The Politics of Buddhist Artifacts: Tribute and Bestowal Between Heian and Northern Song

During the Northern Song period, the gifting of Buddhist artifacts frequently appeared in Sino–Japanese exchanges. Although Japan had established a self-centered order with its emperor at its core and tended toward isolation, the Heian imperial court, led by the Fujiwara regents, actively dispatched monks to Song China and requested Buddhist artifacts. Although these monks were not official envoys, they reflected a trend toward diversified diplomacy in Japan. Recognizing the close ties between these monks and the Japanese rulers, the Song court used the bestowal of Buddhist artifacts to encourage them to convey messages to the Japanese court, urging Japan to send formal tribute missions and thereby incorporating this into its broader diplomatic strategy. Under the “Chanyuan Treaty System”, Buddhism served as a shared cultural foundation for transregional interaction in East Asia. By collecting and bestowing Buddhist artifacts, the Song Dynasty proclaimed its orthodox status within the Buddhist world and enhanced its diplomatic influence. However, the Heian court, upon receiving these artifacts, repurposed them to construct their own divine authority and vision of a “Land of Buddha’s Kingdom”. Thus, the very same set of Buddhist artifacts carried vastly different symbolic meanings and functions in the Northern Song–Heian diplomatic interactions.
