Towa Onsen, in Hanamaki, Iwate prefecture, offers sodium-chloride water at 41°C. The facility features an indoor bath, an outdoor rotenburo bath and a sauna.
Insider tip — In Hanamaki, birthplace of visionary poet and agronomist Kenji Miyazawa whose Night on the Galactic Railroad remains one of Japan's most beloved children's stories, Towa Onsen (eternal spring) celebrates the flowers (hana), greenery (midori), and relaxation (yasuragi) that Miyazawa saw as essential to human happiness; visiting his museum and memorial park, then soaking in Towa's mineral waters, creates a perfect literary pilgrimage day in Iwate.
