In addition, the "Adventure Forest" and the "Fluffy Dome" are equipped with large playground equipment that allow children to play all day long, and during the water season, the "Jabu-Jabu Pond" is filled with the sound of children's cheers all year round. From April to November, the park is used as a base for observing the dynamic discharge of the Miyagase Dam, and the "Ai-chan-go" road train, popular with children, runs from in front of the Park Center to below the dam.
