About this onsen
Ashinomaki Onsen is a gorge hot spring resort along the Okawa River south of Aizuwakamatsu. Past Ashinomaki Onsen Station, famous for its cat stationmaster, inns line the mountain stream. Marumine is a large inn second in scale only to Ōkawasō here, and the valley-view grand bath on the 1st floor of the main building is its signature. The spring is a salt-bearing gypsum spring (calcium-sodium sulfate-chloride), drawn from the Ashinomaki combined source, a blend of five springs.
Good to know
Day bathing is 13:00-21:00: 1,500 yen for adults and 700 yen for elementary students (towel included; toddlers free). There is a grand bath with large windows facing the stream, an open-air bath, and a sauna. A free shuttle bus runs from Ashinomaki Onsen Station on the Aizu Railway, so it is easy to reach by public transport. Weekends get busy, so weekday afternoons are more relaxed.
