Sea of Japan

The Sea of Japan is a marginal sea set off from the Pacific Ocean by the Japanese Archipelago, the Korean Peninsula, the Sakhalin Islands, and Russia. Due to its inclusion by these land masses, it has practically no tide changes. Very few rivers empty into it, and their water amounts to less than one percent of the sea’s content. The sea’s salinity is less than the adjacent Pacific as well. In the geologic past, the Sea of Japan was a landlocked body of water. The Sea of Japan has no large islands, bays or capes.
