Zenjoji is both the 10th temple of the Izumo 33 Kannon pilgrimage and the twenty fourth temple of the Chugoku 33 Kannon Pilgrimage. It is a mountain top temple and has a fine pair of nio in the niomon at the base.
It is believed to have been founded by Gyoki which would put it in the early eighth century.
It is now a Tendai temple. There were 4 small shrines within the grounds including an Inari and one to Zaogongen.
It is quite a pretty temple and of course has superb views.
