Tagadai Onsen (Takumi no Yu), also in Hachinohe, Aomori, offers sodium-chloride water at 41°C, split between an indoor bath and an outdoor rotenburo, with a sauna.
Insider tip — Takumi no Yu (artisan's waters) at Tagadai Onsen celebrates the craftsmanship traditions of the Hachinohe area, famous for its Hachinohe lacquerware and Nambu ironware heritage; the mineral waters that restore artisans' hands and bodies are as integral to the craft culture of this Aomori port city as the workshops and kilns where traditional skills are passed between generations.
