The Japanese have been seeking the medicinal properties and spiritual relaxation of soaking in onsen hot springs for centuries. Find out more about the best places to experience onsen in Japan, how to use an onsen bath and etiquettes to observe. After this, you’d be ready for a memorable onsen experience on your next trip to Japan!
Onsen (温泉) are Japanese hot springs. While hot springs can be found wherever volcanic activity is rampant, the Japanese have had a special affinity for the mineral waters. Onsens are plentiful across the country, and most located outside the city limits, which are accessible by train or car, making a weekend getaway affordable.
While the practice of bathing in a hot spring can be found outside of Japan, the process of healing the mind and body through bathing is an integral part of Japanese culture. Like in the scene in the Miyazaki film “Spirited Away,” soaking in an Onsen is enjoyed by the young and old (and spiritual deities too!) It makes appearances in the ancient Japanese texts Kojiki (古事記) and Manyoshu (万葉集) and is central to the Shinto (Japanese indigenous religion) ritual purification of “Misogi” (禊), the hand and mouth purification of “Chozuya” (手水舎), and the Buddhist bathhouse sutra of “Onshitsukyo” (温室経).
Here’s what you need to know before taking an Onsen bath in Japan! We’ve also answered all the questions you may have so you can enjoy this Japanese tradition with ease.
Please note that all photos of Onsen facilities taken by JOC were taken with permission by the facilities.
What is an Onsen?
Onsen (温泉), literally “thermal spring”, is geothermally heated water. The spring water naturally contains minerals and chemicals which are said to cure all sorts of diseases and ailments. The hot spring facilities boast the benefits of the waters, and onsen seekers travel great distances for these benefits for centuries, even today.
In Japan, Onsens are heavily regulated by the Onsen Law, enacted in 1948 by the Japanese Ministry of the Environment. This law requires the identification of 19 different minerals and chemicals, the spring water to be 25 degrees Celsius or above, and to contain certain levels of hydrogen ion, fluorine ion, sulfur and the like. The ministry officially recognizes 2,300 onsens across the country, but many more natural and untouched springs exist.
Some are stand-alone facilities, some are in ryokan (Japanese inns). The price can range from the high end to the low, and can also fluctuate with tourist season. You do not necessarily need to stay at an Onsen ryokan to experience it; some allow day use for non-guests and many Onsen areas offer passes to multiple Onsen facilities, so you can Onsen hop!
There are non-Onsen baths called Sento (銭湯), which are affordable and accessible. While also communal baths, it is usually just heated water and is for daily use. If you’re strolling around a residential area, you may spot a sign with the Chinese character “湯” (hot water) or the Hiragana “ゆ”. Feel free to casually drop in for a bath and eye-opening experience!
Where Can I Experience the Best Onsen in Japan?
With so many different styles and varieties of Onsen, where should you start? Here you’ll find the best regions for Onsen you can experience in Japan. Should you be traveling nearby, definitely take a day or two to stopover.
1. Noboribetsu Onsen (登別温泉), Hokkaido prefecture
Meaning “Milky White River” in the Ainu language (an indigenous people of Hokkaido, the Kuril Islands, and Sakhalin), the area of Noboribetsu Onsen was first discovered and frequented by the Ainu for its healing properties. It’s also referred to as the department store of the hot springs, as you can find seven different types of minerals, and therefore seven different types of hot springs.
2. Kusatsu Onsen (草津温泉), Gunma prefecture
A 3-4 hour bus or train ride north of Tokyo, the lively town of Kusatsu is famous for its sulphuric waters and free-flowing hot springs. When visiting, you must check out the impressive Yubatake (湯畑) to see 4,000 liters of hot water and steam gushing out of this one source per minute, where the spring water flows through and into the nearby Onsen facilities.
3. Atami Onsen (熱海温泉), Shizuoka prefecture
Located just 35 minutes away on the bullet train from Tokyo, Atami Onsen makes an ideal day trip from Tokyo. The scenic ocean resort of Atami has been catering weary bodies for over 1,000 years. Loyal patrons include the first Edo shogunate Tokugawa Ieyasu, who is said to take casks of the spring water back to Edo (now Tokyo). The waters are famous for its sulfate and salt-rich properties.
