Nagano to Snow Monkey Park Bus: The Complete 2026 Guide (With Summer Schedules)

TL;DR: Take the Nagano Dentetsu express bus from Nagano Station East Exit to Yudanaka (40-50 min, ¥1,500), then transfer to the local bus to Kanbayashi Onsen (10 min, ¥310) and walk 30 min to the park.

The first time I tried to get from Nagano Station to the Jigokudani Snow Monkey Park, I stood in front of the ticket machines at the bus terminal for a solid five minutes trying to figure out which route actually went where. Express bus or local? Do I buy both tickets now or pay on board? And — this one tripped me up — does the bus actually drop me at the trailhead, or am I walking from somewhere else entirely?

Here's what I learned after three trips, two seasons, and one very long walk in the wrong direction.

What's the fastest route from Nagano Station to the Snow Monkey Park by bus?

The express bus from Nagano Station East Exit to Yudanaka Onsen (40-50 minutes, ¥1,500 one-way) is your fastest bet, but here's the catch — it only runs December through March. From Yudanaka, you hop on the local bus to Kanbayashi Onsen (10 minutes, ¥310), then hike the 1.6 km trail to the park entrance in around 30 minutes. Total door-to-trailhead time: 80-90 minutes if your connections line up.

I've taken this route twice in January and once in early March. The express bus leaves from Platform 4 outside the Nagano Station East Exit — look for the sign that says "Snow Monkey Park" in English and the Nagaden (長電) logo. During ski season, buses run every 60-90 minutes or so, starting around 8:30 AM, with the last departure usually around 3:00 PM.

The express makes 2-3 stops between Nagano and Yudanaka (including one at Suzaka), but most tourists board at Nagano and ride the whole way. You'll pull into Yudanaka Station, walk across the small plaza, and grab the Kanbayashi-bound local bus from the stop right in front of the station building.

How do I get to the Snow Monkey Park from Nagano in summer (April-November)?

The express bus doesn't run outside ski season, so from April through November you've got two options: take the Nagano Dentetsu train to Yudanaka (45 min, ¥1,290) or the longer local bus via Shinshu-Nakano, then connect to the Kanbayashi-bound bus. The train's your move here — it's more frequent and way less confusing. I've used it twice in May and once in early November.

From Nagano Station, head down to the underground Nagano Dentetsu platform (follow signs for 長野電鉄 / Nagaden). The limited express "Snow Monkey" train rolls out roughly once an hour and takes 45 minutes to Yudanaka; the local train takes 50-55 minutes and costs a touch less (¥1,190). Both drop you at the same place.

Once you reach Yudanaka Station, the local bus to Kanbayashi Onsen runs year-round but less frequently in summer — usually every 60-90 minutes, with the last bus around 4:30-5:00 PM. Check the timetable posted outside the station or ask the information desk inside. Same ¥310 fare, cash only, and the driver usually calls out "Kanbayashi Onsen" when you're getting close — so you won't accidentally stay on too long.

Alternative summer route via Shinshu-Nakano

There's a local bus that runs from Nagano Station to Shinshu-Nakano Station, then connects to another local route toward Kanbayashi. I tried this once in October because I missed the train by three minutes and didn't want to hang around for an hour. Total time came to about 90 minutes, and the connections felt way tighter than I'd like. Unless the train schedule really doesn't work for you, stick with the train + local bus combo.

Where do I buy tickets for the Nagano to Snow Monkey Park bus?

Buy your express bus ticket (Dec-Mar) at the Nagano Dentetsu ticket counter inside Nagano Station, near the Zenkoji Exit side of the main hall — not from the driver. The counter's open 7:00 AM to 7:00 PM and takes credit cards. The local bus from Yudanaka to Kanbayashi Onsen? That's cash-only — pay when you board or get off (there's a fare box next to the driver).

For the train option (year-round), grab your ticket from the Nagano Dentetsu machines on the underground platform or at the staffed counter. The limited express needs a separate ¥100 surcharge on top of the base fare, but the machine will walk you through it. I missed this on my first go and had to backtrack — the conductor checked tickets and made me pay the difference on board, which was awkward.

