A small artificial radium bath with a hillside view over Nakatsu
Day Use
YesLast entry 15:30 (bath closes 16:00). Tuesdays: no public bathing, though a private family bath can still be reserved by the hour. The facility has closed over New Year in some years without posting notice online, so it's worth calling ahead in late December or early January.
Adults 500 yen, children (age 3 to junior high) 300 yen, under 3 free. These were raised from 400/250 yen in October 2025, so some older listings may still show the previous prices. The private family bath is 2,200 yen per hour, reservation required.

About
The bath here isn't natural onsen water: it's tap water infused with an artificial radium treatment. There's just one small tub, big enough for about three people at a time, plus a washing area for four. The window doesn't open, but the room looks out over Nakatsu, and on a clear day the view reaches toward the Bungo Channel. A private family bath can also be booked by the hour on certain weekdays. Furusato Kaisokan Hachimensanso sits partway up Mt. Hachimen (八面山). It's built more for groups than a romantic soak: plain tatami rooms, a cafe serving set lunches, and a covered barbecue house, all close to the town's sports parks and gyms, so school and club teams use it as a training-camp base.
