Acid Pond

A natural wonder pond in Nagano. With its beautiful nature, Happo Pond is famous. In the summer, when the sky is clear and the water is clear, we will see the most beautiful view. It can be said that we can see the Japan Alps reflected in the clear water like a mirror. Even though the journey is tiring, if you see this view, it is worth it. No matter what season you come, you will get a different feeling. But enjoy the beautiful view all the way.
