Alkaline Simple Spring
A serene communal onsen bath paired with an open-air bath where a gentle breeze meets soothing waters — a restorative ritual for body and mind.

Our alkaline simple spring water, with a pH of 8.7, gently softens the outer layer of the skin much like soap does — a natural cleansing effect that leaves the skin smooth and supple. It is fondly known as the "Beauty Bath."
The sauna is said to support weight management, healthy-looking skin, recovery from fatigue, and stress relief. Please enjoy it — and listen to your body throughout your visit.
