In Okunoin, located at the highest place in Saijo-ji Temple (altitude 430m), the principal image “Ekadasamukha (eleven-faced Avalokitesvara)” is enshrined, and it is believed that it changed its appearance into Doryo-son.
In order to arrive at Okunoin, you have to go up sharp stairs that have over 350 stages, but many people climb up this stairway and offer prayers.
