It is wide enough for two regulation-size basketball and volleyball courts and can accommodate 2,000 attendees during ceremonies. There is also a 160-meter indoor circular running course. The aim was to create an environment in which high school students could feel the enjoyment of playing sports while experiencing natural light and breezes with all of their senses. The arena is constructed of a pair of 22-meter aperture portal-type earthquake-resistant frames and four pairs of U-shaped earthquake-resistant walls, with 35-meter box truss girders placed on top, bound together by the roof and floor slabs of the circular running course located seven meters above the ground. The resulting frame plan has gaps in both horizontal and vertical directions. The attached facilities have been provided as separate structures, with the building environment of light and breezes and see-through sections created by the large frame and the gaps in that frame, in order to create a design in which the form embodies the environmental performance of the building.
