Five Neighborhood Sento in Matsuyama: Which One Should You Visit?
Compare five Matsuyama sento by natural spring water, sauna, rental supplies and opening days; listings disagree on Suishoyu’s schedule.
If you want a simple local bath rather than a full-scale spa, Matsuyama still has several working sento. The city’s 2026 list includes Kotobuki-yu, Shimizu-yu, Hakusenyu, Shinkai Onsen and Suishoyu. The first thing to know is that the word “onsen” in a bathhouse’s name does not, by itself, prove it uses natural hot-spring water. Kotobuki-yu is the exception here: its operator and Ehime’s tourism bureau both identify a spring source.
The details below were checked against city, prefectural and bathhouse-association listings on September 7, 2026. Prices and schedules can change, and two listings conflict for some facilities. Call before travelling if your visit depends on a particular day or opening time.
Compare the five bathhouses
| Bathhouse | Adult price | Listed hours | What stands out | Check before you go |
|---|---|---|---|---|
| Kotobuki-yu | ¥510 | 7:30 a.m.–11 p.m. | Natural spring water from Oku-Dogo, dry sauna, steam sauna and a well-water cold bath | Irregular closing days; no free shampoo or soap in the bathing area |
| Shimizu-yu | Confirm at the venue; prefectural cap is ¥500 | 2:30–9:30 p.m. | Straightforward afternoon sento, with five parking spaces | Closed on the first and third fixed closing days listed by the association |
| Hakusenyu | Confirm at the venue; prefectural cap is ¥500 | 4–9 p.m. | A neighborhood bath on Matsuyama’s west side | City and association listings differ on closing days |
| Shinkai Onsen | Confirm at the venue; prefectural cap is ¥500 | 2–10:30 p.m. | Latest closing time and the broadest published list of towels and toiletries | Closed on the 10th and 25th of each month |
| Suishoyu | Confirm at the venue; prefectural cap is ¥500 | Matsuyama City lists 3–9 p.m. | Sauna and a notably cold plunge bath | Opening days conflict across current listings; call first |
Ehime’s ¥500 figure is a regulated ceiling for ordinary public baths from April 1, 2026. It is not a promise that every bath charges exactly that amount; Kotobuki-yu currently publishes ¥510.
Neither the prefectural fee notice nor the bathhouse listings explain the ¥10 difference, so there is no basis to label it a tax or sauna surcharge. Budget for the listed price and ask the bathhouse if you need a precise total.
Kotobuki-yu: the one with a confirmed natural spring
Kotobuki-yu draws water from Oku-Dogo Onsen. Its published analysis describes an alkaline simple hot spring at 32.5°C and pH 9.1. The spring water is also used in the washing-area taps and the steam sauna, not only in the main bath. A separate dry sauna and a cold bath filled with well water round out the facilities.
At ¥510 for adults, it sits close to the general-bath price range while offering a documented natural source. Soap and shampoo are not complimentary in the bathing area, so bring your own or ask at the counter. There are five parking spaces; the operator says it will contribute ¥100 toward nearby coin parking if its own lot is full.
The city lists hours of 7:30 a.m.–11 p.m. and says the bathhouse closes irregularly. The association listing still shows an earlier start and different closing-day information. If you are hoping to arrive around 6 a.m., phone first rather than trusting a search snippet.
Shinkai Onsen: best when you are going after dinner
Shinkai Onsen is listed from 2 p.m. to 10:30 p.m., later than the other neighborhood baths here. It closes on the 10th and 25th of each month. For visitors who did not pack bath supplies, the association page is unusually specific: it lists towels, soap, shampoo, conditioner, body wash, razors, toothbrushes, nylon washcloths, scrubbing towels, and both towel rental and bath-towel rental.
That does not make it a spa. It is a local bathhouse with eight parking spaces, rather than a place to spend half a day in a lounge. But if dinner runs late and you want a quick wash before returning to your hotel, its hours and supply options are practical.
Suishoyu: sauna fans should verify the schedule first
Suishoyu’s association listing calls out its sauna and very cold plunge bath. It also lists five parking spaces and basic bathing supplies for sale. If that simple sauna-and-cold-water routine is what you are after, it may be more appealing than a bathhouse with a longer list of tubs.
The schedule is the problem. Matsuyama City’s 2026 page lists 3–9 p.m. and says it closes Mondays, Tuesdays and Thursdays. The bathhouse association lists 2–9 p.m. and says Wednesday and Saturday are closing days. Since those differences could send you to a locked door, call 089-941-3616 before building an evening around Suishoyu.
Shimizu-yu and Hakusenyu: choose by where you are staying
Shimizu-yu is listed by both the city and the association as open from 2:30 to 9:30 p.m., with the same first-and-third closing-day pattern. The association lists five parking spaces and sales of towels, soap, shampoo, conditioner and scrubbing supplies. It is an easy neighborhood option if you are staying nearby; its published material does not establish a natural hot-spring source.
Hakusenyu sits in the Minamisaida area and is listed from 4 to 9 p.m. by both sources. The city page calls its closing days irregular, while the association lists the 6th, 16th and 26th of each month. There is less current facility information than for the other four baths, so do not assume it has a sauna, towel rental or natural spring unless you confirm directly. It makes most sense if you are already on the west side of Matsuyama.
Which one fits your visit?
- Natural spring on a neighborhood-bath budget: Kotobuki-yu. It is the only one of these five with a clearly documented spring source, and it also has two saunas.
- A bath after a late dinner: Shinkai Onsen, listed until 10:30 p.m. Check the calendar dates it closes.
- Sauna and a cold plunge: Kotobuki-yu or Suishoyu. Suishoyu’s opening-day discrepancy makes a phone call essential.
- An uncomplicated afternoon stop: Shimizu-yu has the most consistent schedule across the two listings.
- A bath near your accommodation on the west side: Hakusenyu, provided you confirm it is open that day.