4. Gero Onsen (下呂温泉), Gifu prefecture
Just an hour away from Hida Takayama and Nagoya, the hot springs of Gero Onsen are colorless alkaline-based. The springs are also nicknamed the “beauty hot springs” and are said to improve the skin. The minerals are mild, so it’s perfect for first-timers or those with sensitive skin. There are free Onsen facilities around town, one that is mix gender AND open-air, right in the center city under a bridge! You can dip your toes into Fusenchi (噴泉池), or for the more adventurous, change into a bathing suit and jump in.
5. Arima Onsen (有馬温泉), Hyogo prefecture
Squeezed between a mountainous region, but an easy getaway for Osaka and Kobe residents, it is one of the most famous and prestigious Onsen region in the country. Here, you’ll find two types of hot springs: Kinsen “gold water” (金泉) has a reddish-brown hue due to its high iron content and is said to be good for hypersensitivity, skin ailments, and muscle pain. The translucent Ginsen “silver water” (銀泉) contains radium and carbonate and is said to cure various muscle and joint ailments.

6. Beppu Onsen (別府温泉), Oita prefecture
Located in southern Japan just 2 hours from Fukuoka, Beppu Onsen boasts the highest concentration of hot spring sources and the highest yield of hot spring water in Japan. Walking around this quaint town, you’ll see thick clouds of steam rising from drains and air vents. Take a tour of the eight “Blood Pond Hells” (血の池地獄), frightful natural ponds gushing out 100 degrees Celsius fumarolic gas and thermal mud, resulting in a hair raising blood-red or cobalt blue water and hot steam.

There are many that couldn’t fit in this article and more hidden gems scattered across the country. For hotels and Onsen resorts, I suggest exploring TripAdvisor or Japan-Guide to start; part of the fun of traveling is the planning! With the 2020 Summer Olympics as well as the exponential growth of travelers from abroad, Onsens and the tourism industry is constantly building and renovating to accommodate the demand. Thus, it’s hard to recommend a handful of Onsen ryokan, so hope your search is fruitful!

Are there Onsens in Tokyo?
If you’re visiting Tokyo but don’t have time to take a detour to an Onsen, why not spend an afternoon in an urban oasis?
Ooedo-Onsen Monogatari (大江戸温泉物語)
Like an indoor amusement park in a traditional Japanese summer festival setting, you can easily spend an entire day soaking in the many baths and checking out the activities within the facility. At the entrance, you first change into a Yukata (cotton traditional Japanese robe) and can stroll around munching on Japanese snacks or play Japanese carnival games. It’s also family-friendly as well! It’s conveniently located in Odaiba, and the facility offers free shuttles to major train stations.
Treat yourself to this luxurious spa and Onsen facility after a long day of walking and sight seeing. Located in Tokyo Dome City, Spa LaQua is more catered towards an adult crowd, (entry is for children 5 and up), but it’s perfect for those seeking peace and tranquility. For an additional fee, they offer massages, pedi/manicures, as well as facial and body treatments.
A recent newcomer to the Tokyo Onsen scene, it’s located right smack in the center city of Shinjuku. Offering a spectacular city scenery from the Onsen and the rooms, the hot spring waters are brought over from Hakone, a popular hot spring area in Kanagawa. They do not offer day use of the Onsen, so you must stay here to use their facilities.
How to Use an Onsen Bath
Ready to hop in? Here’s your step-by-step guide on how to use an Onsen in Japan:
The Changing Room

Onsen Etiquettes & Rules
Since Onsen is a communal experience in Japan, there are some rules of etiquette you will have to observe:
Q: I have tattoos! Can I use Onsen?
This is probably the most asked question from foreigners when comes to using an Onsen in Japan! The reason why tattoos are not allowed in Onsen is that tattooed people have been traditionally linked to the Japanese underground society. By banning tattooed patrons, the Onsen facilities are able to shun these bathers. It is not a disregard of the craft.
