Kōzan-ji (高山寺), officially Toganōsan Kōsan-ji, is a Buddhist temple of the Omuro sect of Shingon Buddhism in Ukyō Ward, Kyoto. Founded by the monk and scholar Myōe (1173–1232), it is known for its national treasures, important cultural properties, and association with the UNESCO World Heritage Site Historic Monuments of Ancient Kyoto, inscribed in 1994. Its best-known treasure is the Chōjū-jinbutsu-giga, a set of 12th- and 13th-century ink paintings. The temple also venerates Biyakkōshin, Zenmyōshin, Kasuga Myōjin, and its tutelary Shintō deity, reflecting its Buddhist-Shintō history. The temple is also called Kōsan-ji and Toganō-dera. Specific buildings named in the source are not listed beyond the temple complex itself, but Kōzan-ji is an important stop in Kyoto’s religious and cultural landscape.
