Winter Wellness in Tokyo: Sento, Yuzu Baths & Warm Japanese Rituals for Cold Days

Winter wellness in Tokyo means doing what locals have done for centuries on cold days: a long soak at the neighbourhood sento, a yuzu citrus bath on the winter solstice (Tuesday, December 22, 2026), an evening under the kotatsu, and bowls of oden, nabe or sweet amazake. These rituals are cheap, easy for visitors to join, and a lovely way to see everyday Tokyo. This guide explains how they work, with sento etiquette and a few bathhouses near Kinshicho and Kameido.

What is a sento, and why go in winter?

A sento (銭湯) is a neighbourhood public bathhouse. Unlike an onsen, the water is usually ordinary heated tap water (some sento use natural spring water), and the price is set by the Tokyo Metropolitan Government. From August 1, 2026, the adult price in Tokyo is ¥600, with lower fees for children. Many people still visit every day, especially older residents, and in winter a hot bath before bed is a real comfort when Japanese homes can feel cold.

What you will typically find inside:

Separate men’s and women’s sides, marked 男 (men) and 女 (women), often on blue and red noren curtains
Rows of washing stations with stools, showers and shampoo (bring your own in older sento)
Two or three baths at different temperatures, often including a jet bath, an “electric bath” and a herbal bath (yakuto) that changes regularly
Many sento have a sauna for an extra fee, and a classic Mount Fuji mural on the wall

The Tokyo Sento Association has an English guide and a map of sento across the city.

Sento etiquette for first-timers

Sento etiquette is simple, and staff and regulars are used to visitors:

Pay at the front desk (or a ticket machine). Towels, soap and shampoo are usually sold or rented if you did not bring them.
Shoes off at the entrance and leave them in a shoe locker.
Undress completely in the changing room and leave everything in a locker. Swimsuits are not worn.
Wash thoroughly first at a washing station, sitting on the stool, and rinse off all soap before entering any bath.
Keep your small towel out of the water. Locals fold it on their head or leave it on the side.
Tie up long hair so it does not touch the water.
No phones or cameras in the bathing area, and keep your voice down.
Dry off before returning to the changing room so you do not drip on the floor.

What about tattoos?

Policies vary. Many neighbourhood sento in Tokyo are relaxed about tattoos, because they are local public baths rather than resort facilities. Larger “super sento”, spa complexes and many hot-spring resorts are much more likely to refuse entry or ask you to cover tattoos. If in doubt, check the sento’s website or social media, look for a sign at the entrance, or simply ask at the desk before you pay.

Yuzu-yu: the winter solstice citrus bath

On the winter solstice (toji), the shortest day of the year, Japanese families and sento float whole yuzu fruits in the bath. In 2026 the solstice falls on Tuesday, December 22, according to the National Astronomical Observatory of Japan.

Where the custom comes from: it is often said that the custom began at Edo-period public baths as a special themed bath, and the old saying goes that a yuzu bath on the solstice keeps colds away. Treat that as folklore: it is about tradition and seasonal pleasure, not medicine.
What it is like: the bath smells fresh and citrusy, and the floating fruit is quite a sight. Some sento put the yuzu in mesh bags; others let them float freely.
Where to try it: many Tokyo sento offer a yuzu bath on or around December 22. Look for posters at the entrance in mid-December, or check the sento’s social media.
Solstice food: people also eat kabocha (Japanese pumpkin) on the solstice, often simmered sweetly with azuki beans.

If your skin is sensitive, a short soak is enough; some people find yuzu peel irritating.

Kotatsu and other ways Japan keeps warm

Many Japanese homes have little or no central heating, so warmth is local and personal:

Kotatsu. A low table with a heater underneath and a quilt draped over it. The family sits with their legs under the quilt to eat, watch TV and, inevitably, doze off. Some cafes, ryokan and traditional restaurants have kotatsu seating in winter, so ask when booking.
Kairo. Disposable heat packs sold at every convenience store and drugstore, in stick-on and pocket versions. Do not stick them directly onto skin or sleep with them in place; they can cause low-temperature burns.
Yutanpo. A hot-water bottle, still popular with older people.

