The Complete Guide to Bathing in Japan: From Beginner to Pro, Soak Like a Local Without the Awkwardness

For many first-time visitors, going to a Japanese bathhouse can feel a little nerve-wracking: Do I have to be completely naked? Where do I put my towel? How long should I stay in? What if I walk into the wrong bath?
Don’t worry — this practical guide covers everything you need to know so you can relax and enjoy the experience, going from nervous newbie to confident pro.

I. Where to Bathe? Onsen vs. Sento

Onsen (Hot Springs)
•    Water source: Naturally occurring, mineral-rich hot spring water, believed to have health benefits.
•    Locations: Found in tourist areas, mountain resorts, or hot spring hotels.
•    Atmosphere: More of a leisure and resort experience.
Sento (Public Bathhouse)
•    Water source: Regular tap water heated artificially.
•    Locations: Common in residential neighborhoods, part of local daily life.
•    Atmosphere: Everyday, down-to-earth — a glimpse into how locals live.
Common Types:
•    Public Bathhouse: The most traditional style. Men’s and women’s baths are separate.
•    Rotenburo (Open-Air Bath): Outdoor baths where you can soak while enjoying natural scenery.
•    Kashikiri-buro (Private/Family Bath): Reserved for couples, families, or those not comfortable with public bathing.
•    Higaeri Onsen (Day-Use Onsen): Bathing without an overnight stay — flexible and convenient.

II. What to Bring? Your Pre-Bath Checklist

Towels
•    Small towel: Used to cover yourself a bit or wipe sweat. (⚠️ Never dip it into the bathwater.)
•    Large bath towel: Usually not provided, used to dry off afterwards.
※ Some onsen or sento rent or sell towels (usually for a fee).
Cash/Coins
Many sento only accept cash. You may need coins for tickets, towel rental, or drinks.
Toiletries
Basic shampoo and body wash are often provided but not high quality. Bring your own skincare — skin can get dry after soaking.

III. Step-by-Step: How to Bathe Like a Local

1.    Remove Shoes
Take off your shoes at the entrance and put them in a shoe locker.
2.    Buy Ticket or Pay
In sento, buy a ticket from the vending machine. In onsen hotels, show your room key or card.
3.    Changing Room
Go into the men’s bath (男湯) or women’s bath (女湯). Undress completely and store your clothes and belongings in a locker. Keep the locker key on your wrist or ankle.
4.    Wash Before Entering
Bring your small towel into the shower area. Sit on a stool and wash thoroughly with soap and shampoo. (⚠️ Rinse off all the foam.)
5.    Soaking in the Bath
•    Rinse your body with hot water before entering to adjust to the temperature.
•    Do not put your towel in the bath. Place it on your head or leave it by the edge.
•    Be quiet — no swimming, scrubbing, or loud conversations.
•    Start with 5–10 minutes, then take a short break.
•    If you have long hair, tie it up so it doesn’t touch the water.
6.    After the Bath
Wring out your small towel and wipe excess water before heading to the locker room.
Use your large towel to dry off completely before getting dressed.
7.    Rehydrate
Most bathhouses have vending machines near the exit. It’s a tradition to grab a bottle of coffee milk or fruit milk after bathing — the “soul of Japanese bathing!”

IV. Bathing Etiquette & Things to Avoid

2.    Tattoos: Many public baths don’t allow visible tattoos. Look for “Tattoo Friendly” places, or cover with concealer/patches.
3.    No Photos: Cameras and phones are strictly prohibited in baths and changing rooms.
4.    Quiet Atmosphere: Keep conversations low and avoid splashing around.
5.    Health & Safety:
•    Drink water before and after bathing.
•    Start with lower-temperature baths, soak no longer than 10 minutes at a time.
•    Avoid onsen if you have heart conditions, high blood pressure, or have been drinking.

V. Frequently Asked Questions

Q: Do I need to bring cash?
A: Yes, bring some coins and small bills. Sento usually only take cash. Hotels may accept cards, but ticket machines and vending machines are cash-only.
Q: Should I remove jewelry?
A: Yes. Metal heats up in hot water, and wearing glasses, watches, or accessories is considered unhygienic.
Q: Can I wear glasses in the bath?
A: Not recommended. The steam fogs them up and they can slip off.
Q: What if I don’t speak Japanese?
A: Ticket machines often have Chinese/English menus. For drinks or milk, just point — staff are used to it.
