After passing by Izumo Taisha, the route of the Izumo 33 Kannon Pilgrimage heads up a steep and narrow mountain lane. About 1k up the road is this small shrine, a sessha of Izumo Taisha.
The main kami is Onamuchi, the name of the kami more commonly known by his title Okuninushi, the Great Land Master. The second kami is Kotoshironushi, one of his sons and the main kami of the Miho shrine.
The third kami is Takahime, one of Okuninushis' daughters who married Amewakahiko the second envoy sent from the High Plain of Heaven to ask Okuninushi to hand over control of Japan to Amaterasu's line. Both the first and second envoys switched sides and joined Okuninushi and did not report back necessitating a third envoy being sent.
After this shrine, the only structure on the road up the mountain, the road continues to steeply ascend before dropping down towards the sea.
