What is an onsen? What is the difference between 'onsen' and 'sento'?

Onsen, a word that literally means "hot spring," are natural hot water baths rich in beneficial minerals. There are various types of onsen available, including popular ones like outdoor baths (roten-buro) and indoor baths (noten-buro).

A sento is a public hot bath that typically does not use naturally sourced hot water as with an onsen. In addition, there are "super sento" establishments that offer a more luxurious experience with a variety of saunas, baths, and additional services.

How to spot an onsen

Onsen can be easily identified once you know what to look for. They typically have drapes (noren) at the entrance and are often marked with a symbol that resembles a steam rising from a hot spring (♨) or the character 湯/ゆ.

Sento, on the other hand, may appear similar to onsen at first glance, but they are usually found in urban areas rather than rural ones, since they are not sourced from natural hot springs.

While it is possible to find onsen in large cities, the "hot bath" symbol in an urban setting usually denotes a sento rather than an onsen.

Before entering the facility

The term "onsen" can refer to both the hot spring itself and the accompanying facilities, which are often part of a hotel, resort, or traditional Japanese inn called a "ryokan."

If you plan to visit for a day and have not made a reservation, you can typically purchase a ticket from a vending machine or from a person stationed near the entrance.

It's worth noting that some facilities require visitors to remove their street shoes at the entrance, providing lockers or shelves for storage. In other cases, you may remove your shoes just before entering the bathing area. When in doubt, observe others and ask the staff for guidance.

If you are carrying luggage, you may want to ask the staff whether they offer temporary storage at the reception desk. However, it is generally advisable to avoid bringing large bags unless you plan to stay overnight.

Prepare for your onsen: The changing room

Prepare for your onsen: The changing room
  1. Watch your feet - Upon entering most onsen, you’ll need to take off your shoes. Occasionally that is not the case, but you’ll always need to do so before entering the changing rooms.
  2. Don’t linger by the entrance – Especially if it’s the first time for you to see an onsen, the scene can be quite cool. Make sure, though, that you don’t linger by the entrance. Other people might be needing to get in or out. In Japan, physical contact is usually avoided among strangers, and when people stand by the entrance of the bath area, it feels almost like a violation of other patrons’ personal space (all of this while everybody is wearing only their “birth clothes”).
  3. Prepare to get naked – Clothes, swimming suits, or large towels of any kind are not allowed in the bath area. Don’t fret! No one will notice, and you’ll blend right in! You can leave all your belongings in the lockers in the changing room.

Make sure you bring a small towel with you but don’t worry if you can’t. Onsen usually allow you to use their clean towels - but it may be a paid service. Check at the entrance to the facility.

Finally, note that while you can take a small towel with you into the bath area, you can't enter the water with it.

Before entering the onsen bath itself

It's common practice (and courteous) to wash yourself off before entering the bath, even though you may observe some people just rinsing themselves off. If you brought your own soap, be sure to leave it neatly placed by the shower to avoid inconveniencing other visitors.

Along with all the above, some unwritten rules can often evade those who don’t go to an onsen (or sento) frequently.

  1. No splashing - Once you enter the bath, it's important not to jump, dive, or splash in the water. Simply relax and enjoy the experience, which is sure to be delightful.
  2. Keep your phone out of the changing room - It is common sense not to take pictures or videos, but using your phone in the changing room or the bath area is generally prohibited or, at best, not appreciated. If you must use your mobile device, extend your arms fully within your locker and use it in that position.
  3. Tie your hair neatly - If you have long hair, make sure to tie it up securely after you shower.
  4. Be mindful of your surroundings - Showers in onsen are typically situated close to one another. As a result, it's important to be mindful of not splashing other individuals with water or soap. You'll be grateful when others adhere to the same rule.
  5. More rinsing – Some onsen have a large tub of hot water near the entrance that you can use to rinse yourself before or after entering a bath (and acclimate your skin to the temperature), or anytime you wish. To do so, simply scoop up water with a bucket.
  6. Keep that water flowing – Whenever you move from one bath to another in the onsen, make sure to rinse yourself. Some places also have saunas, and if you use the sauna, be sure to rinse yourself before entering a bath.
  7. Avoid grooming – Although some locals may trim their beards in the bath area while showering, it is generally considered impolite to engage in any grooming activities while in the onsen.
  8. Hey, I’m up here – In order to maintain an atmosphere that is comfortable and enjoyable for everyone, patrons tend to avoid looking (however briefly) at other patrons. It’s hard sometimes to maintain a mile-long stare in front of you when you are in a particularly beautiful place, but make sure you avoid looking (or worse yet staring) at anyone.
  9. Keep the chatting low – Onsen are social environments, but they are also places of relaxation and tranquility. While it's acceptable to chat with friends and family while in the bath, make sure to do so quietly.

Onsen how to and etiquette – after the bath

Onsen how to and etiquette – after the bath
  1. Dry yourself - When you’re done with the bath area, you should not enter the changing room dripping wet. It can sound tricky (and it is), since the only towel you’re allowed in the bath is a very small one, but try to dry yourself best you can with it.
  2. Clean up – If you used buckets to wash yourself, and stools to sit on, make sure you also rinse those before leaving.
  3. Can I sit here? – If there are chairs or benches in the changing area, you can use them only after you’ve put some clothes on.

Onsen Etiquette – FAQ

Onsen Etiquette – FAQ
  • Can I drink alcohol in the bath area? - Drinking alcohol in the bath area is not allowed due to several reasons, including health risks. However, you can drink in the lobby. After you're done, make sure to hydrate with some of the traditional Japanese beverages like coffee and milk or fruits au lait.
  • What if I have tattoos? - Tattoos are often prohibited in onsen and other public places such as gyms, swimming pools, and saunas. However, if you inform the staff beforehand, they may allow you to use the facilities. They may also request you to cover them with a removable sticker. Although attitudes in Japan are changing, some onsen are already accepting tattooed patrons.
  • Can you use onsen when on period? - If you happen to be on your period, women are advised not to go into an onsen bathing area.

On average, onsen water is between 38 and 43 degrees Celsius, but some onsen have baths with temperatures well over 48-50 degrees Celsius.
