This hall was designed originally as an opera house and opened in 1961. The hall was also used as a concert hall with its movable orchestra shell on the stage. Acoustical design was done by the team at the technical research laboratory of NHK (Japan Broadcasting Cooperation) including Dr. Minoru Nagata (before his Nagata Acoustics establishment). The hall was highly accepted by both of audience and musicians and used as a main concert space in Tokyo until the opening of the Suntory Hall in 1986. The hall was recently renovated mainly to reinforce the capabilities as an opera house by extending the back stage area and by introducing the state-of –the-art stage equipment. The acoustical design of the renovation was done by Nagata Acous-tics, and the goal of the acoustical design of the renovation was to keep the original excellent acoustics.
