Jigokudani Monkey Park: Tickets, Access and Best Time to Visit
Aug 25, 2026
The monkeys do not perform. That is the first thing to understand about Jigokudani Monkey Park. They are wild Japanese macaques who live on the slopes above a river gorge in northern Nagano, they come down when they feel like it, and on a mild fall afternoon they may not come down at all.
When they do, in the deep cold of January and February, you get the picture everyone knows: a troop of red-faced macaques sitting shoulder-deep in a steaming pool while snow falls on their heads. Jigokudani Yaen-koen is the only place in the world where wild monkeys bathe in a hot spring, and it takes about half a day from Nagano and a full day from Tokyo.
Admission is going up. From December 1, 2026, the gate price rises from ¥800 to ¥1,000 for adults (18 and over) and from ¥400 to ¥500 for children from elementary through high school, as announced by the park's own site. Children under six stay free with an adult.
Buy online and you pay less. Web tickets from that date are ¥880 for adults and ¥440 for children, so booking ahead saves ¥120 a head and skips the window queue. The annual pass goes from ¥5,000 to ¥6,000.
Opening hours run 8:30 to 17:00 from April through October and 9:00 to 16:00 from November through March. The park has no regular closing days, though it shuts occasionally for weather. Cards and IC money are accepted at the gate; QR payments are not.
Plan on 45 minutes to an hour inside. There is one main pool, a viewing area around it, a stretch of river where the troop sits and grooms, and a small visitor center.
We'll build a costed, pre-planned Japan itinerary you can customise to your taste.
The park is in Yamanouchi, in the far north of Nagano Prefecture, at about 850 meters in the Yokoyu River valley inside Joshinetsu Kogen National Park. Snow covers the ground for roughly a third of the year.
The name means Hell Valley, from the steam venting out of the cliffs and the boiling water bubbling up through the rock. It is the same name used for the geothermal valley at Noboribetsu in Hokkaido, and the two are unrelated.
There is no way to drive to the gate. Every route ends with the same walk, and that walk is part of the trip.
The direct option is the Shiga Kogen express bus from the east exit. It runs to the Snow Monkey Park stop in about 45 minutes for ¥2,000 one way, according to Nagano's prefectural tourism board.
The alternative is the Nagano Dentetsu line to Yudanaka, the last station. The limited express takes 45 minutes and costs ¥1,590; the local takes 70 minutes and costs ¥1,190. Neither is covered by the Japan Rail Pass, although the shinkansen to Nagano is. From Yudanaka, a short local bus runs to Kanbayashi Onsen.
The Snow Monkey Pass bundles the transport and park admission into one ticket and is worth checking if you are doing the round trip in a day.
From either the bus stop or Kanbayashi Onsen it is about 1.6 km to the gate, which takes 30 to 40 minutes. The trail is a gravel forest path along the valley, level for most of its length with a climb at the end.
In winter it is packed snow and ice. Proper boots matter more here than anywhere else in a normal Japan trip, and cheap crampons are sold at the trailhead shops. There is no shelter on the path.
It works, but it is a long one. The Hokuriku Shinkansen reaches Nagano in about 90 minutes, and with the bus and the walk you are looking at roughly three hours each way. Leaving Tokyo by 8:00 gets you to the monkeys around midday with time to get back.
If you would rather not manage the connections, a bullet train day trip from Tokyo handles the transfers and the timing for you.
January and February are the answer. The pool is busiest when the air is coldest, the snow on the surrounding trees is at its heaviest, and the monkeys have the most reason to be in the water.
December and March still deliver snow and bathing, with noticeably fewer people. Visit in those months if the photograph matters less than the experience.
From April through November the troop still comes down, because park staff feed them at the pool year-round, but they mostly sit around it rather than in it. The park is honest about this: monkey appearances are most erratic in fall, when food in the forest is plentiful and they have less reason to come.
The park posts a daily monkey forecast and a live camera on its website. Check both the morning you go. Typical arrival is between 9:00 and 10:00, with the troop heading back up the mountain by late afternoon.
Japanese macaques live farther north than any primate other than humans, surviving winters that regularly drop well below freezing. Thick winter coats do most of the work. The hot spring is a local invention.
The story starts at Korakukan, a hot spring inn that has stood in the valley since 1864. In 1963 a young female macaque climbed into its outdoor bath, apparently after apples thrown into the water. Others copied her. The park opened the following year, in 1964, partly to give the monkeys a pool of their own so they would stop using the human one.
It is learned behavior passed down through the troop, not instinct, and it is confined to this group. A 2018 study published in the journal Primates measured stress hormones in the park's females and found that bathing lowered them, so the soak does more than keep them warm.
