Nagaoka Onsen
TypeNatural Hot Spring
A natural sodium chloride hot spring that wells up from 1200 meters underground. The water is weakly alkaline at pH8.6 and is known to remove excess keratin from the skin, leaving it smooth after bathing, earning a reputation as a 'beauty hot spring'. The water is mild with a silky texture and low irritation. You can relax in the hexagonal outdoor bath while viewing the rock garden, and fully enjoy the hot spring's benefits in a variety of baths such as utase-yu (cascading waterfall bath) and bubble baths.
