Insider tip — Nonbiri Onsen in the Koriyama basin of Fukushima Prefecture lives up to its name, nonbiri meaning carefree and relaxed, with a laid-back atmosphere and sodium-chloride waters that ease both body and mind. The spring draws from deep Tohoku geological layers, delivering reliably warm mineral-rich water favored for improving circulation. Facilities are modest and friendly, drawing a loyal neighborhood crowd of all ages. Arriving on a quiet weekday morning guarantees the most serene experience.
