Miyagase Lake, which spans three municipalities, has three areas with different attractions (Miyagase Lakeside Area, Toriihara Area, and Dam Site Area), which can be enjoyed for a day while touring around. Each area offers a variety of rides and activities. You can enjoy driving and strolling around the area while taking in the spectacular scenery.

This is an experiential facility that provides information on dams and water resources that you can learn through some fun activities. Based on the concept of "learning while having fun", this facility is filled with unique activities.
