Nogi Onsen Hotel Yu no Sato, also in Nasushiobara, Tochigi Prefecture, heats sodium-chloride water to 41°C. The hotel has an indoor bath, an outdoor rotenburo pool and a sauna.
Insider tip — Yu no Sato serves the southern Nasushiobara area near the Nasu plateau where the imperial family summer residences cluster in the beech forests. The Nogi border area recalls General Nogi Maresuke who committed ritual suicide (junshi) on the death of Emperor Meiji in 1912 — a final act of samurai devotion that shocked Meiji Japan and marked the end of an era, now commemorated in the Nogi Shrine and gardens nearby.
