# Shiroishi Yuzawa Onsen

Northeast of Shiroishi city, along Route 113, the mountains close in gradually. The bus runs only on weekdays, and the ride takes the better part of an hour. By the time you arrive at Yakusen, the single inn that constitutes this onsen, the distance from anywhere familiar feels earned rather than calculated.

The waters here are of a particular kind — a gypsum and mirabilite spring, drawn directly from the source and allowed to flow without recirculation. What is rarer still is that these waters can be drunk. A licensed drinking fountain stands on the premises, permitted by the local health authority, and the act of swallowing the water rather than merely soaking in it shifts something in one's sense of what a hot spring can be. The body becomes less a surface to be warmed and more a vessel being attended to from within. There are no outdoor baths, only an indoor room where the water arrives and leaves without interruption.

To stay here for several nights is to enter a particular kind of quiet. There is one inn, one source, one road in. The rhythm settles quickly — mornings in the bath, afternoons perhaps walking the surrounding hills, evenings with little to do but return to the water. Yakusen holds to an older idea of what it means to take the waters: not as an amenity added to a stay, but as the reason for being there at all.
