Guide
Iwaya-ji is a temple of the Shingon-shu Buzan school located in Kumakogen, Ehime Prefecture. It is renowned as the 45th temple of the Shikoku 88 Temple Pilgrimage. Situated at an altitude of approximately 565m, it is a stunning mountain sanctuary surrounded by massive rock walls and ancient oak forests. The primary deity is Fudo Myoo, and the temple holds a unique form of worship where the entire mountain itself is considered the object of devotion. Along the approach, countless stone Buddha statues line the path, creating a landscape that seamlessly blends natural topography with spiritual devotion.
According to legend, the temple's origins date back to 815 AD, when Kobo Daishi (Kukai) visited the area and encountered a celestial being. It is said that Kukai established the worship of Fudo Myoo, enshrining a wooden statue in the main hall and a stone statue in the rock cave of the Okunoin, effectively making the entire mountain a sacred entity. Historically, the site has been a center of faith, with records of the monk Soben visiting during the Kamakura period. Although many structures were lost to fire during the Meiji era, the Daishi-do Hall, Main Hall, and Sanmon Gate were reconstructed during the Taisho and Showa eras. Today, these buildings are preserved as precious cultural heritages that blend traditional Japanese architecture with unique stylistic elements.
