A blended source that brings together the Yufu-no-yu and Asagiri-no-yu wells, classified as a simple thermal spring — neutral, hypotonic and light on the body at 832 mg/kg of dissolved solids. At 71.6 °C it ranks among Japan's hottest natural sources, and the posted panel records it reaching the bathing position at 43.8–50.4 °C. What lifts it above ordinary simple water is metasilicic acid at 226 mg/kg, enough to leave the thin silica film that places this spring in Japan's beauty-water family. The panel documents the water for neuralgia, joint stiffness, bruises and sprains, convalescence and fatigue recovery.

A big concrete hotel with dinner and breakfast as a buffet. Brief notes on the food — wagyu, crab, tuna, tempura, and lord have mercy, a cotton candy machine. Also lots of local alcohol and an amazing view from the room — no regrets! The hotel has several baths. Photos from Google — it was crowded. Water temperature is comfortable, composition sign photo attached. There are both indoor and outdoor baths. The "barrel" baths had herb sachets in them — cool water, great for soaking after the hot baths. One bath block is a floor up, and where the barrel photo is from — there's now an additional fence, which is a shame. On the lower floor in the garden there's a stone bath with a view of the mountain, and in spring it's all cherry blossoms. Also a sauna and an ice-cold bath. Higaeri is available.
