, officially , is a Buddhist temple of the Omuro sect of Shingon Buddhism in Umegahata Toganà Âchà Â, Ukyà  Ward, Kyoto, Japan. Kà Âzan-ji is also known as Kà Âsan-ji and Toganà Â-dera. The temple was founded by the Shingon scholar and monk Myà Âe (1173âÂÂ1232) and is renowned for its numerous national treasures and important cultural properties. The Chà Âjà «-jinbutsu-giga, a group of ink paintings from the 12th and 13th centuries, are among the most important treasures of Kà Âzan-ji. The temple celebrates Biyakkà Âshin, Zenmyà Âshin and Kasuga Myà Âjin, as well as the temple's tutelary Shintà  deity.

Togano, located deep in the mountains behind Jingo-ji temple, which are famous for their autumn foliage, is considered an ideal location for mountain asceticism, and there have long been many small temples in this location. In addition to Kosan-ji, there have been other temples in the area, such as and . According to legend, these were said to have been established by the imperial orders of Emperor KÃ Ânin in 774, however, the accuracy of these claims is not clear.
In 1206, Myà Âe, a Kegon Buddhist priest who had been serving at nearby Jingo-ji, was granted the land to construct a temple by Emperor Go-Toba. He selected the name . The temple's name was taken from a line in the Avatamsaka sutra: .
The temple has been destroyed numerous times by fire and war. The oldest extant building is , which dates from the Kamakura period (1185âÂÂ1333).
Jingo-ji houses a diagram of KÃ Âzan-ji that was drawn in 1230, some 20 years after it was constructed. The diagram is registered as an important cultural property, because it shows the original layout of the temple. From the diagram, we know that KÃ Âzan-ji originally consisted of a large gate, a main hall, a three-storied pagoda, a hall dedicated to Amitabha, a hall dedicated to Lohan, a bell tower, a scripture hall, and a Shinto shrine dedicated to the tutelary deity of the area. However, all of these buildings have since been destroyed, except for the scripture hall, which is now known as Sekisui-in.
In addition to Sekisui-in, today's Kà Âzan-ji also contains a main hall (originally part of Ninna-ji, relocated to Kà Âzan-ji) and a hall dedicated to the founding of the temple, which houses an important carved wooden bust of Myà Âe. Both of these buildings, however, are modern reconstructions.
The temple possesses numerous National Treasures and Important Cultural Properties, however, the majority of them are currently on loan to national museums in Kyoto and Tokyo.
A large number of buildings, picture scrolls, carvings, furnishings and old writings have been registered as important cultural properties. The most significant among these include:
