Rishirifuji Onsen is located in Rishirifuji, on Rishiri Island off Hokkaido, dominated by its cone-shaped volcano. Sodium-chloride water reaches 41°C, shared between an indoor bath, an outdoor rotenburo bath and a sauna.
Insider tip — On the eastern flank of Rishiri Island facing the perfect cone of Mount Rishiri (Rishiri-Fuji), this community onsen serves the Rishirifuji port town where kelp fishing boats return with the finest rishiri kombu in Japan; the volcanic mountain, wild northern sea, and mineral spring form a trinity of natural abundance unique to this remote sub-Arctic island.
