Futai-ji (不退寺), also known as Narihira-dera (業平寺), is a Buddhist temple in Nara, Japan. The temple was opened by Ariwara no Narihira in 847, known as the author of the Tales of Ise. The temple was built over a place where it was formerly a mansion of Narihira's grandfather, former Emperor Heizei. The main hall houses a Shō-kannon (聖観音) (a form of Avalokiteśvara or Guan Yin) buddha image as its primary worship object, surrounded by five Myo-O, as well as a small Shinto shrine also inside the same building.
