This paper examines the development of the "Hashi-dono" and the ceremonies which are performed there, shedding light on the specific nature of its ritual space. At Kamowakeikazuchi Jinia Shrine, the "Mitarashi-gawa" and "Omonoi-gawa" rivers are used to create a hierarchy of sacred space, and the "Hashi-dono", straddling the "Mitarashi-gawa" river, functions as an intermediary realm. The Imperial messenger does not cross the river, making his offering from the "Hashi-dono", and rituals deeper in the shrine are conducted by the priests. The priest gives "Kaeshi-norito" (the answer of "Kamowakeikazuchi-no-kami") to the Imperial messenger from "Ganiyo", a sacred rock.
