three ordination platforms [三戒壇] ( san-kaidan): Ordination platforms established at three places in Japan to confer the Buddhist precepts. They were situated at Tōdai-ji temple in Nara, then Japan’s capital, Yakushi-ji temple in Shimotsuke Province to the east of Nara, and Kanzeon-ji temple in Chikuzen Province to the west. The ordination platform at Tōdai-ji was established in 754, and those at Yakushi-ji and Kanzeon-ji in 761.
