Autumn LeavesLake ViewsScenic DrivesCamping

Minowa Dam is known as Momiji Lake for roughly 10,000 maple trees planted around its blue reservoir. The remote mountain road, event areas and nearby Tarusawa campground require advance transport planning, especially during the crowded late-autumn colour period.
