The Empire of Japan, also known as the Japanese Empire or Imperial Japan, was the Japanese nation-state that existed from the Meiji Restoration on 3 January 1868 until the Constitution of Japan took effect on 3 May 1947. From 1910 to 1945, it included the Japanese archipelago, the Kurils, Karafuto, Korea, and Taiwan. Concessions such as the Kwantung Leased Territory were de jure not parts of the empire but dependent territories. In the closing stages of World War II, with Japan defeated alongside the rest of the Axis powers, the formalized surrender was issued on 2 September 1945 in compliance with the Potsdam Declaration of the Allies, and the empire's territory subsequently shrunk to cover only the Japanese archipelago resembling modern Japan.
