Nagano is a Japanese prefecture famous for its hot springs. And there is one thing special about it: It is known to be the only place in the world where monkeys bathe in hot springs. Slide the gallery to see some Japanese macaques who are feeling really comfortable! 

Jigokudani Yaen-koen was opened in 1964, at an altitude of 850 meters. It is located in the Valley of Yokoyu River, sourced from Shiga-Kogen of the Joshinetsu-Kogen National Park in northern Nagano Prefecture. The macaques have become quite famous on the internet for their bathing habit. Every winter, tourists visit the hot spring and take pictures of the macaques enjoying themselves. However, you cannot jump in the water and bathe with them - they apparently do not like to share!
