Yudanaka Onsen Snow Monkey

Yudanaka Onsen is the gateway hot spring resort for Jigokudani Monkey Park in Yamanouchi, Nagano Prefecture, the world-famous site where wild Japanese macaques descend from snowbound forests to soak in natural sulphurous thermal pools alongside human bathers. The thermal waters at Yudanaka carry hydrogen sulfide and sulfurous compounds prized in Japanese therapeutic tradition for skin purification, muscle relaxation, and the deep warmth that penetrates the cold mountain air of Nagano's snowy winters. Staying at Yudanaka offers the rare experience of sharing a geothermally active landscape with Japan's indigenous snow monkeys, blending wildlife encounter, mountain onsen culture, and winter scenery into an unforgettable single destination.