The good news is the Japanese society has incrementally loosened its tattoo ban to accommodate the influx of foreign tattooed tourists in recent years. However, some that may still continue the policy.
My advice is to check the website or call beforehand to ask about their tattoo policy. Or find tattoo-friendly Onsen here or here (Use chrome to translate). If your tattoo is small, cover it up with a bandaid. You can also choose to stay at a Japanese inn with a private Onsen attached to your room. Or find a place where you can rent out an Onsen for yourself.
Q: What is the small towel used for and is it necessary?
The small towel that may be given to you or available for purchase is for two purposes; to wash your body and to cover up your private areas when entering and exiting the Onsen. The towel is not necessary, but more for modesty use. If you stay at a ryokan, most ryokans expect guests to keep the small towel and bring back to their room to dry.
Q: Can I still use the Onsen if I have an injury/sickness/medical condition?
If your injury is an exposed wound that may become infected or contaminate the waters, you must avoid the Onsen. If you have a medical condition or are feeling under the weather, ask your healthcare provider in advance. The water temperature can be hotter than you expect, so don’t take the risk!
Q: Can I use Onsen when pregnant or when menstruating?
Similar to the above, ask your healthcare provider in advance. If you are menstruating, avoid the Onsen even if you have a tampon/menstrual cup on.
Q: Can I bring small children of the opposite gender?
It could be a scary feat for small children to bathe alone without a familiar face in sight! Some places may explicitly state the criteria of bringing children of the opposite gender (e.g. under xx cm/xx age). You could always opt for staying at a Japanese inn with an Onsen attached or rent out a private Onsen for the whole family to enjoy.
Q: Do I really have to strip down naked?
Yes, and no bathing suit is allowed. You must remove all articles of your clothing before entering. If you’re shy of getting down to your birthday suit, opt for staying or renting out a private Onsen.
There are two exceptions for covering up. First, if you enter a Kon-yoku (混浴), mixed-gender Onsen. In this case, you are allowed to fully wrap yourself with a bath towel. The other condition is if you soak in a river with natural hot spring water, which entails bathing in the outdoor wilderness.
Q: I’d like to take photos of the Onsen/myself bathing. Can I bring my camera or smartphone?
Absolutely not! Even if you vow not to take pictures of other bathers, this is a privacy infringement and will get you into serious trouble if caught. If you insist on taking photos, opt for staying a room with private Onsen or renting out an Onsen for your private enjoyment.
Q: What should I bring?
Many facilities offer towels and provide shampoo/soap. If not, they are most likely be available for purchase at the entrance. Hairdryers and face lotions are most likely provided as well. You can just bring a change of clothes, so no need to come prepared! If you’re staying at a Japanese inn with an Onsen, you can change into the Yukata (cotton Japanese robes) provided in your room, or come in normal clothes.
Q: What other things should I avoid before entering an Onsen?
You should avoid going immediately after a meal, drinking alcohol, or after an intense workout. The hot water will raise your body temperature and stimulate blood flow, so give yourself adequate time to settle down before dipping in. The floors can be slippery, so you should always be cautious and never run.
Lastly, don’t forget…
Japanese Onsen is a truly unique experience for any visitors to Japan. While all these etiquette rules can be overwhelming, I hope this has convinced you to take a dip and immerse yourself in this invigorating custom. Just remember to be courteous and mindful of others, and also listen to your body and take breaks in between to avoid overheating. After all, an Onsen is a shared space where bathers come to relax and indulge!

Awesome! I loved visiting Onsens in Japan- mostly in Hakone. It’s an experience I haven’t found anywhere in the US except for 10,000 Waves in New Mexico.
Hi Noah! Hakone does have excellent and renown onsens, hope you’re able to check out other regions during your next visit to Japan. I haven’t experienced hot springs outside of Japan myself, but am curious what that’s like. Thanks for your comment 🙂
When I was planning a visit to Japan, I found a lot of information concerning tattoos, but none concerning piercing. In other countries I haven’t worried about piercings in public baths but that is because in other countries there is no ban on tattoos. In western countries there is a strong correlation between having tattoos and having piercings so I think of them as related issues.
