Yudanaka Onsen Guide: One Ryokan Night, Hot Springs and the Snow Monkeys

Yudanaka Onsen at a Glance: Is This Hot Spring Town Right for You?

Yudanaka Station is the last stop on the Nagano Electric Railway (Nagaden). The Yudanaka hot spring area spreads out from the station, so most inns are a short walk from Yudanaka train station or a quick pick-up away. Shibu Onsen sits just up the valley. Beyond it are Kanbayashi Onsen and the trailhead for the monkeys. Higher still are the slopes of Shiga Kogen.

Yudanaka fits best if two things are true. First, Nagano is already on your route (the city sits on the Hokuriku Shinkansen between Tokyo and Kanazawa). Second, an onsen night matters to you. If every night has to be in a big city, you can visit the monkeys as a long day trip from Nagano instead, though with much less spare time.

Yudanaka vs Shibu Onsen: Who Gets the Nine-Bath Key?

People mix these two up all the time. Shibu Onsen is known for its nine public bathhouses. Under the official nine-bath rules, guests staying at qualifying Shibu Onsen inns borrow a key from their accommodation and can use the baths from 6:00 to 22:00, subject to cleaning closures. Confirm eligibility with the Shibu inn. Day visitors may use No. 9, Oyu only, from 10:00 to 17:00: buy a ticket at the information centre or a designated inn, then ask a participating establishment to unlock it. The day-use price is ¥800 for adults and ¥500 for children.

Staying in Yudanaka does not automatically get you that key. Shibu is in the same valley but runs its own system.

If the nine-bath circuit is your main reason for coming, you'll need a Shibu inn that provides the key. If you're staying in Yudanaka, Shibu is still worth a walk before dinner. Its narrow lane has a more traditional atmosphere than the more modern Yudanaka. Just plan to do your soaking back at your own ryokan.

Public Baths, Foot Baths and Ryokan Hot Springs in Yudanaka

In practice, you have three ways to soak:

• Your ryokan's hot spring baths. On a one-night stay, most of your bathing happens here, in the evening and early morning.

• Kaede no Yu. This is a paid day-use bath beside Yudanaka Station, with a free footbath outside. The official town tourism guide lists ¥500 for junior-high age and above and ¥300 for elementary-school children, including bathing tax. The bath opens 10:00–21:00, last admission 20:30; it closes on the first Tuesday of each month, or the next day if that Tuesday is a holiday. It is useful after the monkeys if you have time before your train.

• Neighbourhood public baths. Yudanaka has its own small communal bathhouses, but they're run for locals and inn guests under local arrangements. Ask your inn's front desk before trying a door.

Some ryokan in the hot spring area also let day visitors use their indoor/outdoor baths in the afternoon. Ask locally. If you have tattoos, check the rules in advance. A private bath you can reserve is often the simplest solution.

The Heiwa Kannon and a Short Walk Before Dinner

Near the top of town, up a flight of steps, stands the Sekai Heiwa Kannon (World Peace Kannon). It's a 25-metre bronze statue built in 1964 in the grounds of Daihiden temple. It replaced an earlier statue that was taken by the military during the Second World War, and it overlooks the whole hot spring area.

You can combine it with Issa no Komichi, a hillside path named for the haiku poet Kobayashi Issa, who repeatedly visited Yudanaka's hot springs. The town's walking booklet links the Kannon area, Issa-do and Yumiya Shrine. Choose the walk before dinner if the weather and footing are suitable; hillside paths can be slippery in winter.

BIYUNOYADO: An Authentic Ryokan Night in Yudanaka

BIYUNOYADO (Issa no Komichi Biyu no Yado) is the Yudanaka inn on all three of our routes. You can walk from Yudanaka Station or request the inn's free station pickup. Tell the hotel your arrival time in advance, or call as you leave Nagano or arrive at Yudanaka. Its hot-spring page describes free-flowing natural onsen supplied by three spring sources.

Check In, Dinner and Bath Times

Aim to check in by mid-afternoon so you have time for a soak before dinner. The included dinner is a traditional Japanese-style meal served in a banquet hall rather than in your room, and you should confirm the arrival and dinner arrangements with the inn before travel. Ryokan dinners like this are usually multi-course Japanese cuisine, so arrive hungry.

The inn asks guests with food allergies, and anyone who wants vegetarian or vegan food, to tell it in advance. It says it will do what it can to accommodate food allergies, so give the details early.

