Hannya-ji

 is a Buddhist temple of the Shingon Ritsu sect in Nara, Japan. Its foundation is variously dated, but mention in a document in the Shōsōin provides a terminus ante quem of the mid-eighth century.
Name.
"Hannya" is a phonetic rendering of prajñā, the Sanskrit term for wisdom or insight.
History.
According to temple tradition, Ekan, a monk from Goguryeo, founded the monastic complex of on the site in 629. Emperor Shōmu is then said to have bestowed upon it, in 735, six hundred volumes of the Daihannyaharamitta-kyō, in gold on indigo paper, along with a sotōba and the name Hannya-ji.
According to "The Tale of the Heike", during the Genpei War, Taira no Kiyomori dispatched Taira no Shigehira to lead the attack on Nara, in 1180. The defenders, many of them monks, took up position on Narazaka and at Hannya-ji. When the fighting continued into the night, Shigehira ordered torches to be lit, and one of his men set fire to a nearby house. Fanned by strong winds, the flames spread as far as Tōdai-ji and Kōfuku-ji. Later Shigehira's head was nailed in front of the Hannya-ji torii, since this is where he had stood when the temples burned.
Architecture.
Rōmon.
The rōmon or "tower gate" is a National Treasure. Dated to the second half of the thirteenth century, perhaps to the Bun'ei era, it is unusual in having only one entrance, its narrowness precluding the standard three; a three bay form is adopted in the upper level.
Hondō.
The hondō with hip-and-gable roof dates from Kanbun 7 (1667) and has been designated a Prefectural Cultural Property.
Kyōzō.
The three-by-two bay kyōzō or repository for sutras, temple chronicles, and the like, dates from the second half of the Kamakura period and is an Important Cultural Property.
Tō.
The thirteen-storey stone pagoda dates from 1253 and is an Important Cultural Property.
Treasures.
Important Cultural Properties include the "hengaku" or plaque bearing the temple's name, from the Heian period; a reliquary of the Kamakura period; a pair of kasatōba from 1261; a wooden Monju Bosatsu riding on a lion of 1324; a bronze Yakushi Nyorai of the Heian period; a prayer text by Eison of 1269; and a collection of objects from inside the stone tō, dating from the Nara period to the Meiji period as well as from Southern Song China, uncovered in 1964.
