Yagoshima Onsen, known as Sato no Yu, is located in Shimogo, Fukushima Prefecture. Its sodium-chloride thermal water reaches around 40°C (pH 7.3), with an indoor bath, an outdoor rotenburo and a sauna.
Insider tip — Shimogo-machi is home to one of Japan's most iconic historic sites: Ouchi-juku — a perfectly preserved Edo-period post town where thatched-roof inns line the main road as they have for 400 years, deep in a snow-covered mountain valley. The village is one of Japan's 'Important Preservation Districts' — unchanged, unchanged, and in winter buried under 1.5 meters of snow that turns the entire townscape into a fairytale. Yagoshima Onsen's Sato no Yu provides a warm community bath for the mountain villages of this remarkable valley of living history.
