Okushiri Island Onsen

Okushiri Island Onsen is a hot spring destination on Okushiri Island, a small, remote island in the Sea of Japan off the southwestern coast of Hokkaido, known for its pristine coastal scenery and the extraordinary recovery of its community after the devastating 1993 Okushiri earthquake and tsunami. The chloride sodium mineral waters emerging on the island are characteristic of the coastal geothermal systems of the Sea of Japan zone, offering warm, saltwater-influenced thermal bathing with the flavor of an island thermal experience far removed from mainland resort culture. The island's rugged coastline of sea stacks, caves, and dramatic rock formations, its abundant seafood, and the particular quietness that comes with island isolation make Okushiri a destination of genuine character and authenticity. Okushiri Island Onsen is a thermal experience for those who seek the combination of mineral water bathing and the elemental atmosphere of a remote Japanese island — a place where the Sea of Japan meets the earth's inner heat.