What are the general rules concerning body piercings in areas normally covered by clothing, such as the navel, nipples, or genitals? And what about visible piercings, such as the nose, lips or eyebrow? I ended up not going to an onsen because I couldn’t find any information about piercings. While I could remove my piercings it requires some planning and it isn’t something I could comfortably do in an onsen changing area.
Hi Ann! That’s true, I don’t see direct mentions of body piercings at onsen facilities. Body piercings aren’t common in Japan, and not affiliated with the underground society, which may explain the lack of rules. I would suggest treating piercings like accessories, which should be removed before entering an onsen. Thanks for your comment!
The tattoo issue seems to come up a lot for foreigners, and I will say the following from experience (tattooed white dude who’s been to dozens and dozens of onsen without a problem):
‘NO TATTOOS’ is onsen-speak for ‘No Yakuza’. (Yakuza are the Japanese version of the Mafia). I suspect the onsen operators anticipate they might open themselves to confrontations if they put up a ‘No Yakuza’ sign, so as most Yakuza are tattooed, they simply go for the ‘No Tattoos’ sign instead.
Therefore, as long as you aren’t ethnically Asian* so as to be mistaken for a Japanese person, I can’t imagine you’d have a problem. Last I heard the Yakuza doesn’t typically allow non-Japanese to join their ranks. I’ve had my tattoos pointed out by fellow onsen patrons in the past at being in violation of the rule, albeit seemingly in jest, and I’ve simply pointed out the above:
“Come on, we all know that rule means ‘no Yakuza’. Do I look like a Yakuza to you?”
“Haha, good point!” is generally the response I’ve gotten.
So in a nutshell, if you’re a tattooed person who’s hesitant to visit onsen, I would say don’t worry at all. Nobody is gonna give you a hard time. Soak away!
*Even if you ARE Asian and tattooed, and they assume you’re Japanese, I’d bet they STILL wouldn’t say anything to you; they’d probably be concerned that you may actually be a Yakuza who doesn’t give a hoot about their little tattoo rule, and therefore might also not give a hoot about throwin’ someone a beatin’ for trying to kick them out of an onsen.
Hi Brian! Thanks for sharing your story as a tattooed onsen seeker! I haven’t heard cases of onsen facilities shunning away Yakuza patrons, they’re probably too scary to anyways ><
Three years ago, I was lucky enough to visit an onsen just at the foot of Mount Fuji. It had snowed the night before and the landscape was gorgeous. I remember relaxing in the Onsen with a towel on my head and watching the snow clouds blow off the top of Mount Fuji. Truly it doesn’t get any better than this.
I do have a small tattoo but I simply covered it up with a large Band-Aid and nobody cared. I would not leave Japan without an onsen experience and the next one for me I hope will be in Hokkaido.
Hi Mary! Your episode of soaking in an onsen with Mt Fuji in the background + snow is romantic! And thank you for sharing your story as a tattooed onsen seeker! Hope you enjoy your onsen in Hokkaido!
I loved your article on onsens! I am visiting Kyoto October 2020. Are there any private onsen hotels there?
Hello Christine! Thanks for reading! I do not know of the onsen scene in Kyoto, so I suggest looking up TripAdvisor or search on Google. If there isn’t one in the city, there should be in the outskirts. Hope you find a wonderful place to experience an onsen 🙂
Great, comprehension article. Lots of wonderful memories of visiting onsens with friends when i lived in Japan many years ago. Favourites were the outdoor onsen by a river in Nikko and also ones in Hakone. Absolute must do when visiting Japan, preferably in Autumn or Winter. One thing not to do is drink too much alcohol before going into an onsen – the alcohol goes straight to your head and a friend on mine passed out.
