Kunashir Island
is located on the easternmost portion of the Japanese island of Hokkaidō, protruding into the Sea of Okhotsk. It is separated from Kunashir Island, which is now occupied by Russia, by the Nemuro Strait. The name Shiretoko is derived from the Ainu word "sir etok", meaning "the end of the Earth" or "the place where the Earth protrudes". The towns of Rausu and Shari are found on the peninsula.
