Seeing the monkeys close, in total freedom, perhaps while they are enjoying the warm thermal waters of a Japanese onsen…. Is the reality of the Jigokudani park, also known as Snow Monkey Park, in Japan, precisely in the Nagano prefecture.
Totally one of the experiences to not to miss in Japan, I recommend visiting the Snow Monkey Park overnight in the Yamanouchi area, in Yudanaka or Shibu Onsen.
Jigokudani is a mountainous area in the Japanese Alps, and in its forest which is part of the Shigakogen Natural Park there are many Japanese macaques that often find themselves in the Yokoyu River area and immerse themselves in the natural onsen found in this hot spring area.
But not only the monkeys can enjoy the warm thermal waters of this area: the nearby towns of Yudanaka Onsen and Shibu Onsen allow you to stay in ryokans and immerse yourself in the warm thermal waters of Nagano prefecture.
