About 73% of Japan is mountainous, with a mountain range running through each of the main islands. Japan's highest mountain is Mount Fuji, with an elevation of 3,776 m (12,388 ft). The mountainous islands of the Japanese archipelago form a crescent off the eastern coast of Asia. They are separated from the mainland by the Sea of Japan, which historically served as a protective barrier.
