The priest's quarters are built directly into the side of a towering cliff, making Iwaya-ji one of the most architecturally daring temples on the entire 88-temple pilgrimage route.

Iwaya-ji è il Tempio n. 45 del Pellegrinaggio degli 88 Templi di Shikoku.

The temple precinct was designated as National Scenic Beauty, and its Daishi-do hall became a National Important Cultural Property in 2007, recognizing both natural and architectural significance.

At over 600 meters altitude, winter temperatures regularly drop below freezing, transforming this mountain temple into a snowy sanctuary that pilgrims brave in the early morning hours.
