Tsuetate Onsen, Oguni, Kumamoto
Shiraiwa Onsen Family Baths
A simple coin-operated family-bath facility where each group drains and refills the tub, using groundwater to cool the hot spring. The tourism association still lists it as open 24 hours, but a 2024 on-site report found it closed for the day; confirm before making a late-night or early-morning trip.
Check before bathing
- Opening hours

- Tattoo policy
- The current official tourism listing does not state a tattoo rule. Private-room availability does not itself confirm permission; check with the facility.
