Everything You Need to Know About Japanese Hot Springs

1. What is an onsen?

An onsen is a natural hot spring bath. Japan’s volcanic landscape produces an abundance of geothermal springs, many of which are rich in minerals believed to have therapeutic properties. Onsens can be found indoors or outdoors (rotenburo) and often feature breathtaking views of nature.


2. Do I need to be completely naked in an onsen?

Yes, bathing in an onsen is traditionally done nude. Swimsuits and clothing are not allowed, as cleanliness is a top priority. Gender-segregated baths provide privacy, and most people quickly feel comfortable once they adjust to the custom.


3. Are tattoos allowed in onsens?

Many traditional onsens restrict access to people with tattoos due to historical associations with organized crime. However, attitudes are gradually changing, and tattoo-friendly onsens are becoming more common. If you have tattoos, it’s best to research in advance or consider using tattoo cover stickers.


4. How should I prepare for my visit?

  • Bring towels: A small towel for washing and a larger towel for drying. Some facilities offer rentals or provide towels for an additional fee.
  • Pack toiletries: While most onsens provide basic amenities like soap and shampoo, it’s a good idea to check beforehand.
  • Research rules: Some onsens may have specific policies, especially regarding tattoos, photography, or noise levels.

5. What happens in the changing room?

In the changing room, you’ll store your belongings in lockers or baskets. Undress completely and leave your larger towel here. Take only your small towel and toiletries into the bathing area.


6. Do I need to wash before entering the bath?

Yes! Thoroughly washing your body is a vital part of onsen etiquette. Use the provided shower stations to clean yourself from head to toe, and rinse off all soap and shampoo before entering the bath.


7. Can I bring my phone or camera?

Photography is generally prohibited to respect the privacy of other bathers. It’s best to leave your phone in your locker or designated storage area.


8. Is it okay to talk in an onsen?

Quiet conversations are usually acceptable, but keep your voice low. Onsens are places of relaxation and tranquility, so avoid loud or disruptive behavior.


9. Can children visit onsens?

Yes, children are generally welcome at onsens, but they should follow the same rules as adults, including washing before entering the baths. Parents should supervise children closely to ensure they respect the peaceful atmosphere.


10. What if I have long hair?

Tie your hair up to prevent it from touching the water. Many onsens provide hair ties or clips for this purpose.


11. What types of baths can I expect?

Onsens often feature multiple baths with varying temperatures and mineral compositions. Some may include cold baths, steam rooms, or even specialty baths infused with herbs or sake.


12. What should I do after bathing?

Dry off thoroughly before leaving the bathing area to avoid dripping water in common spaces. Many onsens provide rest areas where you can relax and rehydrate with water or tea.


13. Are there private baths available?

Yes, many onsens offer private baths (kazoku buro) for families, couples, or individuals who prefer more privacy. These can usually be reserved in advance.


14. What if I don’t speak Japanese?

Many onsens cater to international visitors and provide signs and instructions in multiple languages. Staff are often accommodating and used to helping non-Japanese speakers.


15. How much does it cost to visit an onsen?

Prices vary depending on the location and amenities, but most onsens charge between 500 and 2,000 yen. Some high-end or private facilities may cost more.
