Snow monkey in Yudanaka, Nagano. The Snow Monkeys hang out in a hot spring (温泉) to fend off the cold. Because so many people come to this place, the monkeys are generally accustomed to the presence of humans (wielding cameras) and let you get very close. However, they are wild animals and they can come and go as they please. There are no fences or cages to keep them in the area. Only the warmth of the hot spring keeps them here.
