Why the spring water stands out
The Fukuoka tourism authority says the 65°C source is cooled through a heat exchanger rather than diluted. The indoor bath has two temperature zones; the area near the inlet is around 43°C, so test the water away from the inlet if you prefer a gentler bath. The official tourism page and the Kyushu Onsen Trail brochure use slightly different formal spring classifications; check the analysis certificate displayed on site for the latest laboratory wording.
Open-air bath and sauna
The open-air bath and sauna are included in the ¥600 admission. Current primary sources do not publish the sauna temperature, cold-bath temperature or exact amenity set, so do not plan around old review-site measurements.
Who Aoki Onsen suits
- Good for travelers who prioritize distinctive free-flowing water and a low price
- Convenient for a driving route through Jojima and Okawa
- Not suitable when a private bath, hotel or extensive dining facilities are essential
- Public transport is possible but needs time and timetable checks

A Kyushu 88 Onsen Trail stop
Aoki Onsen participates in the 2026 Kyushu 88 Onsen Trail. The half-price benefit is for certified Onsen Master members once, not a general discount for simply showing a stamp book.
Access from Kurume and Fukuoka
By car, it is about 20 minutes from Higashi-Sefuri IC. From Nishitetsu Daizenji Station, a taxi takes about 20 minutes. Another published option is a bus to Aoki Nakatsu Ohashi followed by about a 15-minute walk; verify the return timetable first.
