Iwaya-ji, the 45th temple on the Shikoku Pilgrimage, is located among cliffs and rock formations in the mountains of Ehime and the name of the temple itself translates as "Rock cave Temple". It was an obvious site for Shugenja. These two carved reliefs are there.
According to the legend the temple was founded by Kobo Daishi, and he supposedly carved the wooden Fudo in the main hall as well as the stone one pictured below which is located in a cave behind the main temple.
The next two photos are both at Monju-in, the 9th Bangai Temple located just south of Matsuyama.
It was from here that Emon Saburo began his pilgrimage in search of Kukai....
