"Iturup (Russian: and O , Ostrov Iturup; Ainu: , Etuworop-sir; Japanese: , Etorofu-t) is one of the Kuril Islands. It is the largest and northernmost island in the southern Kurils, which are disputed between Japan and Russia. The island was Japanese territory until the end of the Second World War in 1945, when Soviet forces took possession of all the Kurils and forced out Japanese residents. The island is still claimed by Japan (see Kuril Islands dispute). Japan considers a site on Iturup to be its northernmost point. Iturup is located near the southern end of the Kuril chain, between Kunashiri (19 km to the SW) and Urup (37 km to the NE). The town of Kurilsk, administrative center of Kurilsky District, is located roughly midway along its western shore. * Area 3,139 km² * Length 200 km * Width 727 km The strait between Iturup and Urup is known as the Vries Strait, after Dutch explorer Maarten Gerritsz Vries, the first recorded European to explore the area."
