Shirahama Public Baths: Saki-no-Yu, Muro-no-Yu, Shirarayu or Matsunoyu?
Choose among four Shirahama public baths: Saki-no-Yu by the sea, Muro-no-Yu’s two springs, Shirarayu by the beach and Matsunoyu near the bus centre.
These are small public baths, not half-day spa complexes. Bring time to change and rinse, but do not expect a lounge, restaurant or a long list of pools. If you want a sauna, meals and a longer stay, look for one of Shirahama’s larger day-use facilities instead.
The four baths at a glance
| Bath | Adult admission | Public opening hours | Best reason to choose it |
|---|---|---|---|
| Saki-no-Yu | ¥500 (age 3+) | Seasonal: 8 a.m.–6 p.m. in April–June and September; 8 a.m.–5 p.m. October–March; 7 a.m.–7 p.m. July–August | Open-air bathing beside the Pacific |
| Muro-no-Yu | ¥420 | 9–11 a.m. and 2–9:30 p.m.; last entry 9 p.m. | Two different hot-spring sources in one bathhouse |
| Shirarayu | ¥420 | 9–11 a.m. and 2–9:30 p.m.; last entry 9 p.m. | A soak after Shirarahama Beach |
| Matsunoyu | ¥400 | 1–9 p.m. | A low-cost stop near Shirahama Bus Center |
Children’s admission is lower at the municipal baths. Bring cash and a small towel; towels and basic washing items can be bought at some facilities, but not all baths stock the same supplies.
Saki-no-Yu: sea views, with a weather-dependent catch
Saki-no-Yu is an exposed open-air bath where waves and sea spray are part of the setting. You cannot use shampoo, conditioner or soap because the bath water drains toward the sea. Its hours change by season, and entry closes 30 minutes before the posted closing time.
As of September 28, 2026, Shirahama Town’s notice said the sea-facing bath was closed after a typhoon brought high-wave risk. The notice does not say the entire facility is closed. Check for a reopening notice before making this your main stop; rough seas can also lead to temporary closures after normal operations resume.
From Shirahama Station, the town lists a bus to Yuzaki, followed by about a five-minute walk. The Saki-no-Yu parking lot has 15 spaces, so the bus is the lower-stress choice on a busy beach day.
Muro-no-Yu: the useful choice if you want to compare springs
Muro-no-Yu draws from two sources: Mabu-yu and Miyuki-yu, the latter also used at Saki-no-Yu. This is the one to choose if the water itself is the reason for your stop. Tourists can enter from 9 to 11 a.m. or 2 to 9:30 p.m.; the 7–9 a.m. session is reserved for Shirahama residents. It closes on Tuesdays.
The bus stop is Yuzaki, followed by a short walk. Its two pools do not turn the visit into a complex circuit; most people can keep this to one soak before moving on to the next part of town.
Shirarayu is easiest to pair with the beach
Shirarayu is across from Shirarahama Beach, with the bathing area upstairs and a view over the sand. It is a natural end to a beach visit, but it is not an all-day beach facility: general entry is 9–11 a.m. and 2–9:30 p.m., with the same 9 p.m. last entry as Muro-no-Yu. The bath is closed on Thursdays.
The bus stops at Shirarahama, right by the beach. The bath itself is upstairs, so bring a dry change of clothes if you are coming straight from the sand.
Matsunoyu keeps the bill down
Matsunoyu charges ¥400 for adults and ¥150 for children, and opens 1–9 p.m. on days it operates. Tuesday is its regular closing day. Its simple neighbourhood-bath setup is best for a quick soak, not for an oceanfront view or an extensive bathing menu.
Meiko Bus’s Shirahama route connects the station, beach and hot-spring district. Check the current route map and timetable before trying to visit several baths in one afternoon. Their hours overlap only partly, and closures mean a town map alone will not tell you which combination is open.
For an overnight stay with a choice of in-room bath types, see Hamachidori no Yu Kaisyu’s room guide. If your route continues south, Nanki Katsuura’s day-use baths have a different mix of hotel and local-bath options.
