Arima Onsen

One way to reach Arima is to take the Hankyu Line to Rokko Station, ride the Rokko Cable Car for ten minutes up through the pine forest to the summit plateau, cross the top of Mount Rokko on a winding bus road, and then drop down the far side on the Arima Ropeway in twelve minutes. When the gondola emerges from the trees and the old tile rooftops of the village come into view below you, the fact that you are less than an hour from central Kobe feels almost impossible. Arima sits in a steep-sided valley that cuts it off completely from the surrounding city, and that isolation is exactly why it has survived as a genuine hot spring town rather than a theme park version of one.

Arima is famous for having two entirely different kinds of water, and the difference between them is not subtle. The kinsen, or gold spring, arrives at the surface as a clear liquid but oxidizes almost immediately on contact with air, turning into a thick, reddish-brown water that looks like diluted rust. It is loaded with iron and sodium chloride, and when you lower yourself into a kinsen bath your skin is immediately coated with a faint mineral film, almost like being wrapped in warm salt air. The color stains the tiles and the stones a deep orange-brown over time, which gives the older bathhouses a patina that no amount of cleaning will remove. The ginsen, by contrast, stays clear, carries radium and carbonate, and produces a cool, fizzy sensation on the skin that feels completely different from the heavy warmth of the gold water.

The main public facility, Kin no Yu, is a low, plain building near the center of the village that has been in operation for a very long time. You pay a few hundred yen, leave your shoes in a cubby by the door, and join whoever is already in the cloudy brown water. Tosen Shrine, which guards the gods said to have discovered the springs, sits a short walk uphill and is the kind of small, shaded place that deserves ten quiet minutes even if you are not religious. The narrow shopping street between them sells ginger sweets that Hideyoshi Toyotomi supposedly requested on his visits in the sixteenth century, a detail that is probably embellished but is also probably at least partly true.

On winter evenings, when the temperature drops sharply in the valley, the red lanterns along the main street reflect in the wet stone paving and the steam rises from every drain and gutter. Standing at the edge of the public bath with the iron-brown water steaming in front of you, looking out through the wooden lattice at the dark hillside above the town, you understand why this place has been drawing visitors for well over a thousand years. It is not comfortable in a modern hotel sense. It is comfortable in a much older and more reliable way.
