Sanja Shrine is right next door to Manpukuji and I came into the shrine from a trail that lead from the temple.
Sanja means " Three kami", and the three enshrined here are Izanagi, Hayatamano, and Kotosakano.
Izanagi is well known but the other two are known only in an alternate version of the myth that has Izanagi visiting his deceased wife Izanami in the underworld, Yomi. When he left Yomi Izanagi swore and oath of divorce from Izanami, he then spat. From the spittle was created Hayatamano who is the main kami of the famous shrine with his name in Kumano.
Also appearing at that time was Kotosakano, full name Yomotsu Kotosakanoo, which means " The man of words of separation of Yomi". I have encountered this triad of kami at other shrines in Izumo and Iwami.
Also enshrined here is Oyamakui, a grandson of Susano through Otoshi, and the main kami of Hie Taisha and Sanno Shinto. There is also an Aragami-sha, pictured above.
This area I am walking through is at the heart of Orochi country, and according to local people following the destruction of Orochi by Susano the people danced a celebration at this spot that later became this shrine.
