About Hyakumantō Darani

The Hyakumantō Darani (百万塔陀羅尼), or the "One Million Pagodas and Dharani Prayers", are a series of Buddhist prayers or spells that were printed on paper and then rolled up and housed in wooden cases that resemble miniature pagodas in both appearance and meaning. Although woodblock-printed books from Chinese Buddhist temples were seen in Japan as early as the 8th century, the Hyakumantō Darani are the earliest surviving examples of printing in Japan and, alongside the Korean Dharani Sutra, are considered to be some of the world's oldest extant printed matter.
