Kobo Daishi founded the temple after Dainichi Nyorai appeared in a purple cloud during his training, declaring 'This land is a sacred place.' He carved the deity's statue on the spot and built the temple immediately.

Dainichi-ji fue incendiado durante la era Tensho por las fuerzas de Chosokabe Motochika, y luego reconstruido a principios del período Edo.

The temple's principal image switched in the Meiji era: an Eleven-Faced Kannon from the neighboring shrine replaced the original Dainichi Nyorai statue, which was demoted to a side position after centuries as the main deity.

Dainichi-ji es el Templo No. 13 de la Peregrinación de Shikoku de 88 templos en Tokushima.
