Saitama Super Arena

Saitama Super Arena is one of the largest multipurpose arenas in Japan, boasting one of the world's largest movable seating systems. Owned by Saitama Prefecture, it is operated by the third sector company Saitama Arena Co., Ltd. The arena employs the "Moving Block System," which allows the seating, floor, and ceiling to be adjusted, enabling it to transform from a hall accommodating 6,000 people to a stadium that can hold up to 37,000 depending on the event scale. This flexible structure allows it to host a wide variety of events, including concerts, sports tournaments, trade shows, lectures, and shareholder meetings.

The facility features four modes: Stadium, Main Arena, Community Arena, and Exhibition Hall. The Stadium mode can accommodate up to 37,000 people and is used for combat sports, large concerts, and trade fairs. The Main Arena, with a capacity of 22,500 seats, is ideal for sports events such as basketball and volleyball, as well as music live performances. The Community Arena is used for local events, exhibitions, and flea markets, while the Exhibition Hall (approximately 4,000 square meters) caters to industrial displays, corporate events, and meetings.

Inside the arena, there is also a sports gym called "Jexer Fitness Studio Saitama Super Arena" and "NHK Culture Center Saitama Arena Classes," making it a beloved community interaction hub. In local publications, it is often abbreviated as "Saitama Arena," "SSA," or "Tama A," and it is affectionately called "Super Arena" by locals.

Additionally, every New Year's Eve, it hosts major events such as the mixed martial arts competition "RIZIN," and is widely known as a "sacred place for martial arts." The architectural design was handled by Nikken Sekkei, and the design, which achieves excellent acoustic performance and comfortable visibility, has received high praise.

Moreover, a large-scale renovation is scheduled to begin in January 2026 and will last for up to a year and a half, drawing continued attention as the arena evolves further.
