Tsushima Strait

The Tsushima Strait (対馬海峡) is a strait between the Korean Peninsula and Kyushu, the furthest west of the four largest islands in Japan. Tsushima, in the middle of the Tsushima Strait, is an island near the Korean Peninsula in Japan. The sea between the Korean Peninsula and Tsushima is called the West Channel or Korea Strait. The sea between Tsushima and Kyushu is called the East Channel.

This strait connects the East China Sea and the Sea of Japan.

This sea serves as a stage for cultural exchange between Korea and Japan. Buddhism was transmitted from Korea to Japan through this strait. The Mongolian invasion of Japan crossed this sea and the Korean Allied Forces have attacked Japan through it. A decisive battle between the Japanese and Russian navies during the Russo-Japanese War also took place here. A ferry service operates between Busan and Shimonoseki now, and Korean and Japanese passengers are going back and forth.
