A precious private spring that has been continuously gushing from a limestone cave in the mountains behind the inn for several hundred years is used exactly as it is, as 100% free-flowing hot spring water with no heating, dilution, circulation, or disinfection at all. It is characterized by a faint sulfur scent and dancing hot-spring minerals, has a high alkaline content, and feels exceptionally soft and smooth on the skin. From the open, roofless outdoor bath, you can take in the unobstructed beautiful townscape of Yuzawa and a sweeping panorama of the Tanigawa mountain range, enjoying blissful hot spring bathing together with the natural breeze.

A private Suwa spring that can be enjoyed in guest rooms with an onsen open-air bath in the Yunosaka Wing. With a different water quality from the large public bath, it contains salt and therefore has outstanding heat-retaining effects, keeping you warm long after bathing. This fresh spring water, gushing at 57 degrees, is used as free-flowing hot spring water with no dilution or heating whatsoever, with only the volume adjusted, allowing you to fully savor a luxurious second famous spring in a private space with spectacular views.
