The Japanese established a settlement, Kashiwabara, on the site of the largest Ainu village (Ottomai), which became the major port on the island, and a center for the commercial fishing industry, particularly for herring.
During World War II Kashiwabara was strongly garrisoned by the Imperial Japanese Army and served as the headquarters of the IJA 91st Infantry Division.
Kashiwabara Airfield was established in the outskirts of the village, and numerous fortifications and gun emplacements were built.
The Soviets forcibly deported the remaining Japanese civilian inhabitants and sent the prisoners of war to labor camps.
Kashiwabara was renamed Severo-Kurilsk (Northern Kuril Town) and the island annexed by the Soviet Union in 1946.
Based on the tourism score, the best time of year to visit Severo-Kurilsk for warm-weather activities is for the entire month of August.
