What shapes a visit to Japan
Choosing an onsen region in Japan starts with one question: what do you want the water to do for your trip? Hakone covers access, Beppu covers sheer volume, Nagano brings snow and wild monkeys, and Kinosaki takes the stress out of tattoos.
Hakone is Japan's most accessible onsen destination from Tokyo. That one sentence explains why my Hakone guide is where I send first-timers who have a single free day. A far region is still a better fit if your only goal is snow on the rotemburo (the open-air bath) or a town built around bath hopping. For train routes and regional planning, the Japan National Tourism Organization (JNTO) keeps its transport pages current.
Tokyo itself surprised me. My flight landed at Narita in the evening and it was close to midnight by the time I reached Shinjuku. Thermae-Yu was still open, so I went up to the rooftop rotemburo above Kabukicho, with the Tokyo skyline lit up around me. The water was scalding and the night air was close to freezing. A salaryman next to me fell asleep sitting upright on the underwater bench, and the staff woke him gently a little later.
Traverse Outer Rim of Hakone Caldera and Enjoy Onsen Hiking Tour: A Rim Walk With a Bath at the End
This tour follows the rim above the Hakone caldera and ends in an onsen. I'd point geology-minded walkers here before I'd suggest another ropeway queue.
I arrived in Hakone on a Tuesday morning in heavy June rain. The outdoor sights were pointless, since visibility from the ropeway was down to almost nothing. I went to a small sento near Gora station instead and found only three other people there. A sento is a plain neighbourhood public bathhouse, and this one had a tin roof. The rain on it was loud and steady, and the time I spent there beat any clear-day ropeway ride.
That day taught me to hold a caldera walk loosely. Book it with a spare day on either side, and if the forecast turns, switch to the baths. Leave this tour off your list if you want a gentle stroll between baths.
Planning Choosing the Right Onsen in Japan
Beppu has Japan's largest volume of hot spring water output. In the 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. 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.
My Beppu guide covers the town in more depth. Beppu is the wrong pick if snow on the bath is the whole point: the seasonal notes I work from say Beppu is warmer year-round.
Nagano's Jigokudani Monkey Park features wild snow monkeys bathing in outdoor onsen. In winter, snow plus an outdoor rotemburo is the classic onsen experience, and Nagano is the prime region for it. Check the snow forecasts at the Japan Meteorological Corporation before you commit to mountain roads.
2 Hour Onsen Calligraphy Experience: A Hands-On Session Between Baths
This workshop is built around onsen water themes. You work with ink and a brush and take your finished piece home. Plan your bath visits separately, because the session doesn't include bathing.
Pass on it if every free hour of your trip should be spent in the water. Culture-minded travellers who like making something with their hands are the people I'd send.
What Surprised Me About Japan
In January 2023 I was planning a stay at a small ryokan in rural Nagano. I sent a polite email in basic Japanese explaining that I had a small tattoo and asking whether I could use the bath. The reply came back within the hour: no problem, please use it later in the evening when there are fewer guests. They did not even charge me extra.
If you'd rather not ask at all, Kinosaki takes the question away. Kinosaki Onsen in Hyogo Prefecture has seven public bathhouses (sotoyu), and as of 2025, all seven are confirmed tattoo-friendly. My Kinosaki guide explains how the town works on foot. Tattoo policies change, so check again close to your travel date.
Kagoshima has natural sand baths heated by volcanic activity. Mixed-gender onsen (konyoku) still exist in remote areas but are rare. Treat it as something you might come across, and read the Japan Onsen official cultural tourism site to compare onsen types and ryokan by region.
Planning the visit well
Go to the rotemburo early in the morning or late in the afternoon, carry coins and cash, wash thoroughly before you get in, and learn the few rules that protect other bathers. JNTO's onsen etiquette and rules page lays these out clearly and makes good reading on the train.
The small towel, the tenugui, is for washing and not for modesty. Everyone in the bath is naked, and the towel stays out of the water, folded on your head or set aside. At a ryokan, wrap your yukata (cotton robe) left side over right, because right over left is for funerals.
Drink water before and after bathing, because onsen can dehydrate you quickly. If you feel dizzy or nauseous, get out at once and cool down, and stay out of the bath after heavy drinking.
Kurokawa is the region for bath hopping. Many onsen in Kurokawa (Kyushu) sell a wooden 'onsen-hopping pass' (¥1,300) that gives access to three different ryokan baths. My Kurokawa guide covers how to plan a hopping loop.
Spring cherry blossom season makes onsen towns busy, so book ryokan well ahead. June is rainy season and brings fewer crowds. Autumn foliage is peak season, and Hakone gets especially crowded. My seasonal onsen guide goes through each window month by month.
Before you visit
Before booking, I wish I had checked the practical details more carefully than the town itself. Confirm the tattoo policy in writing. Find out whether the rotemburo is private or shared, which weekday the bath closes for cleaning, and whether the place takes cards.
Golden Week (late April-early May) is the busiest period for onsen towns. If you can't commit to an overnight stay, choose Hakone for its Tokyo access and save the distant regions for a longer trip.
In the bath itself, leave the swimwear behind, because bathing is always naked. Wash at the stations first, keep your head above the water, and never take photos in the bathing area. Carry cash too, since rural onsen may not accept credit cards.
A ryokan with a private onsen can still enforce tattoo rules in shared spaces such as the dining room, so ask about the whole property. Bring waterproof tattoo cover bandages from home, because the sizes sold in Japanese pharmacies are limited.

Frequently Asked Questions
Can I use an onsen in Japan if I have tattoos?
Kinosaki's public bathhouses are the most straightforward choice on this list, and elsewhere a polite message sent ahead can get you a yes. Call ahead or check the bath's website first, and don't assume either way.
When should I visit the snow monkeys at Jigokudani?
Book a morning entry, because the monkeys stay in the water longest on cold mornings.
Is Beppu a good winter onsen choice?
February is a good month for Beppu: the winter crowds have thinned, and cold air makes the outdoor rotemburo more enjoyable. You're unlikely to get the snowy scene you'd find in Nagano.
Which holiday periods besides Golden Week get crowded?
New Year is a peak travel window for onsen towns, so book early if your trip falls over the holidays.
What should I bring home from an onsen town?
Onsen manju, the local steamed buns, are the classic souvenir. After your bath, look for milk in glass bottles at the vending machines, which is a long-standing onsen tradition.
