Oki-no-Yu Aqus is a public wellness complex in Oki Town, south of Fukuoka City. One admission covers both the natural hot-spring baths and the heated indoor pool, making it useful for families and rainy-day travel around Yanagawa, Okawa and the Chikugo area.
Price and hours
| Bath complex | 10:00–22:00 |
|---|---|
| Pool | 10:00–21:00 |
| Adult, junior high and older | ¥600 |
| Child, age 3 and older | ¥350 |
| Locker | ¥10 |
Admission includes the bath and pool. Children cannot enter alone and must be accompanied by an adult aged 18 or older who also pays admission. Check the official calendar for closure days and the weekly switch between the Japanese- and Western-style baths.
Bath and pool facilities
The natural spring emerges at 52.9°C and the official site describes an overflow system that does not recirculate used overflow water. The two bathing zones alternate between men and women and include open-air baths, dry sauna, cold bath and massage-style baths.
The pool area includes exercise, care and children’s pools, a mist sauna and jacuzzi. Bring swimwear and a swimming cap and follow the on-site lane and age rules. The pool is not an outdoor resort pool.
What to bring
- Bath towel and face towel
- Swimsuit, cap and a bag for wet items if using the pool
- Small coins for lockers and vending machines
- Easy clothing for changing twice if combining pool and bath
Confirm current tattoo, flotation-device and child-supervision rules directly with the facility before making a long trip.
Access and trip planning
Aqus is at 538-1 Hachomuta, Oki Town, Mizuma District. Car access is the practical choice for most visitors. Combine it with Yanagawa sightseeing, local steamed eel or an Okawa furniture-area drive rather than treating it as a quick stop from central Fukuoka.
