Sento in Tokyo: a first-timer's guide to the public bath

Tucked between apartment blocks all over Tokyo are neighbourhood bathhouses called sento: big hot baths, a painted mountain on the wall, and locals of every age unwinding after work. Going for the first time can feel intimidating, mostly because you don't know the routine. Once you do, it becomes one of the most relaxing, most Tokyo things you can do, often for less than the price of a coffee and a cake. Here's exactly how it works.

Sento, onsen, super sento: what's the difference?

Sento

A neighbourhood public bath, traditionally for people whose homes had no bath. Usually heated tap water, sometimes natural spring water. Small, local, and the adult price is set across Tokyo, so it's the same at most sento.

Onsen

A bath that uses natural hot spring water. Famous onsen towns are outside the city, but some Tokyo bathhouses have spring water too, including the dark brown "black water" found in parts of the city.

Super sento

Bigger leisure complexes with many baths, saunas, restaurants and relaxation rooms. Easy for beginners, but they cost more and feel less local.

Sauna culture

Many sento now have a sauna and a cold plunge bath, sometimes for a small extra fee. Sauna, cold bath, rest, repeat is a whole hobby in Japan.

The whole routine on one page. Step 4 is the one that matters most.

Your first visit, step by step

  1. Shoes off at the entrance. Put them in a small shoe locker and keep the key, often a wooden one.
  2. Pay and choose your side. Pay at the front desk or the ticket machine. The bath is split by gender: look for the curtains marked 男 (men) and 女 (women), often in blue and red.
  3. Undress completely. Clothes go in a locker or basket in the changing room. No swimsuits. Take your small towel and your toiletries in with you.
  4. Wash before you soak. Sit on a stool at one of the shower stations and wash from head to toe. Rinse off every bit of soap. This is the one rule everyone cares about.
  5. Ease into the bath. Some baths are very hot, so go in slowly. Keep your towel out of the water (folding it on your head is classic) and tie up long hair.
  6. Dry off before you leave the bath area. Wipe yourself down with your small towel so you don't drip all over the changing room floor.
  7. Finish with a cold drink. A glass bottle of milk, coffee milk or fruit milk after the bath is a beloved tradition.

Good to know

Why a sento is the perfect solo plan (and a great one with a friend)

A sento is one of the best things to do alone in Tokyo: nobody expects conversation, and you walk out feeling like a new person. It's also a lovely plan with a friend, especially on a cold or grey day; pair it with our rainy day plans. Because the baths are split by gender, a sento visit is a natural plan with a friend of the same gender: soak separately, then meet in the lobby for a cold milk and a chat. If you're visiting Japan, add one to your solo trip list; it's the kind of everyday Tokyo that guidebooks skip.

Questions people ask

What is a sento in Japan?

A sento is a neighbourhood public bathhouse. You wash at a shower station, then soak in large shared hot baths. Baths are separated by gender and you bathe without a swimsuit.

What is the difference between a sento and an onsen?

An onsen uses natural hot spring water, while a sento is a public bath that usually uses heated tap water. Some sento in Tokyo do use natural spring water, so the line can blur.

Can I go to a sento with tattoos in Tokyo?

Often, yes. Many neighbourhood sento are relaxed about tattoos, but some bigger facilities still restrict them. Check the sign at the entrance or ask the staff before paying.

What should I bring to a sento?

A small towel, a big towel, soap and shampoo, a hair tie if you have long hair, and some cash. If you forget something, most sento sell or rent towels and basics at the front desk.

Do I need to be naked at a sento?

Yes. Swimsuits are not worn in Japanese public baths. Everyone washes first, and the baths are separated by gender, so it quickly feels normal.
