The narrowest part of the strait is in the west between Russia's Cape Krillion and Japan's Cape Sōya, which is also the shallowest at only 60 metres (197 ft) deep.[1] A small rocky island, appropriately named Kamen Opasnosti (Russian for "Rock of Danger") is located in the Russian waters in the northeastern part of the strait, 8 miles (13 km) southeast of the Cape Krillion. Another small island, Bentenjima, lies near the Japanese shore of the strait.
