If you ever find yourself in Nagano, Japan, consider checking out the Jigokudani Monkey Park in Yamanouchi. There you will find large groups of Snow Monkeys (Japanese Macaques) bathing in the park?s natural hot springs.
Established in 1964, the Jigokudani Monkey Park (altitude 850 meters) is located in the Valley of Yokoyu River. Because of the very steep cliffs and the steam coming off all of the natural hot springs, ancient people called this valley ?Jigokudani? or ?Hell valley?. The region is covered in snow almost one-third of the year.
