Okuiizaka Aanabara Onsen Yoshikawa-ya

Okuiizaka Anabara Onsen Yoshikawa-ya is a ryokan in Fukushima's Iizaka hot-spring area, right along the Surikami river. The two open-air baths swap between men and women morning and night, and the shared bathing halls include a sauna; the indoor bath is named after a local legend about how the spring was first found. The water comes from the inn's own source. There's also a foot bath on the grounds and a reservable private bath called Yuno (湯野), with its own indoor and outdoor tub, and five guest rooms have their own outdoor onsen bath. Guests often mention the quiet, away from city noise, with the river running just outside, and the inn leans family-friendly, with a play space, kids' meals and baby gear on loan. Day-use bathing is offered on Sundays.
