Insider tip — Koma no Yu, the horse spring, takes its name from the koma wild horses historically associated with the Tohoku highlands. Located in Kurihara near the volcanic Naruko-Osaki area, the saline spring warms travellers exploring this inland Miyagi region of river gorges and traditional kokeshi doll craft.
