Saitama Super Arena is a multi-purpose indoor arena located in Chūō-ku, Saitama, Saitama Prefecture, Japan. It opened preliminarily on May 5, 2000, and then was officially opened on September 1 of the same year. Its maximum capacity is 36,500, making it the third-largest indoor arena in the world. The main arena capacity is between 19,000 and 22,500.
The arena was designed by Dan Meis, who at the time was working for architecture firm Ellerbe Becket, together with Nikken Sekkei. Meis's design was selected as a result of an international design competition. The arena features a gigantic movable section of seating which can reduce capacity for smaller events and create a more intimate setting.
