A colossal stage where idols prove their worth to thousands of cheering fans.

While it opened preliminarily on May 5, 2000, its official opening followed on September 1 of the same year. Designed by Dan Meis and Nikken Sekkei after an international competition, the venue features a gigantic movable seating section to adjust capacity for smaller events. With a maximum capacity of 36,500 and a main arena range between 19,000 and 22,500, it stands as one of Japan's most versatile performance spaces.
