Among the three gates along the west cloister, Keiga Gate is the furthest south. This gate was once the official entrance to the shrine. Upon passing through it, one can see Mt. Mikasa, which had been considered a sacred mountain even before the Main Sanctuary was built. Unlike the two other gates along the west cloister, this gate has a coffered ceiling. Today, if an imperial representative is from the Fujiwara family, the person enters the shrine through this gate when they come to attend the Kasuga Festival.
