TOKYO / SUMIDA & TAITO / SENTO

Most guides to “tattoo-friendly onsen in Tokyo” send you to a hotel spa in Shinjuku or a resort bath by the bay. That is the wrong answer to the wrong question. The right question is: where can a person with tattoos take a proper Japanese bath, in a neighborhood, for the price of a coffee? The answer is a sento, the public bathhouse, and the east side of Tokyo has the best ones in the city, several of which have written “tattoos welcome” on their own websites.

Since August 1, 2026, the fixed adult price at every sento in Tokyo is ¥600. Children are ¥200. Here is how it works, and three baths east of the river that will not look twice at your arms.

Sento, onsen, and why the tattoo rule is different

An onsen is a bath fed by a natural hot spring; a sento is a bath fed by a boiler. The bathing is the same. The difference that matters to you is legal and cultural: sento are regulated as public hygiene facilities with a price fixed by the prefecture, and they grew up serving working neighborhoods where nobody had a bathtub at home. A tattoo in a sento in Sumida is a much smaller event than a tattoo in a resort onsen in Hakone. Many sento simply never had a rule. The ones below have gone further and said so in public.

Three baths that say it on their own website

Koganeyu (黄金湯), Kinshicho, Sumida

A 1930s bathhouse rebuilt in 2020 by a couple who also run two other baths and a brewery, with a DJ booth and a beer tap at the front desk, a bathing hall behind, and one of the more serious saunas in east Tokyo behind that. Its FAQ answers the tattoo question in three words: you can bathe. Six minutes from the north exit of Kinshicho Station.

• Hours: 6:00–9:00 and 11:00–24:30 every day. Closed the 2nd and 4th Monday. Wednesday is the swap day (men’s and women’s sides switch).
• Price: ¥600 for 90 minutes. Sauna extra: women ¥350–400, men ¥550–600 for two hours (walk-in or web reservation; it fills on weekends). Towel set ¥200. Shampoo, soap and dryers free.
• Pay: cash or PayPay for the bath; cards accepted at the bar.
• Also: dormitory rooms upstairs if you want to sleep at a bathhouse, and their own craft beer after.

Daikokuyu (大黒湯), Oshiage, Sumida

Koganeyu’s older sister, founded 1949, six minutes from Oshiage Station and ten from the base of Skytree. A real hot-spring source (the water is mildly alkaline), a large rooftop outdoor bath from which you can see the tower, a painted Fuji on the wall, and the first sento in the 23 wards to run all night. If you land late and want a bath before a bed, this is the one.

• Hours: weekdays 15:00 to 10:00 the next morning; Saturday from 14:00; Sunday and holidays from 13:00. Closed Tuesday (open if Tuesday is a holiday, then closed Wednesday).
• Price: ¥600; sauna and late-night surcharges apply, check the board.
• Tattoos: same owners, same policy as Koganeyu; widely and repeatedly confirmed by visitors with visible work.

Kotobuki-yu (寿湯), Higashi-Ueno, Taito

The old-school option. A temple-roofed miya-zukuri bathhouse two minutes from Inaricho Station on the Ginza Line, one stop from Ueno, with what it claims is the largest outdoor bath of any sento in Tokyo on the men’s side, an electric bath (a mild current through the water; try it once), and a different themed bath almost every day of the month. No design studio touched it. Tattooed regulars have been bathing here for years and the staff do not react.

• Where: 5-4-17 Higashi-Ueno, Taito. Inaricho Station, 2 minutes.
• Price: ¥600. Check the monthly holiday calendar on the door or the website before you go; the rest day moves.

How to not embarrass yourself (it is easy)

1. Shoes go in the locker at the entrance. Take the wooden key.
2. Pay at the front desk (¥600, cash is safest). Say “sauna” if you want it. Buy or bring a small towel; you carry it in, you do not put it in the bath.
3. Undress completely in the changing room. Everything in the locker. There is no swimwear in a sento, ever.
4. Sit at a tap, wash your whole body with soap, rinse. Then get in. This is the one rule everyone will notice if you skip it.
5. Hair up or out of the water. Voices low. No phones past the changing room, no photos anywhere inside.
6. Wring your towel out and pat yourself down before walking back into the changing room, so you do not drip on the mats.
7. Drink something cold on the way out. That is the entire point.

