What shapes a visit to Japan
Winter is when Japan's hot springs make the most sense. Add the Jigokudani snow monkeys in Nagano, the yumomi paddles in Kusatsu and a basket of onsen tamago, and a winter trip turns into a run of specific experiences, not one long soak repeated in different towns.
My own winter onsen thinking started closer to home, though, and without any snow at all.
On a weekday morning at an Arashiyama onsen in Kyoto, I watched mist lift off the river while the water held me still. Through the fence around the outdoor bath I could see the bamboo forest catching the early light. A temple bell sounded somewhere in the distance and nobody else made a sound. That morning convinced me that the baths worth crossing a city for sit outside its centre, and a winter trip to Nagano and Gunma follows the same logic: you travel out to where the water is.
Before any of it, spend ten minutes with the JNTO guide to onsen etiquette and bathing rules.
Snow Monkey Park, Soba Lunch and Shibu Onsen Tour: what the itinerary covers
If I had one winter day in Nagano and wanted both the monkeys and a real onsen town, this is the format I would pick. It pairs the wild snow monkeys at the park with a visit to Shibu Onsen, a traditional hot spring town, and a soba lunch in between.
The monkeys are wild animals, so treat a sighting in the pool as something the day may give you, not something the ticket buys.

Planning winter onsen experiences in Japan
Three winter moments justify the effort: monkeys soaking at Jigokudani, the yumomi paddles in Kusatsu, and eggs cooked by the ground itself.
Nagano's Jigokudani snow monkeys have been bathing in the onsen since 1963 when a local innkeeper built the first pool; they now draw 100,000+ visitors annually. Crowds are part of the picture, so book a morning entry: local advice holds that the monkeys stay in the water longest on cold mornings. Check the Japan Meteorological Corporation for snow forecasts before you commit to a date, and see my Nagano page for how I would base myself there.
Kusatsu Onsen's Yubatake (hot water field) produces water naturally at 51-94°C; the timber troughs visible in the town centre cool it to bathable temperatures before distribution to ryokan and public baths. Kusatsu's yumomi performance, the traditional water-cooling ceremony using large wooden paddles, is a 400-year-old practice originally developed because the source water was too hot to bathe in directly. My Kusatsu guide covers the town in more depth.
Onsen tamago (eggs slow-cooked in hot spring water) are a common snack. In Beppu's Kannawa district in March 2022, a local woman handed me a wire basket with two eggs and a sweet potato in it. She pointed at a steam vent in the pavement, hissing at boiling heat, and I lowered the basket in, waited a few minutes, and pulled out perfectly cooked onsen tamago, though the sweet potato took far longer. She charged me a few coins and told me the vent has been used this way since the Edo period.

What Surprised Me About Japan
The surprise was how social a bathing town can feel when the whole place is built for walking between baths.
In October 2023 I checked into a ryokan in Kinosaki Onsen, Hyogo, in the afternoon, changed into the provided yukata (a light cotton robe) and walked straight out into the street. The entire town was in yukata, couples and families and groups of friends all shuffling between the seven public baths in wooden geta sandals. The clicking of geta on pavement became the town's soundtrack for me. The fifth bath was empty by the time I reached it, and the seventh, Satono-yu, had a rotemburo with steam drifting up into the autumn night sky.
My takeaway from Kinosaki: skip the ryokan with a private bath, buy the day pass and hop between the sotoyu (public baths) until your legs give out.
The pauses surprised me too. Most onsen have a rest area with tatami mats and vending machines after bathing. Buy the milk in a glass bottle, since that is the tradition, sit down and let your body settle before you head back into the cold.
The Japan Onsen official cultural tourism site helps you compare regions and inn styles, and my ryokan guide explains what to ask before booking.
Planning the visit well
Go to the rotemburo early in the morning or later in the afternoon, carry coins and cash, and reserve any private bath at the same moment you reserve the room. Weekday afternoons from Tuesday to Thursday are the quietest.
Private onsen (kashikiri-buro) at ryokan book in 50-minute slots and cost ¥2,000-5,000 extra on top of the room rate. Weekend slots book out weeks ahead, so reserve the bath when you reserve the room, not at check-in.
Pack a warm hat for the walk between the indoor and outdoor baths, and drink water before and after bathing, because onsen can dehydrate you quickly. If you feel dizzy or nauseous, get out immediately and cool down.
Tattoos need a direct question, not an assumption. Email the ryokan in English before booking; small family-run places may say yes to a polite inquiry even when their website says no.
For a short Nagano window, Explore Jigokudani Snow Monkey Park with a Local Guide is a focused guided walk to the monkeys with nothing else bolted on. Choose it if time is tight and the monkey park is the single thing you came for.

Before you visit
My own mistake was treating a famous ritual as a tourist show.
Kusatsu Onsen, Gunma, February 2024. The yumomi performance was listed in every guidebook, so I assumed it would be touristy and skipped it on my first day. On the second day I wandered in ten minutes late to find six women in traditional dress singing a work song in the local dialect while churning scalding water with metre long wooden paddles. The room was a working hot spring hall, not a theatre, and steam filled the space so thickly my glasses fogged instantly. By the time the water was cool enough to touch, I realised the four hundred year old technique was not a performance at all but something still plainly necessary.
That trip also showed me why Kusatsu needs a night. A day trip from Tokyo spends most of its hours in transit and misses both the evening Yubatake lights and the morning yumomi. The Japan National Tourism Organization is the place to check regional transport before you fix your route.
Bathing is always naked, so leave the swimwear at home. Wash at the stool before entering, pull the shower head out of the bucket before you turn it on, and keep the small tenugui towel on your head or outside the water. Bring cash for rural baths that may not take cards, 100-yen coins for lockers, and confirm your ryokan's onsen is open if you are booking a Monday or Tuesday, because smaller baths may close one weekday for cleaning.

Frequently Asked Questions
Are the Jigokudani snow monkeys guaranteed to be in the hot spring?
No, they are wild animals and no tour can promise they will be in the pool when you arrive.
Can I see Kusatsu's yumomi and Yubatake without staying overnight?
You can see the Yubatake in daylight, but you will miss the evening lights and the quieter hours after day visitors leave.
Can I use a winter onsen in Japan if I have tattoos?
It depends on the individual bath or ryokan, and their policies change.
What is a kashikiri-buro and who should book one?
A kashikiri-buro is a private bath at a ryokan that your group reserves for a set slot.
What should I bring for a winter onsen day?
Bring your own tenugui towel, because rental sets do not always include the small towel you use in the bath.
