Funagoya Onsen is a quiet hot-spring area beside the Chikugo River, south of Kurume. The most practical day-visit base is Koi Botaru, a roadside complex with a natural bath, free footbath, local-produce market and restaurant. It suits a slower Chikugo trip better than a rushed side trip from central Fukuoka.

What the water and baths are like
The spring is described as a magnesium-sodium-calcium bicarbonate water and is promoted locally as a “beauty bath.” The facility has indoor and open-air baths, including a reclining bath. Men’s and women’s sides switch weekly, so individual layouts differ by visit.
Access
Koi Botaru is at 298-2 Oshima, Chikugo. It is about eight minutes by car from the Yame Interchange and roughly a 15-minute walk from JR Chikugo-Funagoya Station. Train frequency is lower than in central Fukuoka; check both outbound and return times before leaving.
What to bring and bath rules
Bring a towel or confirm rental and purchase options at reception. Wash before entering the bath, keep towels out of the water and do not wear swimwear. Ask directly about tattoo rules and accessibility if needed. The mineral-rich water and floors may feel different from a hotel bath, so walk carefully.
Make it a half-day trip
The produce hall sells local vegetables and regional products, while the restaurant makes it easy to eat before or after bathing. The wider Chikugo-Funagoya area also includes riverside scenery and Kyushu Geibunkan. A car offers more flexibility, but a station-based plan is possible if you allow time.
Who should choose Funagoya Onsen?
- Travellers exploring southern Fukuoka rather than only Hakata and Tenjin
- People who want an onsen, local food and shopping in one stop
- Rail travellers comfortable with a short walk and less frequent trains
- Drivers combining Chikugo, Yanagawa or Yame
