As symbolic building, this eight-storey structure building is split in half horizontally. The horizontal split is functional as well as symbolic, providing a simple approach to the dual functions of Embassy and leasable office space. Both have the prestigious Aoyama Avenue address in front of the Imperial Grounds. With the leasable space occupying the lower three levels, security are simplified: direct penetration into the Embassy from the outside is impossible. The glass enclosed roof shelters the Embassy offices on the upper four levels.
