Kawayu Onsen

Overview

Kawayu Onsen is a rustic hot spring nestled along the banks of the Oto River, a tributary of the Kumano River. Known for its alkaline simple hot spring waters (73°C), it's believed to alleviate nerve pain, skin conditions, and diabetes. A unique feature is the ability to dig your own open-air bath in the riverbed. From December to late February, experience the Sennin-buro, a giant open-air bath in the Oto River. Enjoy the sounds of the river by day or stargaze at night while soaking in the hot spring.
