Ushio Shrine was the last shrine I visited before heading over the pass out of the Hi watershed. It is named after the Ushio clan who had a small "castle" on top of the mountain behind the shrine. They were vassals of the Amago.
It is yet another shrine in the area that is listed in both the Izumo Fudoki, and the Engi Shiki. The main kami enshrined here is Unojihiko, the same kami enshrined at Unochi Shrine that I visited earlier in the pilgrimage.
For details I refer you to that post. It is worth mentioning that according to the myth he caused Lake Shinji to rise in an attempt to drown his father, and supposedly the water level reached this point, which is quite remarkable considering how much higher this place is than Unochi Shrine.
Within the grounds are smaller shrines to Hachiman, Inari, Ebisu, and Aragami.
From here the road forks, the road heading north goes to Suga Shrine, a major shrine connected to Susano. The road I take heads west to Kumano Taisha, once the most important shrine in Izumo, also connected to Susano.
