Jigokudani Snow Monkey Park: Visiting Nagano's Bathing Macaques

Published October 13, 2026 at 10:35 PM JST | By Tokyo Paul

Among Japan's most delightful sights is a troop of wild monkeys relaxing in a steaming hot spring while snow falls around them. This scene happens at Jigokudani Monkey Park, a small valley in Yamanouchi, Nagano Prefecture, within Joshinetsu Kogen National Park. The park is known around the world as the home of the so-called snow monkeys, which are Japanese macaques that have learned to enjoy the warmth of the onsen (hot spring) during cold weather. Seeing them up close, in their natural mountain setting, is a memorable experience for travelers of all ages.

This guide explains what makes the park special, how to reach it, what the walk is like, and the best seasons to go. It also covers simple rules that keep both visitors and monkeys comfortable. With a bit of planning, you can turn the visit into a calm and wonderful day in the Nagano mountains.

Who Are the Snow Monkeys?

The animals here are Japanese macaques, known in Japan as nihonzaru. According to the Wikipedia article on the Japanese macaque, they live farther north and in colder climates than any other non-human primate, which explains the snow monkey nickname. Their thick brownish-grey winter coat thickens as temperatures fall, and they can cope with temperatures as low as minus 20 degrees Celsius. They are omnivores that eat a wide range of plants, along with insects and other foods, and their diet changes with the season.

Macaque society is fascinating to watch. Troops are built around families of females, who stay in their birth group for life, while young males eventually leave. Rank is inherited from the mother, and the social structure affects who gets the best spots, including the best place in the warm water. Researchers have noted that higher-ranking females tend to claim the limited space in the bath, and that winter bathing is linked with lower stress. Watching the interactions, such as grooming and gentle play, can feel like observing a small village.

The habit of visiting the hot spring is a more recent story than many people expect. The same source notes that the monkeys' presence at the springs dates to the 1960s, when they were encouraged to gather there. The park staff continue a regulated feeding routine, which helps the monkeys stay close to the valley, and this is why visitors can often see them even though they are wild animals.

When to Go

The monkeys bathe mainly in winter to stay warm, so winter is the classic season for the famous hot spring photos. According to the park's official site, snow covers the ground for around a third of the year, and the scene of macaques in a steaming pool with a white backdrop is the image most people have in mind. If you are traveling in this season, dress warmly, wear boots with a good grip and be prepared for cold air. The park notes that in winter, entry priority may be given to visitors who have purchased tickets online, so it is wise to check the official page before your trip.

Other seasons are lovely too, but the experience is different. The park explains that bathing happens mainly in winter, that sightings are not guaranteed, and that they are especially variable in autumn. In warmer months, the monkeys gather in the valley less often and forage elsewhere in the national park. Visitors who come in spring, summer or autumn can still enjoy the forest walk and the chance to watch monkeys going about their day. Opening hours differ by season, so check the park's official website for the latest schedule before you go. As a rule of thumb, aim to arrive in good time so you are not rushing on the trail, especially in winter when daylight hours are shorter.

Getting There and the Walk In

Jigokudani is about three and a half hours from Tokyo, and the usual route goes through Nagano city. From Nagano Station, the park's official access page describes taking the Nagano Dentetsu limited express, which takes about 38 minutes, to Yudanaka Station, then a bus of around 15 minutes toward the park. An alternative is an express bus toward Shiga Kogen from Nagano Station. Either way, you finish with a walk on a forest path.

That path is part of the charm. The trail runs for about two kilometers from the Kanbayashi Onsen area, along what the park calls the Yumichi Natural Trail, and it takes about 30 minutes on foot. The route is mostly flat with a few hilly stretches, and parts are unpaved, with stairs and uneven surfaces. Wheelchairs and carts cannot use the path, so travelers with mobility needs should read the official guidance carefully.

In winter the trail can be icy or snowy, so sturdy waterproof shoes with traction are very helpful. In other seasons, comfortable walking shoes are fine, and a light rain jacket is a good idea. Carry water and anything else you need, and keep your bag closed around the monkeys.

Etiquette and Visitor Rules

Respect for the animals comes first. The park is clear that humans cannot bathe in the monkeys' pool, and bathing with monkeys is strictly prohibited. Visitors enjoy the show from the viewing area, which keeps people and monkeys safe. The park also does not allow pets, including guide dogs, since dogs are natural enemies of monkeys. Guardians are asked to hold small children's hands, because the animals are wild and visitors share the space with them.

Simple common sense helps. Keep a respectful distance, avoid staring directly into a monkey's eyes, and never try to touch or feed them. Food in an open bag may attract attention, so keep snacks hidden. Move slowly, speak softly and let the monkeys decide how close to come. You can take plenty of photographs without bothering anyone, and a zoom lens makes it easier to capture close-up expressions from a polite distance.

If you want to soak yourself, the area has human-friendly hot spring towns nearby. Many visitors choose to stay overnight in the Yudanaka area, which makes the morning visit easier and gives you a chance to relax in an onsen of your own. Check local lodging options in advance, particularly in winter, when rooms can fill up.

Quick Takeaways

Jigokudani Monkey Park is a small, scenic valley where wild Japanese macaques bathe in hot springs, especially in winter. Reach it from Nagano Station by train and bus, then enjoy a forest walk of about two kilometers and roughly 30 minutes. Dress for the weather, check seasonal opening hours and ticket notes on the official site, keep a respectful distance, and remember that people cannot bathe in the monkeys' pool. Winter is the classic time for the hot spring scene, though other seasons have their own charm.

It is a joy to share a quiet mountain valley with these expressive animals. Bring patience, a warm coat and a little curiosity, and you will leave with a happy memory of Nagano's most famous residents. It is a quiet reminder of how wonderful time in nature can be.
