Learn more about Kunashir Island
Kunashir Island (Кунашир (Kunashir) in Russian, 国後島:Kunashiri in Japanese, Black Island in Ainu language) is the southernmost island in the Kuril chain in Russia's Sakhalin Oblast. It is one of the islands in the Kuril chain which are claimed by Japan (see Kuril Islands dispute).
Kunashir is formed by four volcanoes which were separate islands but have since joined together by low-lying areas with lakes and hot springs. All these volcanoes are still active: Tyatya (1819 m), Smirnov, Mendeleev and Golovnin).
The island is formed with the volcanic and crystalline rocks. The climate is of monsoon type. The vegetation mostly consists of spruce, pine, fir, and mixed deciduous forests with lianas and Kuril bamboo underbrush. The mountains are covered with birch and Siberian Dwarf Pine scrub, herbaceous flowers or bare rocks.
