About
Azuki Onsen Madoake no Yu (小豆温泉 窓明の湯) is a small day-use bathhouse in Minamiaizu. The baths are indoors only, two tubs, one hot and one milder, and the spring water is kakenagashi (源泉掛け流し). There is no rotenburo, though visitors mention that the windows open, so it feels close to bathing outside. The men's side has five washing stations, and shampoo, rinse and body soap are provided. There is a rest area for after the bath and a very large parking lot. Towels are sold at the counter, not lent.
