The performance platform of the stage is a multi-layered floor, 16.5 meters in
width and 25 meters in length. Timber was laid on a layer of rubber pads, on
which two folds of 12 mm-thick plywood were spread, and maple flooring was
installed on the top. An expansion joint was set every 600mm to compensate for
the expected expansion and contraction of the floor. For good protection of the
floor surface, highly durable paint was applied.
Such flooring structure provides the floor with resiliency, a quality favored
by dancers. The top coating on the floor helps to protect the surface when
moving heavy equipment on the stage. It is particularly effective for the
air-casters installed on the concert towers, as the air pressure can be
maintained. Also, the water-resistance of the top coating prevents the floor
from warping and makes cleaning easy.

There are five levels of galleries on each side of the stage. The
ones on stage right are used for the scenery batten operation, and the stage
left galleries are for the production lighting.
The galleries on the stage right consist of two levels used to operate the
line-sets, and three levels used to load the counterweights for the scenery. On
stage left there are a rope-rigging gallery, a plugging gallery used to support
the production lighting power supply, a dimmer rack gallery used to set up
portable dimmer racks, and two levels used as catwalks.
The concert towers, together with the concert ceiling, function
as a sound-reflective device essential for the orchestra setting. The towers
and the ceiling create a background as well, by setting off the conductors and
performers advantageously. Finished with a wooden texture and color, the
concert towers and the concert ceiling create a more relaxed atmosphere.
The concert towers are also equipped with two levels of acoustic ledges, which
provide the musicians with sound reflections important for cross-stage
communication and hearing their own musical sound.
The manually operated rigging system is known for its excellent
performance in both speediness and preciseness, and thus contributes to the
good production of performing arts.
A total of 73 manually operated counterweight line-sets are installed at
intervals of 15 centimeters on center. These line-sets were designed to lift
maximum 900 kg, however, a normal load capacity is 670 kg considering other
factors such as weighing conditions.

Installed above the forestage, this rigging device is used for
lighting and other stage effects.
The headers and legs are used to control the size of the
proscenium opening. The opening size can be adjusted between 11.3m x 9.0m at
its smallest and 16.4m x 12.0m at its largest. The headers and legs are
finished with the same material that is applied on the proscenium arch in order
to eliminate visual disparity.
The Grand Drape is the curtain at the proscenium of the stage
house. The most beautiful in shape among the various curtains in the
auditorium, the Grand Drape opens crosswise.
The orchestra pit lift is a mechanized device which provides
quite a bit of flexibility in the use of the forestage. Capable of being
positioned at stage level, the main floor audience seating level, or the
orchestra pit level, the orchestra pit lift provides the flexible use of the
forestage. A pressure-sensing tape switch is attached below the floor of the
orchestra pit lift and on the surfaces around the lift, so that the lift is
automatically stopped in case any foreign objects get jammed between the lift
and the surrounding surfaces.
The orchestra pit lift is designed to accommodate extra seating
as well. Wagons fitted with fixed audience chairs are moved onto the lift, and
the lift is placed at the main floor audience seating level, providing 70 extra
seats. The wagons use the air-caster system. When not in use, the chair wagons
are put in storage behind the orchestra pit.
A device for a more dynamic stage setting is the portable
turntable system consisting of a double doughnut-shaped portable turntable,
each 16.5 cm thick, and 7 m and 10 m in diameter respectively, with
accompanying floors. Operated by remote control, the rotating direction can be
easily changed. When disconnected, the turntable is easy to move. Also, it can
be used as a wagon with the driver detached.
