Kawayu Onsen Travel Tips

Kawayu Onsen (川湯温泉) is a one-of-a-kind hot spring town nestled along a picturesque river, where visitors can participate in the unique tradition of creating their own bath. By digging a hole in the gravel riverbank, guests allow the natural hot spring water to flow into their custom-made bath, blending with the cool river water to create a personalized experience. This lets each bather adjust the temperature to their liking, ensuring a relaxing and therapeutic soak. During the winter months, a giant rotenburo (outdoor bath) known as the Sennin Bath is created in the same way and is available for free public use. The experience of soaking in the open air, surrounded by winter scenery, offers a truly memorable and special way to enjoy the onsen.

Kawayu Onsen’s combination of natural beauty and soothing hot spring waters creates an unparalleled experience for visitors. Whether enjoying the custom baths by the river or the grand Sennin Bath in winter, the town provides an immersive and tranquil environment for relaxation. The experience at Kawayu Onsen is not just about the hot springs, but about connecting with nature in a uniquely Japanese way, offering a sense of peace and rejuvenation that is hard to find elsewhere. It’s a must-visit destination for those seeking both relaxation and a deep connection to nature.
