Jinzu Onsen

Jinzu Onsen, located deep in the mountains in a cedar forest, is an artesian ion hot spring. The color of the spring water changes depending on the earth's atmospheric pressure, the ocean's high and low tides, and the centrifugal force of the earth's rotation. The view from the window is full of nature, and you can even spot wild animals such as ducks and wild boars. There is a walking course near the hot springs, and you can see fireflies dancing in early summer.
