Obama Onsen / Saichi no Yu, located in Ōda, Shimane Prefecture, has sodium-chloride water at 41°C. The facility offers an indoor bath, an outdoor rotenburo, and a sauna.
Insider tip — Saichi no Yu serves Ōda City, gateway to the Iwami Ginzan UNESCO World Heritage silver mine that produced up to one-third of global silver output in the 16th and 17th centuries. The mineral-rich geology that generated the Iwami silver deposits also feeds the coastal hot springs of this Shimane district, where the volcanic and tectonic forces that built Japan riches in metal and hot water share the same ancient geological foundation.
