Jigokudani Snow Monkey Park is Japan's most internationally famous wildlife photography location, where wild Japanese macaques can be watched at close range in a mountain ravine and, in winter, often photographed bathing in hot springs. It is strongest for photographers and general wildlife travelers who want a highly distinctive single-species experience with extraordinary visual payoff rather than broad biodiversity.
