About Miyama no Yu
"Miyama no Yu" is a day-use hot spring facility located inside Michi-no-Eki Otari in Otari Village, Kitaazumi District, Nagano Prefecture. Its greatest pride is its luxurious 100% natural hot spring water, delivered straight from the source with no added water or heating, created by blending two springs of different temperatures, Kitakotani Onsen, long cherished as a hidden mountain hot spring, and Fubusou Gensen, and carefully managed to the perfect temperature through yumomi. The slightly cloudy sodium bicarbonate spring leaves the skin silky smooth and helps you stay warm long after bathing. The sauna is a very clean, hot dry sauna with no TV and soothing healing music playing. In addition, the superb cold plunge bath, generously fed with the area’s delicious mountain natural water straight from the tap, is of such high quality that it is drinkable, delivering an overwhelming cooldown.
