The temple of Ninna-ji was built at the end of the 9th century. At first it was known as the Monseki-ji, which served as the residence of members of the Imperial family who entered the priesthood. Presently, the temple is the center of the Omuro sect of Shingon Buddhism. It was designated a World Heritage Site in 1994.
The abbot was traditionally a member of the Imperial family, and his quarters are called the Goten,built in the Heian Period imperial style
Ninna-ji's first abbot was a direct student of Kobo Daishi, legendary founder of the Shingon sect
It can be accessible by train.
Ninnaji is a few minutes walk from Omuro Ninnaji Station on the Keifuku Kitano Line. The temple is a ten minute walk west of Ryoanji Temple Much of Ninna-ji was destroyed by fire in the Onin battles of the 15th century. As the reconstruction coincided with the rebuilding of the Imperial Palace at the beginning of the 17th century, the temple received imperial support, with many buildings moved here from the Imperial Palace grounds. Among these buildings are the Kon-do, designated as a National Treasure, and the Miedo, designated as an Important Cultural Property. Other important Cultural Properties include the Nio-mon (a gate with Buddhist images on either side) and the five-storied pagoda.
The Reiho-kan contains a number of cultural properties such as sculptures, paintings, and ancient documents. Also housed here is a seated figure of the Amida-Nyorai Buddha, who presides over Buddhist paradise. The statue is the central focus of religious worship at the temple.
