Kawayu Onsen

Springing up along a clear stream that flows through the mountains of Kumano, Kawayu Onsen is known for the rare quality of hot water rising straight from the riverbed. The experience of digging up the river stones to instantly create your own private bath is hard to find anywhere else. Rustic bathing to the sound of the babbling current is the true delight of this place.

Highlights

Above all, the greatest attraction here is being able to dig your own bath in the riverbank by hand. Mixing the cold river water with the welling hot water to adjust the temperature to your liking is itself an enjoyable task. Time spent gazing at the clear river surface and the ranges of mountains gives a soothing sense of becoming one with nature.

Enjoying the Seasons

In the depths of cold winter, a large open-air bath made by damming part of the river becomes the local specialty and draws many visitors. In summer you can enjoy the waters alongside river play, savoring the luxury of moving between cool and warm. In the seasons of fresh green and autumn color, the hues of the mountains reflected on the water delight the eye.

Access and Basic Information

From the nearest railway station, a bus heads into the mountains to reach this riverside hot spring near the sacred sites of Kumano. Nearby springs such as Yunomine and Watarase are scattered close by, making it a convenient base for bath-hopping. Inns line the river, and many rooms look out over the clear stream.

A Quick Tip

To enjoy the riverbank baths, bringing clothes you dont mind getting wet and a change of clothing keeps things comfortable. The great winter open-air bath is offered only for a limited period, so it is wise to check the dates before visiting.
