The world's only site where wild Japanese macaques bathe in a natural hot spring. Most spectacular December–February in deep snow. A 1.6km forest trail leads to the park.
Jigokudani Yaen-koen, known internationally as the Snow Monkey Park, protects the only place in the world where wild Japanese macaques regularly bathe in a natural hot spring. The park sits in a steep, forested gorge near Yamanouchi, reached by a roughly 1.6-kilometer walking trail from the car park through cedar and beech forest, gaining modest elevation along a well-maintained but sometimes icy path. At the park's central pool, troops of macaques descend from the surrounding cliffs to soak in the steaming rotenburo, grooming each other and playing at the water's edge just a few meters from the raised viewing path, while rangers maintain a boundary to keep visitors and monkeys at a safe distance. The spectacle is at its most striking from December through February, when snow blankets the gorge and steam rises off the water around the monkeys' fur-covered faces, producing the park's iconic images; monkeys are present year-round, but they spend far less time in the water outside the coldest months, sometimes just passing through instead of bathing. A visit including the walk in, viewing time, and walk out takes about 1.5 to 2 hours, with an extra 20 to 30 minutes for those who continue to the nearby onsen town of Shibu or Yudanaka for lunch. Winter weekends and Japanese public holidays bring the heaviest crowds around the pool, so arriving at opening time or in the early afternoon lull between tour groups improves the odds of open sightlines to the water. Summer visits show more monkeys foraging in the forest and fewer at the pool itself.

When to visit
Weekday mornings in December through February bring the most monkeys into the pool and the fewest crowds along the viewing path.
