Senbonmatsu Onsen is located in Nasushiobara, Tochigi Prefecture, a mountainous region north of Tokyo. The sulfurous water reaches 44°C, pH 6.5. An indoor bath, an outdoor rotenburo bath and a sauna are available.
Insider tip — Senbonmatsu Onsen, the thousand pine trees spring, is embedded in the legendary Senbonmatsu Farm, a Meiji-era model ranch developed by government ministers as a showcase for Western-style agriculture on the Nasu Plateau. The famous pine-tree avenue stretching through the pastoral estate is one of Tochigi most photographed landscapes, and the spring complex serves both the farm heritage visitors and the sulfurous Shiobara volcanic tourism district nearby.
