Jigokudani Park - The monkey onsen

The Jigokudani park is a famous hot spring area near Nagano. The name Jigokudani (地獄谷 lit.: "Hell Valley") is due to the steam and boiling water bubbling up from the frozen ground. It is famous for its large population of wild snow monkeys that come to the valley during winter when the snow covers the park. The monkeys descend from the steep cliffs and the forest to sit in the warm hot springs and return to the safety of the forests at night.

The monkeys of Jigokudani Park

Although the park is open year-round, the monkeys are particularly photogenic when the area is covered in snow. Generally, there is snow from December to March, and the best time to visit is between January and February. The monkeys usually enter the bath, but they need some encouragement from the park staff throwing food into the pool. Accustomed to humans, the monkeys can be observed up close and usually ignore their human guests. It is prohibited to touch or feed the monkeys. Visitors will likely encounter monkeys along the way to the pool. The monkeys live in large social groups, and it can be quite fun to observe their interactions.
