Jindaiji Natural Hot Spring Yumorinosato

A day-trip hot spring where you can soothe your mind and body with high-quality hot water. Because our natural running hot springs have the same chlorine and sodium salinity levels as the body, any burden on the hot springs is very low. No water is added, and our baths are filled from the source untouched. The reason behind the surprisingly jet-black color is due to an organic layer of what is known as “humic acid”, an aged combination of kombu and fern plants, that occupy the underground layers at a depth of 1500 meters. There are several types of baths that you can enjoy, from open air baths to water baths, rocks baths, and saunas. All of our baths are designed to Feng Shui principles.
