Ichinoseki Onsen Negaikano no Yu is in the city of Ichinoseki, Iwate Prefecture. The iron-rich water emerges at 41°C, pH 6.3. Amenities include an indoor bath, an outdoor rotenburo and a sauna.
Insider tip — Negaikano no Yu draws iron-laden waters from deep below the Kitakami basin, giving the bath a warm amber hue and a gentle metallic tang. The spring is said to invigorate circulation and ease muscle fatigue after long hikes in the nearby Geibikei gorge. Early morning sessions are especially prized when mist rolls off the river and the bathhouse is nearly empty. The facility also offers traditional tatami rest rooms where guests can nap between soaks.
