Mibu-dera

The temple was founded in 991 by the monk Kaiken of Onjō-ji as a gift to his mother. In 1005 a memorial service was held in which the temple was given the name "Komii-dera (小三井寺, lit. "little Mii-dera")" in reference to the founder's original temple. It is said that the title "Jizō-in" was bestowed on the temple during Emperor Shirakawa's imperial visit.

The priest Engaku of the Yuzu Nembutsu school restored the temple in the medieval period. Tradition holds that he was responsible for establishing the practice of the Mibu Dai Nembutsu Kyōgen, now an Important Intangible Folk Cultural Property.

Towards the end of the Edo period, the Tokugawa Bakufu established the Mibu Rōshigumi at the nearby stronghold, the Yagi House (八木家 Yagike). The Mibu Rōshigumi were an elite public security corp that would later be known as the Shinsengumi. Mibu-dera's grounds served as the base for the organization's military and martial arts training. A bronze statue of commander Kondō Isami stands within the temple precincts, as well as a grave-site for Shinsengumi regimental soldiers. The resting place of Kondō Isami is believed to be elsewhere. Aizuwakamatsu and Mitaka, Tokyo have been suggested as possible locations.

Mibu-dera's main image was originally a half-lotus seated Kṣitigarbha statue, fashioned in the latter part of the Kamakura period, affectionately dubbed "Mibu Jizō" among the local faithful. The image was destroyed by arson along with the main hall on July 25, 1962. After the fire, a standing Kṣitigarbha statue was relocated from the head temple Tōshōdai-ji and became the temple's new main image. The main hall was rebuilt in 1967.
