The Korea Strait is a sea passage in East Asia between the Korean Peninsula and Japan.
It connects the East China Sea, the Yellow Sea and the Sea of Japan in the northwest Pacific Ocean.
The strait is split by Tsushima Island into two parts: 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 South Korea allow free passage through it.
