Mamesaka Onsen (Mitsumineso) is a hot spring facility in Ōsaki, Miyagi Prefecture. Its sodium-chloride water flows at 41°C, pH 7.3. It offers an indoor bath, an outdoor rotenburo bath and a sauna.
Insider tip — Mitsumineso, the three peaks lodge, takes its name from the triple ridgelines of the Ou Mountains visible to the west of Ōsaki. The Mamesaka district serves a rural farming community in the gentle Miyagi basin where rice, soba, and edamame cultivation shape the seasonal calendar, and the Naruko Onsen resort district to the northwest draws visitors with its famous kokeshi wooden doll workshops.
