This is one of japan's largest parkour playgrounds for children. parkour is a movement culture that improves athletic ability while learning how to use the body properly and how to take a defensive position. there are many play mechanisms that develop the mind and body through the five basic movements of "running," "jumping," "crossing," "grabbing," and "balancing," such as the sports tag game "kids chase tag" and bornelund play equipment. no reservations are required to participate, and since it is indoors, you can play safely even in the rain.
