A century-old private source and eight family baths: Ureshino’s all-in-one day spa
Hyakunen-no-yu (“hundred-year bath”) is Ureshino’s only public bath with its own source — the Motoyu spring opened in 1915 and used ever since — and its ageing building was replaced with a modern one in 2016. It showcases Kyushu’s “family bath” culture with eight private rooms, two of them open-air, letting couples and families have the beauty water to themselves in 50-minute slots; add the main baths, rotenburo, sauna, a restaurant serving onsen yudofu set meals, massage and private rest rooms and you can easily spend half a day. At ¥690 on weekdays it is about half the price of ryokan day bathing (¥1,100–1,500). If Siebold’s Bath is the nostalgic public bathhouse, this is the convenient spa — right in front of the bus centre, easy even with luggage.
Tips & cautions
- Family baths are first-come, no booking; weekend afternoons can mean an hour’s wait — arrive in the morning. Online prepaid tickets (e.g. ¥630 weekdays) and JAF discounts exist.
- Surcharges on weekends, holidays, Obon and New Year.
- The restaurant closes 14:00–16:30 on weekdays; yudofu set plans need booking.
- Closed 4th Wednesday, but this shifts some months — check ahead.
- 19:00–20:00 is relatively quiet.
- Ureshino-Onsen Shinkansen station is over 2 km from the town — take a bus or taxi.
