Get totonou from the core with the hot saline spring and hot spring water bath

Yamagata Tsuruoka City

"Naganuma Onsen Popponoyu" is a day-use hot spring facility in Tsuruoka City, Yamagata Prefecture. Its biggest draw is the extremely high salt concentration of its spring water, a highly concentrated saline hot spring. It offers exceptional heat retention, warming the body all the way through to the core. The sauna is a far-infrared type, so you can enjoy a slow, thorough sweat. It also features a rare cooled hot spring water bath made by chilling the saline spring, allowing for a cool-down experience you cannot find elsewhere. The Japanese-style and Western-style bath areas alternate daily for men and women, and together with the open-air baths overlooking panoramic views of Mt. Chokai and Mt. Gassan, this is a facility where you can enjoy a luxurious bathing experience.
