Oyakusho Administrative Office
On the west side of the building was a place called oyakusho, where officials in charge of school administration were stationed. At this administrative center, they prepared notices from their domain, placed purchase orders for goods, managed protocols for outside trainees and guests, and organized schedules for lectures and practices.
The illustration of the school at its completion shows that rooms were assigned by job title (Ometsuke, Shirabeyaku, Kakariyakunin, etc.). Adjacent to Oyakusho are Odaisu-no-ma on the south side, where they prepared refreshments when a feudal lord came to visit, and Nagairori-no-ma on the north side, which was used for meetings with officials.
