Kawayu Onsen is a very unique hot spring with a rare feature. It's located in an environment where, as the saying goes, "if you dig into the riverbed, hot water springs forth." The hot spring that constantly springs forth from the riverbed has a source temperature of over 70 degrees Celsius, making it very hot. When this hot water mixes with the water from the Odo River, a tributary of the Kumano River, it forms a moderate hot spring. The hot spring that springs forth from the riverbed is said to have a rich amount of hot spring components dissolved from the deep underground bedrock, making it abundant in hot water and easy for the body to absorb its components. Since the hot spring water springs forth naturally, there is no need for additives or heating, and it can be enjoyed in its natural state. The hot spring that springs forth from the riverbed is called "Kawayu Onsen" due to its unique characteristics, and it's loved by locals and tourists alike. Kawayu Onsen, where you can enjoy the hot spring while touching the blessings of nature, is treasured as a local treasure!
