Kasumi no Sato Onsen, in Sakai (Fukui prefecture), uses sodium-chloride water heated to 41°C. The rural facility features an indoor bath, an outdoor rotenburo bath, and a sauna.
Insider tip — Kasumi no Sato Onsen, the spring mist village, serves the inland agricultural district of Sakai City, Fukui, where the Echizen plain gives way to the foothills of the Tamba highlands. The Echizen region of Fukui is one of Japan five great traditional washi paper districts — the Echizen washi tradition dating from the 6th century when the paper-making craft was brought from Korea — and the Imadate area surrounding this spring preserves active paper mills producing handmade washi of a quality that supplies the Imperial Household Agency and national art restoration projects.
