Shichagui（First Floor of the Seiden）

The first floor of the Seiden was referred to as Shichagui, and this was where the King himself mainly led the ceremonies. The lavish area at the center was called the Usasuka, the royal throne where the King presided for various ceremonies. Through the sliding Shoji screens behind the Usasuka is the Ochokui, a set of stairs used exclusively by the King, and it was from these stairs that the King arrived to the Usasuka from the second floor.
Destroyed by the fire in October 2019.