Warming winter foods to try in Tokyo

Food	What it is	Where to find it
Oden	Daikon, eggs, fish cakes and konnyaku simmered in a light dashi broth	Convenience store counters in the cold months, oden shops, izakaya
Nabe	Hot pot cooked at the table; chanko nabe is the sumo version	Restaurants everywhere; Ryogoku for chanko
Amazake	A sweet, thick rice drink; the koji version is alcohol-free	Shrines at New Year, cafes, vending machines
Yaki-imo	Roasted sweet potato	Supermarkets, street trucks, convenience stores
Toshikoshi soba	Buckwheat noodles eaten on New Year’s Eve	Soba shops and homes on December 31

Note that some amazake is made from sake lees (sake-kasu) and contains a small amount of alcohol. If you avoid alcohol or are serving children, ask which kind it is.

Bath safety in cold weather

Japan’s Consumer Affairs Agency issues a warning every winter about bathing accidents, which are most common among older people from November to March. Its advice applies to travellers too: warm the changing area before you undress, keep the water at about 41°C or lower, limit soaks to around 10 minutes, and avoid bathing right after a big meal, after drinking alcohol or after taking medicine that makes you drowsy. See the Consumer Affairs Agency guidance (Japanese). If you have heart problems or high blood pressure, ask your doctor before using very hot baths or saunas, and get out and sit down if you feel dizzy.

Acupuncture and moxibustion in Japanese seasonal self-care

Acupuncture (hari) and moxibustion (kyu) have been part of Japanese everyday health culture for centuries. In Japan they are regulated professions with separate national licences for acupuncture and for moxibustion. In moxibustion, small amounts of dried mugwort (moxa) are burned on or near the skin to produce gentle warmth. It has a long association with travel and the cold seasons: in the opening of The Narrow Road to the Deep North (1689), the poet Matsuo Basho mentions applying moxa to the “sanri” point below his knee as he prepares for a long walking journey.

What the evidence says, in short:

The US National Center for Complementary and Integrative Health (NCCIH) says acupuncture may help some pain conditions, such as back and neck pain, and is generally safe when done by a qualified practitioner using sterile, single-use needles. Evidence for many other uses is limited.
For moxibustion, research is less developed. An overview of systematic reviews found the evidence inconclusive for most conditions, based on studies with a high risk of bias, and a review of case reports lists burns as the most commonly reported adverse event. That is why it should only be done by a licensed practitioner.

At Fuji Wellness in Edogawa City, some winter visitors book a session simply to experience this part of Japanese tradition, or because many hours of walking in the cold leave their shoulders and back feeling stiff. Consultations are in English, Vietnamese or Japanese with a practitioner who holds both national licences (鍼師 and 灸師), by appointment only. The clinic is open Monday to Thursday 9:00–12:00 and 14:00–17:00 (so the December 22 solstice, a Tuesday, is a normal day), and Saturday, Sunday and public holidays 8:00–12:00; it is closed on Fridays.

Can I go to a sento with tattoos?

When is the yuzu bath (yuzu-yu) in 2026?

Yuzu baths are traditionally held on the winter solstice, which in 2026 falls on Tuesday, December 22. Many Tokyo sento offer yuzu baths on or around that day; look for posters at the entrance or check the sento’s social media.

What should I bring to a sento?

A small towel, a larger towel for drying, soap and shampoo (if the sento does not provide them), and some cash or an IC card for payment. Everything can usually be bought or rented at the front desk.

Is moxibustion safe?

When performed by a licensed practitioner, moxibustion is generally considered low risk, but burns are the most commonly reported adverse event in published case reports. Research on its effectiveness is limited, so treat it as a traditional practice rather than a proven treatment, and avoid trying it at home without guidance.
