The geographical location of the Japanese archipelago has defined the Sea of Japan for millions of years. Without the Japanese archipelago it would just be the Pacific Ocean. The term has been the international standard since at least the early 19th century. The International Hydrographic Organization, the international governing body for the naming bodies of water around the world, in 2012 recognized the term "Sea of Japan" as the only title for the sea.
