In the 18th cent. both Russians and Japanese claimed the islands (they are still known in Japan as the Northern Territories). In 1875, Japan gave up Sakhalin in return for Russian withdrawal from the Kuriles, and the Japanese held the islands until the end of World War II. The Yalta Conference ceded the islands to the USSR, and Soviet forces occupied the chain in Sept., 1945. Japan has challenged the Soviet (after 1991, Russian) right to the Kuriles, and demanded the return of the four southernmost islands, which had been treated as part of Hokkaido prior to World War II. The failure to resolve the impasse has been a major stumbling block in Russo-Japanese relations since the end of the war, leading at times to tensions.
