Namiki Onsen Yu no Sato, also in Kōriyama (Fukushima), has sodium-chloride water at 41°C, across an indoor bath, an open-air outdoor bath and a sauna.
Insider tip — Namiki, the tree-lined avenue spring, sits in Koriyama along the rows of zelkova trees that line the old roads of this Fukushima commercial hub. Lake Inawashiro and the Bandai Highland, both easily accessible, provide spectacular scenery for those who want nature after their urban soak.
