Yamagata Yuza Town
"Chokai Onsen Yoyō Center Apon Nishihama" is a day-use hot spring facility in Yuza Town, Yamagata Prefecture. Its biggest draw is the cold plunge bath, which makes luxurious use of the abundant spring water that flows from Mt. Chokai. The water is astonishingly soft and gentle, with a silky quality that clings to the skin, earning high praise from sauna enthusiasts as well.
