Azuki Onsen Madomei no Yu is located in Minami-Aizu-machi, Fukushima Prefecture. Its iron-rich water flows at 42°C, pH 6.3. Facilities include an indoor bath, an outdoor rotenburo and a sauna.
Insider tip — In the deeply rural southern Aizu valley of Fukushima, where ancient mountain traditions and Jomon-era heritage sites dot the landscape, Madomei no Yu (framed-view spring) is named for the spectacular mountain panoramas visible through the bathhouse windows; the reddish-iron waters carry the mineral character of the rugged Minami-Aizu hills in every soaking session.
