Radon Hot-Air Bathing at a Riverside Inn in Misasa Onsen
Day Use
YesOn Wednesdays, day-use bathing is afternoon/evening only (no morning session). The inn also closes a few unscheduled days most months for maintenance, announced on the official website, and bathing facilities sometimes reopen later than usual (around 15:00) the day after such a closure.
Day-use bathing is 1,000 yen for adults. Misasa town residents get a 500 yen rate with proof of address.
Bathing & Water
Uses natural hot spring water
Open-air outdoor bath
Located a short walk outside the main hotel building, beside the Santoku river; a 2024 Google review and the existing place description state advance reservation is required, though more recent (2026) reviews describe using it without mentioning a reservation step.
Enclosed indoor bathing area
Sauna room of any kind
Mist/steam sauna attached to the main indoor bath; independently corroborated by a nifty onsen listing (スチームサウナ).
