In 770, Empress Shōtoku of Japan ordered the mass printing of one million Buddhist dharani charms on paper, marking a significant moment in the history of printing and religion. This initiative aimed to promote Buddhism and provide spiritual benefits to the populace. The printing of dharani charms not only demonstrated the technological capabilities of the time but also highlighted the intersection of religion and culture in Japan. This early form of mass production laid the groundwork for future advancements in printing technology.

The mass printing of Dharani charms on paper in Japan around 770 AD is one of the earliest examples of mass printing, influencing the dissemination of religious and poetic texts. This innovation allowed for the spread of Buddhist poetry, enriching the spiritual landscape of Japanese literature.
