Korea Strait

Sea passage between Japan and South Korea

The Korea Strait is a sea passage in East Asia between Korea and Japan, connecting the East China Sea, the Yellow Sea and the Sea of Japan in the northwest Pacific Ocean. The strait is split by the Tsushima Island into the Western Channel and the Tsushima Strait or Eastern Channel. It is economically important, as many shipping lanes pass through the strait, and both Japan and Korea permit free passage through it. In ancient times, both Buddhism and Mongol invaders passed over the strait to reach Japan. More recently, it was the site of the Battle of Korea Strait in the Korean War. A tunnel running underneath the strait connecting Japan and Korea, the Japan–Korea Undersea Tunnel, has been proposed to connect the two countries.