JR Pass holders: sorry, but the JR Pass doesn't cover the Nagano Dentetsu train or any of the buses to Yudanaka or Kanbayashi. You're paying out of pocket for this whole leg.

What's the transfer point at Kanbayashi Onsen like?

Kanbayashi Onsen is basically a small bus stop with a covered shelter, a public restroom, and a parking lot — that's your whole setup. The trailhead to Jigokudani's marked with a big wooden sign in English and Japanese, and the path starts across the small bridge behind the parking area. In winter, it's packed snow and ice; in summer, you're looking at gravel and forest trail with a few wooden boardwalk sections thrown in.

When I first got to Kanbayashi in January 2024, maybe eight people were getting off the bus. By the time I walked back to catch the return bus at 4:45 PM, the shelter was packed with 20+ tourists all trying to figure out which bus goes where (there are two routes that stop here — and honestly, watching people board the wrong one is its own form of entertainment). The bus back to Yudanaka says "湯田中駅" (Yudanaka Station) on the front panel. Don't get on the one that says "志賀高原" (Shiga Kogen) unless you're headed up the mountain.

How long is the walk from Kanbayashi Onsen to the park entrance?

It's 1.6 km and takes 25-35 minutes depending on your pace and the trail conditions. Winter? Wear boots with real grip — the packed snow gets icy, especially in the morning shade. In summer, the trail's mostly flat and straightforward, but it can get muddy after rain. A few wooden staircases and a couple of short uphill sections, but nothing that'll break you.

You'll cross two small bridges, pass a few traditional wooden buildings (one's a small shrine), and follow the river upstream. Park entrance gate's at the end — you'll spot the ticket booth and the big English sign. Entry is ¥800 for adults, ¥400 for kids (as of 2026).

What time should I plan to leave the park to catch the last bus back?

The last local bus from Kanbayashi Onsen back to Yudanaka typically leaves between 5:30-6:00 PM in winter and 5:00-5:30 PM in summer, but it changes by season — check the exact time when you arrive. Miss it and you're looking at a 40+ minute walk along Route 志賀高原 to Yudanaka in the dark, which trust me, is not an experience you want in January.

I learned this the hard way in February 2025. I got so caught up trying to photograph the monkeys in the afternoon light that I completely zoned out on the time. By the time I walked back to Kanbayashi, the last bus had already left at 5:30 PM — I'd missed it by eight minutes. A taxi driver in the parking lot threw me a lifeline and took me to Yudanaka for ¥2,000.

My rule now: if I want to catch that last bus, I'm leaving the park entrance by 4:45 PM at the latest. That gives me 30 minutes to walk back to Kanbayashi, plus a 10-minute buffer in case the trail's icy or there's a crowd.

What are the most common mistakes tourists make on this route?

Not confirming the return bus time is the biggest culprit — but there are three others I see constantly.

1. Assuming the express bus runs year-round. It doesn't. The Nagano to Yudanaka express bus only operates December-March. If you're showing up in May, July, or October, you're taking the train or the longer local bus route. I've watched tourists argue with the information desk staff about this one — the bus simply doesn't exist outside ski season.
2. Not bringing cash for the local bus. The Yudanaka-Kanbayashi bus is cash-only. The driver won't take credit cards, IC cards, or foreign currency. If you don't have ¥310 (or a ¥500 coin for change), you can't board. There's an ATM at Yudanaka Station, but it's inside the building and you might not have time between connections.
3. Wearing the wrong shoes for the trail. In winter, the Kanbayashi-to-park trail is packed snow and ice. Sneakers or flat-soled boots will slide right out from under you. I saw two people fall on the same icy patch near the second bridge in January 2024. Summer's easier but still uneven — skip the sandals and heels.
4. Not checking whether Route 292 is open. This one's for drivers. Route 292 (Shiga-Kusatsu-Kogen Road) shuts down every winter (mid-November to late April) and it's the only direct car route between Kusatsu Onsen and Shiga Kogen. Planning a car trip that hits both the Snow Monkey Park and Kusatsu? Check the closure dates first. I didn't, and ended up rerouting through Nagano city on my November 2023 trip.

When is the bus most crowded?

