The Mitsuma River moves through Hita with a patience that seems to set the tempo of the whole town. Along its banks, a small cluster of inns — eight or so, gathered around Konnya-cho and the surrounding streets — constitutes the onsen district. The waters here are relatively recent by Japanese standards, surfacing in the modern era rather than in some deep historical past, which gives the place an unpretentious quality. Nothing here insists on its own antiquity. The springs themselves run as simple alkaline waters and chloride springs, and at one inn situated on a river island — 日田天領水の宿 — the water carries sodium bicarbonate alongside the chloride, a combination that leaves the skin feeling gently altered, as though something has quietly been given back to it.

To stay several nights here is to settle into the river's rhythm. The Mitsuma is not incidental to the experience; it is the experience. A room that faces the water means waking to its sound, stepping into the bath with that same current somewhere below you. In late May, the river opens its season formally — fireworks rise above the water during the Kawabiraki festival — but even outside that moment, the riverbank holds a particular quality of attentiveness.

What remains, after the festival and the cormorant boats, is the town itself: modest, unhurried, living beside water the way towns in this part of Oita simply do. Hita is not a place that performs its appeal. It asks for time, and in return offers the sensation of having genuinely paused somewhere.
