Ontake Myojin Onsen Yamayuriso sits in Kiso-machi at the foot of Mount Ontake, Nagano Prefecture. Sulfurous water rises at 44°C, feeding an indoor bath, an outdoor rotenburo bath and a sauna.
Insider tip — At the foot of sacred Mount Ontake, the volcano revered by Shugendo mountain ascetics and tragically remembered for the 2014 eruption that claimed 63 lives, Yamayuriso (mountain lily inn) channels the volcano's geothermal power into powerful sulfurous springs; visiting combines deep respect for the mountain's spiritual significance with the restorative power of its ancient thermal waters.
