Mishiro Shrine is less than 1k from Yaguchi Shrine, and like it is also listed in the Izumo Fudoki and is a shikinaisha, a shrine receiving offerings from the central government in the Heian Period and therefore listed in the Engi Shiki.
Like Yaguchi, it enshrines Susano, but also his "wife" Kushinada, and a grandson Oyamakui, son of Otoshi. Like many of the offspring of Otoshi, Oyamakui has strong links with Korean immigrfant groups in ancient Japan. Oyamakui is the original kami of Mt Hiei and what is now Hiyoshi Taisha. Oyamakui also has connections to the Hata and kamo clans, 2 very powerful immigrant clans .
There is a zuijinmon containing a fine pair of zuijin and their attendant, small, wooden komainu which have a most definite "cute" appearance.
There are 2 smaller shrines within the grounds, an Inari Shrine, and a Takasa Shrine which enshrines Aohatasakusahiko, and all I can find out about him is that he was one of the numerous offspring of Susano.