The troop numbers roughly 160 animals across several matrilines, and the hierarchy is visible if you watch for ten minutes: who sits in the warmest spot, who grooms whom, which mothers hold the center of the pool.
The viewing area is small and the crowd concentrates at one edge of the pool. In peak season you will be standing shoulder to shoulder for the classic shot.
Walk 50 meters past it and the crowd disappears. The monkeys spread along the river and up the cliffs, and this is where you actually watch them behave rather than photograph them: infants wrestling, adults picking through fur, young males testing the rock walls.
The rules are short and enforced. Stay on the path, do not feed them, do not touch them, and do not use flash. Do not crouch down to a monkey's eye level or hold eye contact, which reads as a challenge. Keep bags closed, because they will investigate food. Mothers with infants get the widest berth.
These are wild animals habituated to people, not tame ones. Nobody gets hurt if visitors behave, and the park has run this way since 1964.
Winter here is not Tokyo winter. The valley sits at 850 meters, the walk is exposed, and the last section is often sheet ice under fresh snow.
Waterproof boots with real grip, not sneakers. Slip-on crampons cost a few hundred yen at the shops by the trailhead and are worth buying
Waterproof trousers or at least something you do not mind sitting on wet rock in
Gloves you can shoot in, because bare hands stop working fast at the pool
Cash, even though the gate takes cards, since the small shops on the trail may not
No umbrella. You need both hands on the icy sections
For cameras, the pool sits in a shaded gorge and the light is flat and dim, especially before 10:00 and after 15:00. A lens that works at wide aperture helps more than a long zoom does; the monkeys come within a few meters and a 35mm to 85mm range covers almost everything. Steam fogs lenses on the way in, so let the gear cool outside before you uncap it.
Leave the drone at home. They are banned, as is anything that makes sudden noise near the troop.
Staying overnight nearby is the single best upgrade to this trip. It gets you to the gate at opening, before the tour buses from Nagano arrive around 11:00, and it turns a rushed day into an easy one.
Shibu Onsen is the obvious base: nine bathhouses, wooden inns on a lane barely wide enough for a car, and the trailhead ten minutes away on foot. Guests get a key to all nine baths and a stamp book to work through them.
Korakukan, the inn where the whole bathing habit started, sits inside the park itself and still takes overnight guests. It is basic and remote, and the monkeys wander past the windows.
Yudanaka has more rooms at lower prices and sits next to the station, which suits anyone arriving late or leaving early. Kanbayashi Onsen, the closest cluster to the trail, is quieter and smaller than both.
Book winter weekends and the New Year period well ahead. The valley has a limited number of rooms and the monkey season is short.
Most people pair the park with something else in the valley rather than going straight back.
Shibu Onsen is a ten-minute walk from the trailhead: a narrow street of wooden inns with nine public bathhouses that guests visit in sequence, clogs on, towel in hand. It is the most atmospheric place to stay if you want an early start at the park.
Yudanaka Onsen is bigger, cheaper and right by the station, with day-use baths near the platform if you only want a soak before the train back.
Zenko-ji Temple in Nagano city dates to the 7th century and holds what is said to be the first Buddhist image brought to Japan, hidden from view. The dark passage beneath the main hall, where you feel along the wall for a key in total blackness, is the part people remember.
Soba is Nagano's dish, and the prefecture grows the buckwheat for it. Togakushi soba near Nagano city is the version worth going out of your way for, served in small coiled bundles on a woven tray.
Skiing is 30 minutes further up the same road, at Shiga Kogen, the largest ski area in Japan. There are also ski resorts near Tokyo if you want snow without committing to Nagano, and our guide to snow monkeys and alpine Nagano covers combining the two.
Matsumoto Castle is about an hour south by train, and its black keep is one of only twelve original castle towers left in Japan.
A Nagano and Hokkaido snow route strings the monkey park together with the skiing, if you want the whole winter north in one trip.
In winter, yes, with one condition: go because you want to watch wild animals for an hour, not because you want a specific photograph. People who come only for the shot are the ones who leave disappointed when the troop stays high on the mountain.
Outside winter it is a pleasant forest walk to see monkeys sitting near a pool, which is a different and smaller experience. If your trip lands in July, spend the day at Kamikochi or Matsumoto instead and save this one for a cold-season visit.
If you do go in January or February, allow more time than the timetables suggest, wear boots you can trust on ice, and give yourself permission to put the camera away once you have the shot.
For comparison, Kyoto has its own troop at Arashiyama's monkey park, where the macaques are the same species with a hilltop view over the city instead of a hot spring. It is far easier to reach and a different kind of visit.