The 10:00-11:00 AM express bus from Nagano to Yudanaka and the return buses between 3:00-5:00 PM get the worst crowds, especially on weekends and Japanese holidays in January-February. If the bus fills up, you're waiting for the next departure (60-90 minutes). I've seen this happen twice — once on a Saturday in late January when a large Chinese tour group loaded on, and once on a Monday that happened to be Coming of Age Day (成人の日).

Want a seat during peak season? Aim for the 8:30 AM or 9:00 AM departure from Nagano. The early buses are hardly ever packed, and you'll hit the park before the midday crush (which means 30-50 people on the viewing platform instead of 80-100).

How much does the entire trip cost from Nagano Station to the Snow Monkey Park?

Total one-way cost: ¥2,610 in winter (express bus + local bus + park entry) or ¥2,400 in summer (train + local bus + park entry). Here's what you're actually paying for:

For a round trip, double those numbers. Nagano Station and back runs you roughly ¥5,220 (winter) or ¥4,800 (summer). That doesn't include lunch, drinks, or stops in Yudanaka or Shibu Onsen along the way.

Is taking a taxi from Nagano Station to the Snow Monkey Park worth it?

A taxi from Nagano Station to Kanbayashi Onsen costs ¥8,000-10,000 one-way and takes about 45 minutes — only really worth it if you're splitting with 3-4 people or dealing with mobility issues. The taxi drops you right at the trailhead, which skips the bus transfers and timing stress, but you're still walking 30 minutes to get into the park.

I priced this out with a driver at Nagano Station in March 2024. For two people, it's ¥10,000 round-trip plus waiting time (most drivers charge ¥3,000-4,000/hour if you want them to wait while you visit the park). That puts you at ¥13,000-14,000 for two people versus ¥10,440 for two people on the bus/train. Time-wise, you're maybe saving 15-20 minutes. Unless you're traveling with a big group or you've got luggage and mobility constraints, I'd stick with the bus.

Frequently Asked Questions

Is there a direct bus from Nagano Station to the Snow Monkey Park?

No. Every route needs at least one transfer — either at Yudanaka Station (winter express bus or year-round train) or Kanbayashi Onsen. Closest you can get by bus is Kanbayashi Onsen, which is a 30-minute walk from the park entrance.

Does the JR Pass cover the Nagano to Snow Monkey Park bus or train?

No. The JR Pass covers the shinkansen from Tokyo to Nagano, but it doesn't cover the Nagano Dentetsu train, the express bus, or the local bus to Kanbayashi Onsen. You're paying separately for the entire Nagano-Yudanaka-Kanbayashi leg.

Does the trail from Kanbayashi to the park close in winter?

No. The trail stays open year-round, but in winter (Dec-Mar) it's covered in packed snow and ice. The park maintains the path and puts up handrails on steep sections, but you'll need proper winter boots. I've walked it in January and February without problems, but I saw two people slip near the bridges both times.

Can I stop in Yudanaka or Shibu Onsen on the way to the park?

Absolutely. Take the express bus or train to Yudanaka, walk to Shibu Onsen in about 10 minutes, or explore Yudanaka's main street before catching the local bus to Kanbayashi. Most people do this on the return trip — hit the park in the morning, come back to Yudanaka in the afternoon, and spend an hour or two in Shibu Onsen before heading back to Nagano.

What's the last entry time for the Snow Monkey Park?

The park officially closes at 5:00 PM (last entry 4:30 PM), but the monkeys often bail on the bath area by 4:00-4:30 PM, especially in winter when darkness comes early. Want to see them actually soaking in the hot spring? Get there before 2:00 PM.

The Nagano to Snow Monkey Park bus route isn't complicated once you've done it — but the first time, the transfers and timing can feel overwhelming. My biggest piece of advice: build in buffer time, especially for the return leg. Miss that last bus back to Yudanaka and you're either dropping ¥2,000 on a taxi or walking 40 minutes in the dark, neither of which is appealing after you've been standing on an icy viewing platform for two hours watching macaques bathe.

If you're staying overnight in Yudanaka or Shibu Onsen, the whole timing pressure vanishes — you can visit the park in the morning, take your time, and walk back to your ryokan in the late afternoon without stressing about that last bus. That's how I prefer to do it these days.
