This rocky coast consists of 30-million-year-old granite formed in the era when the Japanese archipelago was part of the continent and the Sea of Japan did not exist. The rough wave of the Sea of Japan and winter winds erode the granite rocks along fracture and faults, creating the unique coastal terrain of coastal caverns, boulders, and coastal platforms.
