianism, eventually culminating in Japan's membership in the Axis alliance and the conquest of a large part of the Asia-Pacific in World War II.
  Japan's armed forces initially achieved large-scale military successes during the Second Sino-Japanese War and the Pacific War. However, after many Allied victories and following the Soviet Union's declaration of war against Japan on August 9, 1945, and subsequent invasion of Manchuria and other territories, and the atomic bombings of Hiroshima and Nagasaki, the Empire surrendered to the Allies on August 15, 1945.
