Misplaced Pages

This is a list of regions occupied or annexed by the Empire of Japan until 1945, the year of the end of World War II in Asia, after the surrender of Japan. Control over all territories except most of the Japanese mainland (Hokkaido, Honshu, Kyushu, Shikoku, and some 6,000 small surrounding islands) was renounced by Japan in the unconditional surrender after World War II and the Treaty of San Francisco. A number of territories occupied by the United States after 1945 were returned to Japan, but there are still a number of disputed territories between Japan and Russia (the Kuril Islands dispute), South Korea and North Korea (the Liancourt Rocks dispute), the People's Republic of China and Taiwan (the Senkaku Islands dispute).
