The flow of the waterway through the local Nasu town was expressed as a promenade alongside a water feature passing through the center of the site in front of the building facades.
The promenade and water feature invites visitors to the center of the site.
The circular forum is a climactic space for guiding people to the center of the site and then to the hall building. The spiral slope that connects each facility starts from outside the circular large wall and as you gradually rise up the incline you have a constantly changing vista, which evokes a magical feeling as different views appear.
The gallery can be clearly viewed through the transparent façade by those on the promenade, allowing the current cultural messages of the exhibitions to be understood.
The lobby is a place to control entry to the main hall and relax during intermissions.
The space is especially intended for optimized acoustics for stringed instruments and utilizes a diffusing rib wall, carefully designed for blending leading sound reflections. While mainly focusing on classical concerts, the hall also supports a variety of uses such as lecture meetings and screening sessions.
The reverberation time is planned to be variable from 1.7 seconds to 2.1 seconds. Acoustic design is by Nagata Acoustic.
Multipurpose Theater Hall
The foyer is a space wrapped with a soft punched film and as you go through the door to the theater a steeply rising bank of seats appears. Each audience seat row rises by a head height to the next row securing a good view for all the audience. From the stage the audience rises steeply visibly, enhancing the presence between the performer and the audience.