Hi Manoja! I agree, autumn and Winter are the best season for onsen, especially if its outdoors for you to soak in the beautiful foliage or winter landscape. Plus, there’s nothing so satisfying as dipping into a hot bath when it’s cold out. And yes on the alcohol, you may not think you had that much to drink until you start feeling the blood rush to your head… Hope your friend was alright!
Thank you so much for this article! My friend and I are hoping to visit Japan in 2020 and one of our goals is to spend a couple days or two in an onsen resort! It was especially helpful to know about the different minerals in many popular locations…I have a nickel allergy and sensitive skin so knowing this info is extremely useful! I do have a quick question…I have heard some onsens are not open to foreigners…is that true, and if so, how do check that when booking? Thank you!
Hello Grace, thanks for reading! I hope you and your friend find a suitable onsen resort that won’t irritate your skin! Do check out the facilities in advance and call/check the website if unsure. As for the policy of non-foreigners, I have never heard of such cases…don’t think onsen facilities could explicitly state such a racist policy. Perhaps super remote onsen facilities that primarily cater towards the locals and have hardly any tourists may be a bit surprised to see non-Japanese patrons but I’m sure they won’t kick you out just because of that! Especially with the upcoming Olympic Games, most onsen facilities are expecting non-Japanese bathers, so I don’t think you need to be worried about that.
This article came at the most convenient time! I am currently in Hakone, waiting for my time slot for a private onsen at the ryokan I am staying at and was unsure of the etiquette that was expected! I’m still confused about the towel situation since I have one big towel and one little one but don’t know where to dry the big one… 🤔 Either way, I’m super excited!
Hi Eilene! Glad to hear that this post helped you navigate through your onsen experience! As for the large towel, unless there’s a used towel receptacle, take the towel back to your room to hang. Hope your onsen experience in Hakone was amazing!
I don’t think I’ve ever been to an onsen but I do remember going to a public bathhouse on Okinawa when I was 4yo. Men on one side. Women and children on the other of a large hanging screen. It looked like a large rectangular steaming pool. I remember it was very warm and felt great!
Hello Kim! Your description sounds like a typical neighborhood Sento (public bathhouse). Amazing how you remember your experience even today! It must have been quite the eye opener. Thanks for sharing your story 🙂
This is very really unique helpful information.I learn so much from you as well! Thank you so much for sharing your helpful information. Keep it up.
Hi Mahidua, thank you for your kind comment! Hope this will be helpful for your next onsen experience.
I am someone who is not on the thin side, and planning to visit onsen. I know all the rules but struggling with the notion that my weight and appearance might inconvenience other onsen visitors, should I just rent out a private onsen?
Hi Maria! There are all sorts of people visiting an onsen, but the thought of getting naked in front of strangers may make you wary. In general, other bathers do not stare at others (not considered good manners) but if you do feel shy, you could rent a private onsen for yourself. I wouldn’t worry that you may be inconveniencing others, the experience should be about you!
Onsens is my fav place in japan, 2 year ago i went and it was extremely awesome place but little bit expensive if compare to other cities.
Over all enjoyed a lot. Thanks for sharing good photos.
Hi Ravin! Thanks for your comment! Hope you’re able to visit an onsen during your next trip to Japan!
We stayed at several ryokan with our children about 12 years ago. Some had private and family baths but one had a communal one. After washing up, my daughter and I headed to the bath. There were 3 Japanese ladies who scurried out as fast as they could. I have always felt badly that they had to cut their bathing short and was never sure if they didn’t want to see me or didn’t want me to see them. Now I realize I had a little camera with me since I did take a photo of my 8 year old daughter in her yukata once we were all alone. Perhaps in the end it was the camera that drove them off rather than the sight of a very pale foreigner…
Hi Lisa! I hope you and your daughter didn’t frighten the bathing ladies, although a camera sure would! Hope you were able to snap a few photos of your daughter in a yukata! Thanks for sharing your story 😀
Yayoko, I am pretty sure the camera wasn’t out in the open and that they were moving aside to let us use the pool without us having to look at them , 3 elderly ladies. I did privately snap a few cute photos of our daughter, age 8, in her yukata with the back drop of a wall tiled in underwater scenery.
