The quality and quantity of the boiling hot spring water, that has continued to gush out of the earth from long ago, shows no signs of waning at all. The near boiling 98˚C water of Arayu (荒湯), the hot spring loved by locals, to this day continues to flow. Due to naturally occurring baking soda in the water, hot spring water is often also used in cooking. When you boil bamboo shoots and other mountain vegetables in the water, the color of the vegetables becomes bright and vivid. Tofu also melts and gains a mild flavor. The hot spring that can heal both the mind and body of visitors, as well as bring out rich flavors definitely has the mysterious ability to attract visitors.history and culture of hot springs
