Japan's new national theater is not as luxurious as we thought, nor as grand as Lincoln Art Center in Washington, USA. Part of the exterior wall of Seoul Art Hall in South Korea is still cement wall, but its interior is carefree and bright, which makes people feel very comfortable. In particular, the area of the audience lounge is much larger than that of domestic cinemas. Unlike most cinemas in China, the seats in the lounge for the audience to rest are solid wood benches, which are both sanitary and economical. The decorative materials that the theater contacts with the audience are more exquisite, but the colors are not gorgeous. Places that are not in contact with the audience are decorated simply, and some are only covered with particleboard. Every theater is equipped with passages and seats for the disabled. The row spacing of cinema seats is generally 95cm, and the seat spacing is 55-60 cm. The floor of the audience hall in Japan is mostly solid wood. Walking into the theater is like walking into the family, which makes people feel warm. The floor, wall and floor of the backstage auxiliary room of the audience hall are deeply coated with fireproof paint.
