Day Use
YesClosure days are announced month by month rather than on a fixed weekly schedule. Bathing can also be unavailable on weekdays for cleaning, or suspended after typhoons or heavy rain when the spring water turns cloudy. It's worth calling ahead (0248-84-2311) to check before visiting.
Children pay ¥700 and infants (preschool age through elementary school) ¥500, on top of the ¥1,000 adult rate (tax included). Day-use bathing is a single session, with no lunch or private-room rest included.

About
大丸あすなろ荘 sits deep in the Futamata valley of Fukushima, a member of the Japan Secret Hot Springs Association and reportedly first discovered in the Heian period. The simple alkaline spring (pH 7.6) feeds three different baths, including a self-flowing rock bath where the water bubbles up naturally through the bottom of the tub, a rare and oddly mesmerising thing to sit in. The stream-side open-air bath changes face with the seasons, and the mixed bathing hours during daytime day-trip visits add to its unhurried, backcountry character.
