Kawatabi sits along the Araogawa River at the eastern edge of the Naruko cluster, and it is the oldest of the group — its waters recorded as far back as 837, its name appearing in the Engishiki of 927. For centuries it was known as the place for beriberi, a destination not of leisure but of recovery. Farmers and fishermen came here between seasons, settling into lodgings for days or weeks at a stretch, soaking in waters gentle enough to bear repeatedly. The phrase the locals used was *honeyasume no ba* — a place for resting the bones.

Seven inns and a shared public bath still line the south bank of the river. The scale is modest, almost domestic. Shōunji, a temple founded in 1508, anchors one end of the settlement; at the shrine called Onsen Ishigami, a ceremony each September offers the hot water itself as tribute, praying for the springs' continued generosity. Upstream, the site called Ogurosakii once drew poets of the imperial court, its name circulating through verse collections as a *utamakura* — a place that lived as much in language as in geography. These layers accumulate rather than announce themselves.

To stay here for several nights would be to feel the particular rhythm of a low-temperature spring: water you can sit in for a long time, that softens the body gradually rather than overwhelming it. The river is always audible. The inns are few enough that you begin to recognize the same faces at the communal bath. There is little to do in the conventional sense, which is precisely what generations of tired workers came here for. Kawatabi does not perform its history. It simply continues, quietly, along the riverbank, as it has for over a thousand years.
