The evacuation of Karafuto (Sakhalin) and the Kuriles refers to the events that took place during the Pacific theater of World War II as the Japanese population left these areas, to August 1945 in the northwest of the main islands of Japan.
The evacuation started under the threat of Soviet invasion. As Japanese civilians evacuated Korea and Manchuria, they cleared out of the Karafuto and Kurile Islands according to the terms of the Potsdam Declaration that the terms of the Cairo Declaration would be carried out, and Japanese sovereignty would be limited to the Home Islands of Honshū, Hokkaidō, Kyushu, Shikoku and such minor islands as the Allies determined.
The operation began with the crossing of the Horonai (Poronai) Japanese frontier river post and bombardment of the Handenzawa Japanese land frontier post in Shikuka district, as well as the advance to the north of Koton (now Pobedino), a powerful fortified district (FD). Severe fighting with heavy losses on both sides continued for over a week, with Soviet troops breaking the Japanese defenses on August 18. The Soviets also landed their naval forces deep behind enemy frontlines to aid their ground forces.
According to some of the 6,000 refugees already evacuated from the area, Soviet forces carried out fierce naval bombardment and artillery strikes against civilians awaiting evacuation as well as Japanese installations in Maoka, Shikuka on August 10. Nearly 1,000 civilians were killed by machine-gun fire in this attack.Telephone operators in the city decided not to evacuate, instead maintaining contact with the Wakkanai and Mainland Japan until the moment that Soviet forces destroyed the telephone and postal installations in the city.
