“The onsen village, Yudanaka, is known as the home of Japan’s famous ‘snow monkeys,’ a troop of some 200 Japanese macaques who live in and around the onsen baths. The monkeys and their mountain hot tub can be found at Jigokudani Yaen-koen. The park has been operating since 1964, so the monkeys can no longer be described as truly wild. Still, it’s a unique chance to see them up close.” –from Lonely Planet, Japan