Yukata robes are provided, and Wi-Fi is available in the rooms. Ask at check-in for the current bath cleaning and changeover times, and plan your main soaks for the evening and early morning.

Want somewhere to leave a day bag on the monkey morning? Ask at the front desk about luggage storage. On all three routes your large suitcase is sent ahead, so pack a small bag for every night until you meet it again. On GR505 and FG504, that means the two Kanazawa nights plus Yudanaka after leaving Kyoto. On GR510, the first delivery runs from Tokyo to Kanazawa around the Yudanaka stop. Do not rely on staffed baggage storage at Yudanaka Station: Nagaden's station information currently marks that service as suspended.

Rooms, Private Baths and the Fine Print

Our routes book a Japanese-style room. The inn offers Japanese-style rooms and rooms combining Japanese and Western elements. Japanese-style rooms usually have the classic layout: a tatami woven straw floor, a low table with seating cushions, and traditional futon bedding laid out at night. The official room descriptions list several sizes, including ten-tatami Japanese-style rooms for two to four guests. Confirm the room allocation for your party when booking.

Don't assume a private onsen comes with your room. The inn lists only three guest rooms with their own outdoor hot spring baths in the entire property, and those are specific room types. Separately, there is a rooftop private open-air bath for private use, booked in advance; the hotel's bath details list ¥2,000 for 40 minutes. Reserving that private onsen slot is not the same as having a private hot spring bath in your room.

The hotel's room descriptions list a bathroom and a private toilet, but these are separate from having a private hot-spring bath. Confirm the allocated room's facilities before booking. Confirm any additional services directly rather than treating them as included in the tour.

Getting to Yudanaka from Nagano Station and Nagano City

The rail approach on our three itineraries runs through Nagano Station. The Nagaden station there is underground, with its own entrance separate from the JR gates. For planning, allow at least 15 minutes to transfer from the Shinkansen, with extra time for luggage or buying a ticket.

A direct Nagaden limited express takes about 45 minutes to Yudanaka Station. Local trains take longer and may require a change at Shinshu-Nakano. The operator's fare table gives an adult base fare of ¥1,660 plus a ¥100 non-reserved limited-express supplement: ¥1,760 one way. Reserved seating costs extra. Use the current timetable to choose your train. On our routes, this limited-express leg is built into the itinerary.

Buy a paper ticket before boarding if travelling independently. Nagaden's ticket guidance distinguishes cashless payment at equipped ticket machines from boarding with Suica or PASMO: these cards do not yet work as direct train boarding cards. Direct IC boarding is planned for spring 2027; check the operator's announcement before relying on it.

If you have a morning in Nagano City, Zenko-ji Temple is the obvious stop. You can reach it by a local train to Zenkojishita followed by a walk, or a local bus from Nagano Station's Zenkoji Exit. Allow time for the temple and the walk back to your onward train. Nakamise Street, which leads up to Zenko-ji Temple, is a good place to buy souvenirs. Its shops and places to eat can easily fill an hour of your morning.

About rail passes: the Japan Rail Pass covers the Hokuriku Shinkansen to Nagano but not Nagaden, which is a private railway. On our routes the intercity trains are already ticketed, so adding a pass for those legs gains you nothing. Planning a route yourself? Add up the fares for the legs you'll actually take and compare that total with the pass price before buying.

A One-Night Yudanaka Onsen Itinerary

Use this as a flexible overnight plan; fit the Nagano sightseeing around the trains on your confirmed itinerary. On the routes arriving from Kanazawa, skip the morning temple stop if it would rush your ryokan arrival.

Day 1

• Morning: Zenko-ji Temple, then a quick lunch (a station convenience store works in a pinch).

• Early afternoon: the limited express from Nagano Station to Yudanaka.

• Mid-afternoon: check in, then walk up to the Heiwa Kannon or into Shibu.

• Evening: dinner, then the inn's hot spring baths. Book the rooftop bath ahead if you want it.

Day 2

• Early breakfast and check-out.

• The inn's shuttle, the walk and the monkeys.

• Late morning or early afternoon: return to Yudanaka Station, take the train to Nagano, then your onward Shinkansen. Confirm the hotel pickup and leave a buffer before the onward train.

Jigokudani Monkey Park: Your Morning Plan

The park's official guide lists 8:30–17:00 from April to October and 9:00–16:00 from November to March. It can shorten its hours or close without notice because of weather or monkey behaviour. Aim to reach the park at least 30 minutes before closing, and remember that the forest walk comes before that.

