Surviving the Freeze: A Winter Guide to Japan’s Famous Snow Monkeys

Before the gentle winter sun brushes the snow with light, a troop of snow monkeys huddles together, dreaming in the silent, icy forest. As dawn stretches across the sky, they make their way down the mountains toward the steaming volcanic hot springs…

The Arrival & The Refuge

Out of breath and chilled to the bone, we caught our first glimpse of Korakukan’s faint lights—our secluded traditional ryokan nestled deep in the valley. After 30 minutes of trudging through ankle-deep snow, the narrow cliffside path was barely visible under torchlight, but the glowing paper lanterns signalled we had finally arrived.

Inside, our host ushered us into a traditional tatami room, where a steaming pot of tea sat atop a warm kotatsu table. With our legs tucked beneath the heated blanket and thick wool futons laid out on the floor, the rustic timber inn felt like the ultimate winter sanctuary.

Morning with the Monkeys

After breakfast, we navigated the icy steps down to the riverbank. Just 100 metres from our door, Korakukan is the only accommodation inside the park, so we could reach the hot springs long before the daytime crowds arrived.

Snowflakes drifted through the air and monkey footprints crisscrossed the untouched snow, which glistened like a fresh layer of powdered sugar.

Steam curled around the monkeys as they lounged in the thermal water, their bright red faces glowing and wet fur plastered to their heads, ears poking out like tiny flags. Some surrendered to drowsiness, eyes fluttering shut, while others delicately groomed one another with remarkably human hands.

Mother macaques cradled fluffy babies whose eyes shone like melted toffee, while mischievous youngsters somersaulted through the powder and shaped miniature snowballs with nimble fingers.

As Kayo Miyati, a park staff member, shared with us: “Togura is the 21-year-old alpha male who leads the troop… I love animals and am happy to work in this environment. I work here and I feel healed.”

Valley Hierarchy

In the valley, a rigid social order shapes every day. Only high-ranking monkey families are permitted in the blissful warmth of the hot springs. Meanwhile, lower-ranking monkeys shiver at the edges, forced to find heat wherever they can.

We watched the less fortunate monkeys, their fur sodden and clumped with melting snow, huddling tightly together along the warm water pipes that thread through the snow.

Evening, Hot Pot & Farewell

As late afternoon approached, we slipped into Korakukan’s open-air outdoor bath, watching the faint outlines of monkeys playing on the snowy roof above. Afterwards, we sat at a low table for a sizzling feast of nabemono—fresh vegetables, tempura and zaru soba cooked over a table-side burner—paired with cold local Japanese beers.

…As the sun slipped away, winter draped the valley in deepening shadows. The snow monkeys slipped quietly into the frosted forest, huddling close to share their warmth through the long, cold night.

The Practical Guide: Planning Your Visit

🏨 Why Stay at Korakukan vs. Yudanaka Town

Option	Pros	Cons
Korakukan Ryokan (Inside Park) ♨️	• Beat all day-trippers to the park • Authentic, rustic ryokan experience • Onsen with monkeys on the roof!	• Requires walking in with luggage • Basic amenities (shared facilities)
Yudanaka / Shibu Onsen (In Town) 🏯	• Convenient transport connections • Diverse dining & luxury ryokan choices • Luggage storage readily available	• Must take a bus/taxi to trailhead • Arrive alongside peak day-trip crowds

🐒 Train to Trailhead: Step-by-Step Transport

1. 🚄 Tokyo to Nagano Station: Board the JR Hokuriku Shinkansen from Tokyo Station to Nagano Station (approx. 80–90 mins, covered by JR Pass).
2. 🚃 Nagano to Yudanaka Station: Transfer to the Nagano Dentetsu (Nagaden) Line express train (approx. 45 mins).
3. 🚌 Yudanaka to Kanbayashi Onsen: Catch the local Nagaden Bus to the Kanbayashi Onsen bus stop (approx. 15 mins).
4. 🥾 The Final Hike: Walk 1.8 km (approx. 30–40 mins) along the picturesque, snowy forest trail directly to Jigokudani Monkey Park.

💳 Payment Tip

Park entry accepts credit cards, IC cards (like Suica or PASMO) and cash. However, it is always wise to carry a little spare cash in Japanese Yen in case local buses, coin lockers, or small vendors along the trail experience terminal outages or only accept cash.

🚐❄️ Getting from Yudanaka Station to the Trailhead: Most local ryokan hosts offer a free pick-up service for overnight guests at Yudanaka Station. If you are heading straight to the park, a local bus or taxi takes around 10 minutes to reach the trailhead (or a 30-minute uphill walk if you prefer the exercise). Keep in mind that no vehicles can access the actual park—everyone must walk the final stretch along the snowy forest path!

💡 Navigating Japanese Trains: At first, the Japanese rail system can look daunting, but stations and platforms are clearly signed in English. If in doubt, the station staff are extremely helpful. Japanese trains are famously punctual, often leaving precisely on the second—so be on the platform ready to board a few minutes early. Regional connections run less frequently, so missing a train means enjoying a warm coffee at the station while you wait for the next service!
