Narugo Onsen is one of the most celebrated hot spring resorts in Miyagi Prefecture, located in the mountain town of Narugo within the city of Osaki, where sulphurous thermal waters renowned within a long thermal tradition have attracted visitors for over a thousand years to one of Tohoku's most storied onsen destinations. The high sulphur and mineral content of Narugo's springs—varying across the resort's multiple source types—is associated with well-being and the softness it leaves on the skin, establishing this as one of the premier onsen areas in northern Japan. Narugo is equally famous as the birthplace of kokeshi, Japan's traditional wooden dolls, and the workshops of master artisans line the spa town's streets, making a visit here a dual immersion in Japan's craft heritage and its ancient geothermal bathing culture.

Insider tip — The 39°C waters of Narugo Onsen Osaki are especially valued for soothing joint pain and skin conditions.
