Abstract
I indicated that the plan of the earthen wall with brick tiles on the Former Imperial Audience Hall of State Compound in Nara Imperial Palace was designed with three concentric circles and the eccentric circle , and this structure is similar to the astronomical chart of mural of Kitora Tomb. On this report, we can find the Chinese ancient thought that the buildings and the layout of establishment in the Palace area imitate the cosmos in the MONSEN anthology. The planners appreciate that the throne Takamikura was located at the center of the world and the throne fit on the ornament ceiling. The pair forms the turning pole Ame-no-Mihashira. On the Former Imperial Audience Hall of State Compound in Nara Imperial Palace, the number on the plan related to the calendar and the cosmos. This design show that Tennou manages the time and the cosmos in his national land same as Chinese emperor.
