Onsen
Waters of Aso
Water from a thousand metres down
An alkaline simple spring, run straight from the source — in the bath of each villa, and in the great open-air bath you can reserve.
Simple Alkaline Spring — "Beauty Water"
A soft, gentle bath with little skin irritation — the water leaves the skin smooth, gently exfoliating; locally known as the "water of beautiful skin."
