You can see the fantastic scenery as the thawed water from the Iide mountains flow into Lake Shirakawa, and the fresh green white willow trees are standing amidst the water.

It is a spectacular view of spring that can only be seen for about a month from mid-April to mid-May.

In addition, there are a campground, a park golf course, a canoe boarding area, etc. in the park nearby so you can enjoy the outdoors with your family and friends.
