Mii-dera (三井寺)

Mii-dera is station 14 on the Saigoku Kannon Pilgrimage, a Tendai Buddhism, Saigoku Kannon devotion temple in Shiga dedicated to Nyoirin Kannon. 672 CE (traditional founding by Emperor Tenmu in honor of his brother Emperor Tenji) Mii-dera holds three springs ('mii' = three wells) used since antiquity for the ritual bathing of imperial newborns, marking the site as a place where Buddhist sanctity and the imperial body intersect.

To approach Mii-dera is to enter a working Nyoirin Kannon hall on the Saigoku Kannon Pilgrimage — temple 14 in a thirty-three station route that has organised Kansai Kannon devotion for more than a thousand years. Mii-dera holds three springs ('mii' = three wells) used since antiquity for the ritual bathing of imperial newborns, marking the site as a place where Buddhist sanctity and the imperial body intersect. The vast hillside complex above Lake Biwa is also revered as a setting for esoteric Tendai practice and the famous 'Evening Bell at Mii-dera' (Mii no Bansho), one of the Eight Views of Ōmi.

672 CE (traditional founding by Emperor Tenmu in honor of his brother Emperor Tenji) Founded by Emperor Tenmu in 672 in memory of his brother Emperor Tenji, who died in the succession dispute that triggered the Jinshin War. Two centuries later, Enchin restored the site and renamed it 'Temple of Three Wells' for the springs that had bathed Emperors Tenji and Tenmu and Empress Jitō.

As a Tendai Buddhism (Jimon school) site, Mii-dera is the head temple of the Jimon sect of Tendai Buddhism, the branch tracing its lineage to Enchin (814–891). The Jimon-Sanmon split with Enryaku-ji in the late 10th century shaped centuries of Japanese religious and political history. Three sacred springs continuously revered for over 1,300 years Famous evening bell counted among the Eight Views of Ōmi Hillside vista over Lake Biwa, Japan's largest freshwater body Location of one of Japanese Buddhism's most consequential schisms

The Kannon-dō was relocated in 1481 so lay women could approach the Nyoirin Kannon, embedding the temple in Saigoku Kannon devotion.

Mii-dera is the institutional anchor of Jimon Tendai and a key witness to the political-religious history of Heian and medieval Japan, including the Jimon-Sanmon rivalry, the rise of warrior monks (sōhei), and repeated cycles of destruction and rebuilding. Tendai Jimon teaching emphasizes Nyoirin Kannon as a wish-granting embodiment of compassion accessible through esoteric ritual; the three wells are understood as material proof of the Buddha-Kannon's pact with the imperial line.

In Tendai esoteric (taimitsu) practice, the wells, bell, and Kannon-dō can be read as a triad of pure water, pure sound, and pure form — three sensory gates that condition awakening.
