Amida-ji Temple, Buddhist temple in Sakyō-ku, Japan.

Amidaji is a Jōdo-shū temple in the Kōchidani area of Ōhara, Sakyō-ku, Kyoto. Its grounds climb a steep hillside: a Chinese-style two-storey gate with white plaster on the lower level, a main hall, the stone mausoleum of founder Tanshō, a tea house, a waterfall and a treasure hall. A small wooden bell tower with a dark tiled roof and four plain posts stands among the trees.

The temple was founded in March 1609 by the monk Tanzei, a native of Owari Province who left home at nine and travelled the provinces before settling at Kochidani in Ōhara. Tanzei died here on 23 May 1613, aged 62, and is said to have entered a stone coffin as a self-mummified Buddha; his remains lie in a rock hollow beside the main hall.

The main hall holds two principal images: a Kamakura-period wooden seated Amida Buddha on the right, an Important Cultural Property, and a self-carved statue of the founder Tanzei into which he is said to have embedded his own hair. Because both are venerated, the temple calls itself the sole head temple of the Tanzei Buddha lineage, unlike most Jōdo-shū temples, which honour Amida alone.

Reach the temple by bus from Kokusaikaikan Station to the Kochidani stop, then walk about 15 minutes up a very steep approach path after passing through the gate. Because snow makes the path dangerous, visiting is suspended each January and February; on the first three days of the New Year it is open only when there is no snow. A car park for large vehicles sits beside the gate, while ordinary cars can drive up to just below the temple.

The temple keeps the sokushinbutsu of its founder Tanzei, who died in 1613 and was placed in a stone coffin in a rock hollow beside the main hall. It is considered Japan's southernmost and westernmost self-mummified monk, but it has not been shown publicly since being sealed in the present coffin in the early Meiji era. Visitors can walk right up to the coffin.
