Hot Spring
# Miai Onsen
At the foot of the Asan Mountains, where Kagawa Prefecture edges toward the Tokushima border, the Doki River runs upstream through a narrow valley, and the land grows quieter with each kilometer. Miai Onsen sits in this stillness — not dramatically, but simply, as though the mountain had always expected something to be here. The spring itself is a cold mineral water, barely ten degrees, classified as a simple carbonated spring. There is no drama in that description, yet cold carbonated water rising from the earth carries its own quiet insistence. It does not announce itself.
The place is young by onsen standards. Miai Onsen came into being in 1988, and Yuzan-so Asan Kotona opened its doors only in 2017 — recent enough that one does not arrive burdened with centuries of expectation. The inn offers several different baths, and the water, warmed from its cold source, moves through each of them in its own time. A stay of several nights would likely settle into a particular rhythm: mornings with the sound of the river, afternoons in one bath and then another, evenings with the mountains growing dark beyond the window.
To reach Miai, one takes a bus from Kotohira Station and rides for thirty-five minutes into the hills. That interval is not inconvenience — it is preparation. The valley asks for a certain willingness to slow down, and the water, when one finally enters it, seems to confirm that the distance was worth the patience.
