Tokyo had 417 public bathhouses left on 31 December 2025, against 2,687 at the 1968 peak, according to the Tokyo Metropolitan Government's own series (page updated 21 July 2026). The surprise sits one row further down the same table: the survivors are busier than they were fifteen years ago, averaging 180 bathers per bathhouse per day in 2025 against 120 in 2011.

That combination is what makes a 銭湯 (sento) worth your evening rather than just your sympathy. It is one of the few genuinely cheap fixed-price things left in central Tokyo: the fee is not set by the owner, it is capped by the Governor, and from 1 August 2026 the adult ceiling is JPY 600.

This guide covers ordinary public bathhouses in Tokyo Metropolis. It does not cover onsen resorts, super sento, health lands, or hotel spas, which are priced and regulated differently.

How many sento remain?

Tokyo's public bathhouse count has been published annually by the Tokyo Metropolitan Government, measured at 31 December each year, and it has fallen in every one of the last fourteen years. The table below is that series as printed on the "東京の公衆浴場はどうなっているの?" page (Tokyo Metropolitan Government, page updated 21 July 2026, checked 7 September 2026). The metropolitan total splits into the 23 special wards and the Tama-area cities.

Year (31 Dec) Tokyo total 23 wards Cities
2025 417 382 35
2024 430 393 37
2023 444 406 38
2022 462 420 42
2021 480 436 44
2020 499 453 46
2019 520 473 47
2018 545 492 53
2017 562 508 54
2016 602 548 54
2015 628 574 54
2014 669 612 57
2013 706 645 61
2012 741 675 66
2011 766 698 68

Going further back requires a different document, and the longer view is steeper than the recent one. These are the milestones, each with the source that publishes it and what that source is counting.

Year Count Source and what it counts
1937 about 2,900 Tokyo Sento Association Q&A, from its own membership roster
1945 about 400 Tokyo Sento Association Q&A, after the Tokyo air raids
1968 2,687 Peak; Tokyo Sento Association series and Metropolitan Government advisory-council paper
1998 1,390 Metropolitan Government advisory-council paper, index 51.7 against 1968
2008 879 Metropolitan Government advisory-council paper, index 32.7 against 1968
2025 417 Metropolitan Government current-status page, 31 December 2025

The advisory-council paper (東京都公衆浴場対策協議会 資料, checked 7 September 2026) sets 1968 as index 100 and puts 2023 at 16.5. Roughly five out of every six Tokyo bathhouses that existed in 1968 are gone.

The user figures move differently, and this is the part that gets left out of most retellings. Total annual visits in Tokyo fell from 28,519,000 in 2011 to 21,185,000 in 2025, but because the number of bathhouses fell faster, the average number of bathers per bathhouse per day rose from 120 in 2011 to 180 in 2025. In 1968 that same figure was 530, so the recent rise is a partial recovery, not a return.

Which count should you trust?

Two organisations publish Tokyo bathhouse counts and they do not always agree, so it matters which one a claim came from. The Tokyo Metropolitan Government publishes the 公衆浴場 series above. The Tokyo Sento Association (東京都公衆浴場業生活衛生同業組合), the governor-authorised trade association founded on 2 December 1957, publishes its own year-by-year table of 銭湯 numbers on 1010.or.jp (checked 7 September 2026).

For most years the two match exactly. For a few they do not. The association's table gives 699 for 2014 where the Metropolitan Government gives 669; 544 for 2018 against the Government's 545; and 481 for 2021 against 480. Neither page explains the gap, and this guide does not reconcile them, because averaging two series with different collection routes would produce a number that no authority actually stands behind.

There is a third, larger number that is frequently confused with these. The Ministry of Health, Labour and Welfare's 公衆浴場業概要 reports 23,673 licensed public bath facilities nationwide as of 31 March 2024, of which 2,847 were 一般公衆浴場 — the ordinary neighbourhood bathhouse category (MHLW, checked 7 September 2026). The gap between 23,673 and 2,847 is the point: under the Public Bath Houses Act, saunas, health lands, sports facilities and private-room bath businesses are all "public baths" too. The Statistics Bureau's own FAQ lists those categories explicitly (Statistics Bureau, checked 7 September 2026). A headline that says "Japan has 23,000 public baths" and a headline that says "only 2,847 remain" can both be sourced to the same ministry table.

