Saiko-no-Yu in Omuta combines a natural alkaline hot spring, four sauna types, private family baths, restaurant, gym and accommodation. It suits a car-based southern Fukuoka trip or an overnight spa stay more than a quick visit from Hakata.

Details were checked on 23 July 2026. Family baths can stop temporarily for maintenance, so confirm availability on the day.
Spring and sauna
The official site lists a pH 9.8 alkaline simple spring and 15 bath features. The 2025 sauna renewal created hybrid, steam, meditation and barrel saunas, plus three temperatures and types of cold bath. Follow posted hydration and self-loyly rules and leave immediately if unwell.
How the facility works
Place shoes in the ¥100-return locker and keep the wristband key. Bath, restaurant and other purchases are recorded to the band and paid at the machine before exit. The official site lists cash, credit cards and PayPay. Guests using the gym need indoor shoes, and children below junior-high age cannot enter the gym.
From age 7, children must use the bath for their registered sex under the facility rule. Ask in advance about tattoo, disability assistance and private-bath needs.
Stay and activities
The site also has a cabin-style hotel, trailer houses, RV camping, fishing and go-karts. These have separate reservations, prices and hours. Do not assume general bath admission includes accommodation or activities.
Access
The address is 6-37 Shin-Katsudachi-machi, Omuta, about 10 minutes by car from JR Omuta Station and 15 minutes from JR Arao Station. A taxi or rental car is the practical choice. Build it into an Omuta or Arao itinerary rather than commuting from central Fukuoka only for a short bath.
