Its breathtaking size and unique design have made the Tokyo Government Building the new face of Tokyo that everybody knows today. The most advanced technologies were poured into this building, which stands as the information base of the metropolitan government, and a seat of cultural exchange for the people of Tokyo. Of greatest importance are the building’s disaster prevention facilities. TOA supplied its highly efficient, computer-controlled Emergency Broadcast system to ensure smooth and accurate communication. Prominent among the host of other systems supplied are mobile PA systems that can be easily moved and adapted to various applications, ranging from the smallest conference room to the observation decks. Through such efforts, TOA actively promotes both confidence and comfort in this building.
