Introduction to the open-air concert in the lawn area: The lawn area is located on the east side of the park and can be reached by both viewing trails and quiet trails. This place was originally the terminus of the cableway that transported lumber, and was the distribution center where the lumber slid down. Later, due to the Toshiba disaster, it was renovated into a forest outdoor plaza. Because it is surrounded by mountains and has lush pastures, it is an excellent natural grandstand. Therefore, it has become a favorite place for various large-scale outdoor performances in recent years.
