Imakane, on the Sea of Japan coast of southern Hokkaido in the Hiyama subprefecture, is a small fishing community in the coastal hills between the Esashi herring port and the Setana marine coast, whose traditional kombu kelp harvesting culture — Hokkaido produces the vast majority of Japan's kombu supply, the essential basis of Japanese dashi stock — creates a distinctive culinary maritime identity in this rural coastal community. Imakane Onsen Hokkaido draws on sodium and bicarbonate thermal waters from the geothermal resources of the Hiyama coastal zone, offering restorative baths in a small coastal community whose traditional kombu kelp harvesting heritage, the Sea of Japan coastal scenery, and the rural Hokkaido fishing village atmosphere create a genuinely unhurried and authentically maritime spa experience on the outer Hokkaido coast. The traditional Hokkaido kombu kelp harvesting and drying culture visible along the coastal road, the fresh Sea of Japan seafood of the Imakane fishing cooperative, and the coastal highland scenery of the Hiyama subprefecture's rugged Sea of Japan coastline create a pleasantly authentic and culinarily distinctive coastal spa destination in southern Hokkaido.
