The Sea of Japan is located between Japan and Korea, along the northeast section of the continent of Asia. It is separated by the Tsushima and Korea Straights to the south near the East China Sea and by the Tatar Straights to the north from the Sea of Okhotsk.
The area of water known as the Sea of Japan has never had one official name. It is known in various parts of the world as the Oriental Sea, the Sea of Korea, the Sea of Japan and the East Sea. However, this fact is contested by the Ministry of Foreign Affairs of Japan, which insists on Sea of Japan as the sole internationally established name.
The Sea of Japan has an area of 377,600 square miles. Its mean depth is 5,748 feet and its maximum depth is 12,276 feet. Japan divides the banks of the sea off the shore into groups, which consist of the Hakusan Banks, Sado Ridge, Okujiri Ridge, Wakasa Ridge and Oki Ridge.
