SAITAMA SUPER ARENA: THREE BUILDINGS IN ONE
Depending on when you go there, the new sports and cultural facility for the Saitama Prefecture, Japan, is a 30,000-seat soccer stadium, a 20,000-seat basketball arena, or a 5,000-seat concert hall. The technology that makes these transformations possible is a unique system for moving a very large block of 9,200 seats, with related walls, floors, and spectator amenities. The block is 135 feet (41.5 meters) high and weighs 15,000 tons. In only 20 minutes it can move the 230 feet (70 meters) between the arena and stadium configurations.
