Omori Kenko Onsen is a hot spring bathhouse in Akita, in the eponymous prefecture. Its iron-rich water reaches 42°C and is split between an indoor bath and an outdoor rotenburo, with a sauna on site.
Insider tip — Omori Kenko Onsen is a health-focused hot spring facility in the Akita basin of northern Tohoku, drawing iron-rich waters from the deep volcanic substrata of this geothermally active prefecture. The amber-tinted iron-rich baths have a particularly warming, circulation-stimulating quality prized by Akita locals during the harsh snowy winters. The facility emphasizes the kenko (health and wellness) aspect of bathing with guided stretching areas and mineral water drinking stations. The cedar and stone interior design references traditional northern Japanese architecture and creates a meditative sensory environment.
