Narugo Onsen in Osaki, Miyagi prefecture, is Tohoku's largest onsen resort and the production center of the beloved kokeshi wooden doll tradition, where local craftsmen have carved these simple cylindrical dolls in the onsen town's workshops for over 150 years as both folk art and souvenir of thermal culture. The iron-bearing mineral waters, ranging from milky white to pale blue in different spring sources within the compact onsen district, are prized for skin beautification and rheumatic therapy. Narugo Gorge — accessible from the onsen town — offers one of Tohoku's finest autumn foliage displays, when the forested canyon walls turn gold and crimson above the therapeutic steam of the onsen hot springs.

Insider tip — Narugo Onsen in the Tohoku mountains is the spiritual home of kokeshi wooden dolls, and its whitish bicarbonate spring water at 40°C has been flowing from volcanic vents along the Narugo gorge for over a thousand years. The narrow gorge is particularly spectacular in November when maple and beech trees turn the canyon walls crimson and gold above the steaming bathhouses. Many ryokan here operate private kashikiri baths bookable by the hour — ideal for first-time onsen visitors.
