Mudō-ji Temple, Buddhist temple in Sakamotohonmachi, Japan

Mudō-ji, formally Mudō-ji Myōō-dō, is a Tendai temple in the Mudō-ji valley of Enryaku-ji's East Pagoda area on Mount Hiei. Its main hall, the Myōō-dō, is a wooden building with a large dark-gray tiled roof and ornamental ridge figures. Below the deep eaves, the aged brown wooden facade has a wide central bay flanked by sliding doors with white rectangular panels, supported by thick square pillars. A stone lantern inscribed with characters stands to the left, with a low wooden fence and stone steps in the foreground.

Founded in 865 by Sōō, the monk credited as the founder of the thousand-day circumambulation practice, Mudō-ji became a Tendai branch temple by imperial order in 882. Under its abbot Kankei it gained influence comparable to Enryaku-ji's East and West Pagoda areas. It burned in Oda Nobunaga's 1571 raid on Mount Hiei and again in an 1843 fire, and was rebuilt after each.

Mudō-ji is the base for the thousand-day kaihōgyō practice, and its resident monks, called rinban, must have completed the full walking pilgrimage or be in the middle of it. The main image of Fudō Myōō is said to have been carved by the founder Sōō himself after he had a vision of the deity at the Three Falls of Katsuragawa Myōō-in, the temple's okunoin.

The nearest station is Cable Enryaku-ji Station on the Hieizan Railway; from there the temple is about a ten-minute walk south. The address is 4220 Sakamotohonmachi, Otsu, Shiga Prefecture. The approach is on foot, so allow for the walk when planning the visit.

Mudō-ji is the base for the 1,000-day kaihōgyō practice, and its honzon is a Fudō Myōō statue said to have been carved by Sōō himself after he had a vision of the deity at the San-no-taki waterfall of Katsuragawa Myōō-in. The temple is also called "Minami-dake" and is counted as the 26th site of the Kinki 36 Fudō pilgrimage.
