Iwamotoji is the 37th temple on the Shikoku Pilgrimage, and is reached, by foot at least, by quite long passage over the mountains. Fall colors were on full display when I arrived on my 20th day of walking.
Just to the NE of the temple is a shrine, and according to legend it was founded by Gyoki. Later Kobo Daishi came here and distributed 5 statues around various sites in the area. Many of these sites must have been shrines but when Shinbutsubunri, the separation of buddhas and kami, was implemented all five were collected here.
Usually a temple will have a single honzon, a main deity enshrined, but here there are five, Fudo Myoo, Kannon, Jizo, Amida, and Yakushi. The temple belongs to the Shingon sect.
Yeat another of the temples burnt down by the warlord Chosokabe, the current main hall was built in 1978. The ceiling is composed of more than 500 small, square paintings collected from all over Japan. The designs are not limted to Buddhist or religious themes.