If you want someone to walk you in

You do not need a tour for any of the above. But the first time in a sento, with the shoe locker and the ticket machine and the etiquette, is the one that stops people going at all, and a guided first visit fixes that permanently. Two that are honest about being for tattooed guests:

• Tattoo-Friendly Traditional Bathhouse & Ramen Tour: two to three hours in the old downtown, a local sento with a guide who explains the room, then ramen. Around ¥9,000, entry included. Small and new, which is why it is cheap.
• Soak, Steam and Eat: Tokyo Onsen Adventure: the longer version, four to five hours with sauna and a meal, around ¥11,200. Confirm the tattoo policy of the specific bath with the operator when you book; they choose the venue.

After one guided visit, you will never need another. Go to Koganeyu on your own the next night.

Make it an evening

Koganeyu and Daikokuyu are fifteen minutes’ walk apart, either side of the Edo Kiriko museum in Kinshicho. Cut a glass in the afternoon, bathe at six, drink the house beer at Koganeyu, and if you are still awake, Daikokuyu’s rooftop bath is open until ten the next morning. That is a Sumida day nobody sells as a package, and it costs about ¥6,000 including the glass.

Tattoo-friendly baths near Asakusa

Two more, for people staying in Asakusa who do not want to cross the river. Both are listed as tattoo-friendly on the Japanese bath directories; neither prints a policy on its own site, so if you are heavily inked, a polite question at the counter costs nothing.

• Hinode-yu, Moto-Asakusa: a natural hot-spring sento on the ground floor of an apartment block, three minutes from Inaricho Station on the Ginza line and fifteen on foot from Senso-ji. Ancient-cypress tub, steam sauna, a ¥100 carbonated shower, and a small café at the front desk. 14:00 to 22:40, closed Wednesdays. ¥600.
• Mikokuyu, Ishihara (Sumida): the best bath within walking distance of Asakusa, eight minutes over the Kuramae bridge. Five floors of black natural hot spring with a rooftop open-air bath that looks straight at the Skytree, a different medicinal bath each day, and a reputation for being easy for foreigners and for tattoos. 15:30 to 2:00, closed Mondays (Tuesday if Monday is a holiday). ¥600.

Private baths, and bathing as a couple

Every sento on this page is separated by sex at the changing-room door; there is no mixed bathing and no swimwear. If you want to bathe together, you need a private bath, and on the east side the honest answer is that there are very few. Mikokuyu has one, a “welfare-type family bath” with rails and a lift, ¥1,500 per person for 90 minutes, reservation required, and it is meant for people who need help bathing and their carers; do not book it as a date. Daikokuyu’s rooftop has a small open-air tub for one that is not bookable. Beyond that, a private bath in this part of Tokyo means a hotel room with one, or the private sauna rooms that have opened around Sumida and Ginza at ¥5,000 to ¥30,000 an hour, which allow tattoos because nobody else is there. For a couple with tattoos, the practical plan is: go to the same sento at the same time, meet in the lobby afterwards with a bottle of milk, and walk to Mikokuyu’s rooftop on a different night for the view. If you would rather someone else had the conversation at the counter, there is now a guided tattoo-friendly bathhouse and ramen evening that meets at Kinshicho and ends at Daikokuyu, listed in the ramen classes and tours comparison — about ¥9,000 for what you can do yourself for ¥1,500.

Quick answers

Further north, Takara-yu in Kita-Senju has the best bathhouse garden in Tokyo; it does not publish a tattoo policy, so it is not on this list, but it is worth knowing about.

Practical notes

• Price: ¥600 adults, ¥200 children (6–11), ¥100 under 6, fixed across Tokyo since August 1, 2026. Sauna is extra.
• Bring: a small towel (or buy one for ¥200–300), coins, nothing else. Soap and shampoo are usually provided at the baths above; at older sento, bring your own.
• Tattoos: Koganeyu states it in writing; Daikokuyu is the same owners; Kotobuki-yu is long established as tattoo-tolerant. Elsewhere, look for a sign at the door; no sign usually means no rule.
• Do not: wear swimwear, get in without washing, put your towel in the water, take a phone into the bathing hall, or bathe drunk (Koganeyu will turn you away).

LOCAL SIDE JAPAN checked prices, hours and tattoo policies against the bathhouses’ own websites (Koganeyu, Daikokuyu, Kotobuki-yu) and the Tokyo Metropolitan Government’s August 2026 price notice on September 14, 2026. Rest days and sauna surcharges change monthly; check the door.
