Kannonji City in Kagawa Prefecture uniquely has two Holy Sites of Shikoku in one premise; Jin’nein Temple (the 68th) and Kannonji Temple (the 69th). These temples were originally a part of Kotohiki (Harp Play) Hachimangu Shrine founded in 703 by Priest Nissho, who had received a divine message from Hachiman Daimyojin with the tune of Japanese harp heard from a boat on the sea. Jin’nein was also built at this time as an attached temple to the shrine.

In the Daido era (806-809), Kobo Daishi enshrined Amida Buddha、which was Honjibutsu (Buddhist counterpart of the deity of the shrine) and designated the shrine as the 68th of the 88 Holy Sites of Shikoku. Then he carved Sho Kanzeon Bosatsu (Sacred Form of Kannon) and built the formal seven buildings of a temple in the nearby mountain, and named it Kannonji Temple, which was designated as the 69th.

Later in the Meiji period (1868-1912), when temples and shrines were separated according to the Shinbutsu Bunri policy of the national government, Honjibutsu Amida Buddha of Kotohiki Hachimangu Shrine was removed to Nishi-Kondo Hall of Kannonji Temple, which became the main hall of Jin’nein Temple; hereby two temples has been located in the same premise since then. Jin’nein temple is up the stone steps from Kannonji Temple.
