This large structure faces east, has 8 bays from north to south, and 4 bays from east to west, and was built using plain wood. The eastern 2 bays are the main part of the hall, where the “Naorai” ceremony for imperial representatives is held during the Kasuga Festival. The building is also called “Hakko-ya”, because during the Heian Period and afterwards (early 12th century), the “Hokke Hakko” (a ceremonial series of eight lectures on the eight scrolls of the Lotus Sutra) used to be held here, which drew large audiences.
