Takaoyakuō-ji is a Buddhist temple situated on Mount Takao. Its full name is Takao-san Yakuō-in Yūki-ji. It was built by Gyōki on the command of Emperor Shōmu. The site had formerly been considered a holy mountain and attracted many Shugendōshi, Japanese mountain ascetic hermits practicing the strict doctrine of Shugendō. The temple was named yakuō, for it enshrines Yakushi. The temple offers a glimpse of Shinbutsu shūgō, the fusion of Buddhism and Shinto, as it contains Shinto style buildings and Torii.
