Before World War II, Japan owned this chain of four islands located between Russia (south of the Kamchatka Peninsula) and Japan (north of Hokkaido). During the war, the then-Soviet Union took control of the islands and hasn’t given them back. Japan has been requesting their return, but to no avail. Because of the Kurile Island controversy, Japan has yet to sign a peace treaty with Russia declaring the end of World War II.
