Designed by world-renowned architect Isozaki Arata, the exterior and interior of this beautiful concert hall elegantly combines simple design principles with sophisticated function. The main floor of the hall is done entirely in limestone imported from Kyoto's Italian sister city Florence. The Concert Hall (Main Hall) can seat up to 1,833 people, and The Ensemble Hall Murata (Small Hall) up to 510. Used for traditional and classical music performances, both halls include the most sophisticated acoustical designs. A unique pipe organ, with both metal and wooden pipes (the largest of its kind in Japan) can create both classical instruments and the traditional Japanese instruments.
