219. Taki no Yu, Naruko Onsen An amazing public onsen. Entry is 300. Inside, a small room with two baths. Water is white, with that proper onsen sulfuric smell. The main bath is 45-46, the second smaller one is around 38. An excellent combo - first soak in the hot one, then relax in the mild one. Breathing inside is good. Photos of the bath from the internet match reality. In my opinion, a must-visit when in Naruko Onsen. I was thrilled with this onsen.