Why did they close?

The decline has four documented drivers, and all four appear in government text rather than in commentary. The Ministry of Health, Labour and Welfare's own summary attributes the fall to worsening finances caused by falling bather numbers as home baths spread, closure due to lack of a successor, and conversion of well-located sites to other businesses. The same page cites a 95.5 per cent household bath-ownership rate from the 2008 Housing and Land Survey, and notes that ordinary public bathhouses were 87 per cent of the bath industry around 1970 but 12.0 per cent in fiscal 2023.

Fuel is the second pressure, and it is measurable. As of 1 September 2024, 72.5 per cent of Tokyo's bathhouses burned city gas exclusively, 14.8 per cent used a mix including miscellaneous fuel, heavy oil or waste oil, 2.9 per cent burned waste oil alone, and only 2.2 per cent ran on heat pumps alone (Tokyo Metropolitan Government, その他の情報 PDF, checked 7 September 2026). A business that heats several tonnes of water every day on city gas, at a price it is legally forbidden to raise on its own, is exposed to energy prices in a way almost no other retail business is. Tokyo has run emergency fuel-cost subsidies for bathhouses for exactly that reason.

Succession and building age are the third and fourth. The same metropolitan document tabulates stated closure reasons from 2010 onward, with ageing facilities, no successor and operator age or illness recurring every year. Land value is the quiet one: a bathhouse occupies a large, low-rise plot, often near a station, in a city where that plot is worth more as apartments. The ministry names this directly as "conversion to other business using its advantageous location".

What the closure table also shows is that the bleeding has slowed. Tokyo recorded 39 closures in 2010 and 41 in 2015, but 18 in 2022, 19 in 2023, and 13 in the year to 1 September 2024 — a partial year, because that is the document's cut-off date. Fewer bathhouses remain to close, but the annual rate has come down alongside the rising per-bathhouse attendance.

What does a sento cost?

The price of an ordinary Tokyo bathhouse is a legal ceiling, not a market price, and the ceiling changed on 1 August 2026. Under the Price Control Ordinance and a 1957 ministerial ordinance, each prefectural governor designates the maximum bathing fee; in Tokyo the Public Bath Countermeasures Council calculates costs from operators' accounts and the Governor announces the figure (Tokyo Metropolitan Government, 統制額について, checked 7 September 2026).

The table below compares what you pay against what that payment actually buys, so you can see where the fixed price stops.

Item Price Included in the regulated fee?
Adult, 12 and over JPY 600 Yes, this is the capped fee
Child 6-11 JPY 200 Yes, unchanged since 2022
Child under 6 JPY 100 Yes, unchanged since 2022
Soap, shampoo, towel Varies No, sold separately on site
Sauna, where present Varies No, separate charge at some bathhouses

Those adult, child and infant figures take effect on 1 August 2026 and are published identically by the Metropolitan Government and by the Tokyo Sento Association. The adult ceiling rose by JPY 50 from the JPY 550 that applied from 1 August 2024; the two children's rates were held.

The longer price history is short enough to read in one glance, and it is the clearest single illustration of how slowly this price moves: JPY 460 from 1 July 2014, JPY 470 from 1 October 2019, JPY 480 from 1 August 2021, JPY 500 from 15 July 2022, JPY 520 from 1 July 2023, JPY 550 from 1 August 2024, JPY 600 from 1 August 2026.

What must you bring?

You can walk into a Tokyo sento carrying nothing, and the association says so in plain terms on its own how-to page: bring your usual towel, soap and shampoo in a small bag if you have them, but it is fine to bring nothing, because most bathhouses sell mini soap, mini shampoo, mini conditioner and towels, and some sell a complete bath set (Tokyo Sento Association, 銭湯の入り方, checked 7 September 2026).