Admission changes on December 1, 2026. Until November 30, walk-up admission is ¥800 for adults and ¥400 for children. The official fee-change notice gives the following new prices:

The park lists adults as 18 and over and children as elementary- through high-school students; under-sixes enter free with a guardian. Check the official booking page for your age category and visit date. The official homepage says online-ticket holders receive priority during the December–April winter period. This is not a guarantee that the monkeys will appear or bathe.

Getting to the Monkey Park: Shuttle, Bus and the Final Walk

Three different things are easy to confuse:

1. The inn's shuttle. BIYUNOYADO lists a free shuttle for guests to the Snow Monkey Park parking lot, about 10 minutes by car. This is the inn's own scheduled transport, not a public service. Confirm both the departure and return arrangements with the hotel before you go; do not build your onward train around an assumed shuttle time.

2. The public bus. The park's access guide allows about 15 minutes by bus from Yudanaka Station to the Snow Monkey Park stop, followed by about 35 minutes on foot. Nagaden's Route 20 fare table lists ¥390 for this bus ride. Budget separately for local buses outside the tour itinerary. There is also a direct bus route from Nagano; use the park's access page and current operator timetable for your date.

3. Admission. You pay this yourself, at the gate or online. It isn't listed among the tour inclusions.

Whichever option you take, you still have to walk. From the parking lot it's an unpaved forest trail of about 30 minutes to the park entrance. The park quotes 35 minutes from the Snow Monkey Park bus stop. The park's first-time visitor guide recommends suitable winter footwear; wear snow or rubber boots and consider traction aids when the path is icy. The uneven forest approach also has steps and is not suitable for wheelchairs or pushchairs. Don't count on free Wi-Fi on the trail, so save your return times on your phone before you set out.

Will You See Snow Monkeys Bathing?

Maybe. The park's first-time guide explains that monkeys bathe mainly in the cold December–March period. Even then, not every monkey bathes, and they often care more about eating and socialising. You can't predict when they'll appear. Some days they don't come down at all, and the park says sightings are especially irregular in autumn.

So treat monkeys bathing in hot spring water as a possibility, not a promise. The same goes for snow.

Winter vs the Green Season

Winter (roughly December–March): this gives you the best chance of snow and of seeing monkeys in the hot spring, but also the biggest crowds. Snow can slow trains and buses, and the trail gets icy.

Green season (April–October): the park has longer standard opening hours. The trail is generally easier without ice, although rain can make it muddy; crowds vary with holidays. The monkeys are less likely to be in the pool.

November: winter hours begin, nights are cold, and you can't count on snow.

Shiga Kogen and Ryuoo: Ski Days Beyond Yudanaka

Shiga Kogen ski resort, further up the same road, is one of Japan's largest ski areas. Buses run from Yudanaka Station up to Shiga Kogen, and the timetable changes by season. Ryuoo Ski Park is another ski area accessible from the Yudanaka area. Check the resort's current access information before planning a ski day: a green-season shuttle timetable does not establish winter service.

None of our three routes includes time for skiing, and a single night doesn't leave room for a Shiga Kogen ski day. If you want one, ask us about adding nights.

Choosing Your Route: GR505, GR510 or FG504

All three are full multi-day self-guided itineraries, not standalone Yudanaka ryokan bookings. Each one includes a night at BIYUNOYADO with dinner and the next morning's breakfast. Prices depend on your dates and room type.

The sights named on the tour pages, such as Zenko-ji Temple, Matsumoto Castle and Kenroku-en, are suggestions for sightseeing on your own, not required activities. What we reserve for you is the intercity trains, the taxi days, two luggage deliveries and your hotel nights. There's no guide by default, but a local guide can be arranged as an option. Our staff meet you at the airport on Day 1 with your trip documents, the tickets for the legs we book and a loaded IC card.

FG504 is designed for families and small groups. Its online booking offers triple and quadruple rooms for three or four travellers sharing; it is not the two-person option in this comparison. The tour page confirms available departures, room choices and the current price for your party.

Check dates & prices on GR505, GR510 or FG504. If you have a different party size or want the cities in a different order, send us an inquiry instead.

Common Mistakes to Avoid

• Expecting your Yudanaka inn to give you the Shibu key.

• Thinking the shuttle drops you at the gate. You'll still walk about 30 minutes.

• Wearing trainers on a snowy January trail.

• Expecting monkeys in the pool in October.

• Assuming your room type has its own private onsen.

• Planning a soak without checking the inn's cleaning and bath-changeover times.

• Buying a JR Pass without first adding up your fares.
