| Higashi-Naruko Onsen National Health Resort | The Naruko Onsen-kyo area — Naruko, Higashi-Naruko, Kawatabi, Nakayamadaira, and Onikobe — was designated in its entirety as a Ministry of the Environment “National Health Resort Onsen” (Kokumin Hoyo Onsen-chi) in 2016. Higashi-Naruko Onsen in particular is a roughly 650-year-old toji (hot-spring cure) resort where long-stay guests still bathe and self-cater to recuperate. Ryokan Onuma, founded in the Meiji era and calling itself a “100-year cure inn,” keeps a shared kitchen in its dedicated toji wing, carrying on what its innkeeper calls “modern toji” today. Details |

Though the water emerges at only 39°C, it has long drawn cure guests as a treatment for nervous ailments. Listed in the Tohoku chapter of Tsuge Yoshiharu no Onsen. Details |
