Aizu Minami Onsen Sato no Yu is located in Minami-Aizu, Fukushima Prefecture. Its sodium-chloride thermal water, around 40°C (pH 7.3), fills an indoor bath, an outdoor rotenburo and a sauna.
Insider tip — Minami-Aizu (Southern Aizu) occupies the deepest and most remote highland zone of western Fukushima — ancient cedar forests, pristine rivers, and mountain communities where traditional crafts (Aizu lacquerware, Echigo-Aizu washi paper) survive unchanged. This is Tadami River headwater country; the beech forests here are primeval. Sato no Yu (Village Spring) is the community center around which Minami-Aizu's scattered hamlets gather, particularly in winter when snowfall can exceed 3 meters and the outdoor world becomes a landscape of profound white silence.
