Onzanji Temple, Sanuki Travel Guide

Onzanji Temple, officially named Boyōzan Hōshuin Onzanji, is a revered site on the Shikoku 88 Temple Pilgrimage. Founded in the 8th century by the monk Gyoki under the order of Emperor Shomu, it was initially named Dainichisan Fukushoin Mitsugonji. The temple's principal image is a statue of Yakushi Nyorai, the Medicine Buddha, believed to protect people from calamities and epidemics.The temple's history is intertwined with the story of Kobo Daishi, who practiced asceticism here in the 9th century. His mother, Tamayori Gozen, traveled to visit him, but women were prohibited from entering the temple grounds at the time. Kobo Daishi performed esoteric rituals for seven days to lift the ban, after which his mother was welcomed. She then dedicated herself to the temple, cutting her hair and becoming a nun. In honor of Kobo Daishi's filial piety, the temple was renamed Onzanji, signifying gratitude to one's parents.Onzanji is also known for its beautiful natural surroundings, located in a Prefectural Designated Scenic Area. A notable feature is the Biranju tree (Prunus zippeliana) near the main gate, said to have been planted by Kobo Daishi to commemorate his mother's dedication. The temple was destroyed by fire during the Tensho era (1573-1592) but was rebuilt during the Edo period with the support of the Hachisuka clan. The current main hall and Daishido were constructed during the Bunka and Bunsei eras (1804-1830). Today, Onzanji continues to be a significant site for pilgrims and those seeking healing and gratitude.
