The “snow monkey” is known overseas as a emblematic feature of Japan. More specifically, the term refers to “Japanese monkeys soaking in hot springs.” The Jigokudani Onsenkyo, a hot-spring village located in a valley near the Shiga Kogen Highlands in northern Nagano Prefecture, is famous for its snow monkeys. The “Jigoku Dani Yaen-koen” in the hot spring resort is a park where wild Japanese monkeys can be observed. In the winter, they can be seen soaking in the hot springs, earning the park the nickname “Snow Monkey Park” both in Japan and abroad.
