The Sea of Okhotsk is a marginal sea of the western Pacific Ocean, lying between the Kamchatka Peninsula on the east, the Kuril Islands on the southeast, the island of Hokkaido to the far south, the island of Sakhalin along the west, and a long stretch of eastern Siberia coast (including the Shantar Islands) along the west and north. The northeast corner is Shelikhov Gulf. It is named after Okhotsk, the first Russian settlement in the Russian Far East.