Two practical consequences follow. First, budget above the JPY 600. If you arrive empty-handed, the toiletries and towel are a real second transaction, and their price is not regulated. Second, if you have a sauna in mind, ask at the desk before you pay, because the association states plainly that some bathhouses collect a separate sauna fee and others do not.

A few smaller rules are worth knowing before you undress rather than after. Tokyo stopped charging a separate hair-washing fee on 1 May 1970, so washing your hair costs nothing extra even though the national ordinance still allows that fee category to exist. Since 1 January 2022, following a Tokyo ordinance revision that lowered the mixed-bathing age limit from 10 to 7, a child aged 7 or over may not enter the opposite-sex bath. And underwear comes off in the changing room, not in the bathing hall — the association's guide flags this specifically as something visitors have started getting wrong.

What is not true?

Several widely repeated claims about Tokyo bathhouses do not survive contact with the official pages, and it is worth stating the absences precisely. There is no single authoritative count: the Metropolitan Government series and the Tokyo Sento Association series disagree in at least three of the last twelve years, and neither publishes a reconciliation. There is no national count of "sento" as such either, only the ministry's 一般公衆浴場 category inside a much larger licensed-facility total.

There is no blanket rule on tattoos. The Ministry of Health, Labour and Welfare's public bathhouse page links to Japan Tourism Agency guidance on bathing by tattooed foreign travellers, framed as points to note and examples of responses circulated to industry, not as a permission or a prohibition (MHLW, checked 7 September 2026). No official page consulted here states that Tokyo sento generally admit tattooed bathers, and none states that they generally refuse. The decision sits with the individual bathhouse, which means the only reliable method is to ask at the desk before paying, and to accept the answer you get. The same page also carries requests for understanding toward bathers wearing bathing garments and toward ostomates, which are appeals to operators and other bathers rather than enforceable rights.

There is also no published, verifiable list of which bathhouses rent rather than sell towels, what a sauna surcharge costs, or which take cards. The association describes toiletries and towels as sold, and the sauna charge as varying by bathhouse; on payment, the Metropolitan Government was still running a fiscal 2026 subsidy to help bathhouses introduce cashless payment (Tokyo Metropolitan Government, checked 7 September 2026), which is a clear signal that card acceptance is incomplete. Carry coins.

How do you actually go?

Going to a sento is a fifteen-minute decision and a ninety-minute evening, and the order of operations is fixed enough to write down. Work through it in sequence rather than improvising at the shoe lockers.

  1. Find one near where you are already sleeping or eating. The association maintains the official Tokyo sento map at 1010.or.jp; density is highest in the 23 wards, which held 382 of the 417 bathhouses at the end of 2025.
  2. Confirm that bathhouse's hours and its sauna and tattoo position by contacting it directly. Neither is centrally published.
  3. Bring JPY 600 in coins plus a margin for toiletries, or buy the ten-ticket book if you expect several visits.
  4. Take off your shoes at the entrance and put them in the shoe box, then keep the wooden tag or key. The association warns that boots may not fit some shoe boxes.
  5. Pay at the 番台 raised desk or the フロント counter, or at a ticket vending machine where one is installed, and ask about the sauna at this moment if you want it.
  6. Undress completely in the changing room, lock your locker, and carry the key on your wrist. Where a bathhouse still uses open baskets rather than lockers, hand valuables to the attendant.
  7. In the bathing hall, rinse first with a bowl of hot water from the tap before entering the tub, then wash, then soak. Water runs hot, usually around 42 degrees Celsius in a tub over 50 cm deep.
  8. Dry off before you step back into the changing room, and drink something before and after. The association makes the point about hydration twice on the same page.

The number that should stay with you is not 417. It is 180 — the average bathers per bathhouse per day in 2025, up from 120 in 2011. The closures are real and documented year by year, but the remaining bathhouses are not empty rooms waiting to be photographed before they vanish. They are working neighbourhood infrastructure at a price the city fixes, and the most useful thing a visitor can do with the statistics above is spend JPY 600 on one.
