韮山温泉土地第三号泉
Nirayama Onsen Tochi Spring No. 3A simple thermal spring rising from Nirayama Onsen Tochi Spring No. 3. At 29.2 °C it is a cold-mineral source, heated for bathing, and its weakly alkaline chemistry (pH 8.7) gives the soft, slippery feel of Japan's beauty-water family. Lightly mineralized and very gentle, it is the kind of low-temperature water suited to long, unhurried soaks — fitting for Hatake Onsen, a designated national health resort spring.
