Fukushi no Sato Onsen, in Sarabetsu village on the island of Hokkaido, taps sodium-chloride thermal water at 40°C, with an indoor bath, an outdoor rotenburo and a sauna.
Insider tip — Sarabetsu-mura in the Tokachi Plain is one of Hokkaido's most productive dairy farming communities — vast rectangular fields of maize, beet, and pasture stretching to the horizon in a landscape unique in Japan for its North American agricultural scale. The Tokachi artesian aquifer delivers thermal waters that sustain this hard-working community through Hokkaido's harsh winters. The Tokachi Mountains, including Mt. Tokan, frame the eastern horizon; the dairy farms of the plain supply some of Japan's finest butter and cheese.
