Free-flow from source
Mamejima Onsen
The facility's private source from the abundantly flowing Mamejima Onsen. This chloride spring contains sodium and calcium, offers exceptionally strong heat retention, and warms your body all the way to the core. It is also a mildly alkaline, skin-friendly bath with metasilicic acid, making it a skin-beautifying hot spring. You can fully enjoy the fresh spring quality directly in the free-flowing natural spring bath and the natural spring pot bath, where the source water overflows luxuriously as it is.
