The East China Sea

The East China Sea is a marginal sea of the Western Pacific Ocean, located directly offshore from East China.

The East China Sea is bounded in the east and southeast by the middle portion of the first island chain off the eastern Eurasian continental mainland, including the Japanese island of Kyushu and the Ryukyu Islands, and in the south by the island of Taiwan. It connects with the Sea of Japan in the northeast through the Korea Strait, the South China Sea in the southwest via the Taiwan Strait, and the Philippine Sea in the southeast via gaps between the various Ryukyu Islands. Most of the East China Sea is shallow.

The Korean peninsula, China, Japan, and Taiwan lie within or border the East China Sea.
