Assabu, on the Sea of Japan coast of the Hiyama subprefecture of Hokkaido between Setana and Esashi, is a remote coastal community in the rugged hills facing the outer Sea of Japan where traditional fishing for kelp, sea urchin, and abalone has sustained the community across generations in one of Hokkaido's more isolated coastal districts, its quiet character reflecting the unhurried pace of Hokkaido's outer coastal communities. Assabu Onsen Hokkaido draws on chloride-rich coastal thermal waters from the marine geological formations of the Assabu Bay coast, providing warming maritime baths in a remote coastal community whose quiet fishing village atmosphere, traditional kelp and shellfish harvesting culture, and the rugged Sea of Japan coastal scenery create an authentically isolated and atmospheric spa setting on the outer Hokkaido coast. The traditional Assabu kombu and sea urchin coastal harvest culture, the rugged Sea of Japan cliff and cape scenery of the Hiyama outer coast, and the genuine rural Hokkaido fishing community atmosphere far from the developed Niseko resort zone create an appealingly remote and unhurried thermal destination on the less-visited southern Hokkaido coastal arc.
