Japanese Oracle Bone Divinations during the Yayoi to Heian Periods: A Review of Studies of the Last Seventy Years

Although often thought to be mostly relevant to Bronze Age China, oracle bone divination also has a rich history in Japan, primarily documented through literature and ethnographic records. In recent decades, the discovery of oracle bones spanning from the Early Yayoi (1000–400 b.c.) to Heian (a.d. 794–1185) periods has opened new avenues for research in pyro-osteomancy. These archaeological findings provide fresh perspectives on the social and cultural influences on oracle bone divination in Japan and East Asia more broadly. In this study, we review the historical, ethnographic, and archaeological studies of oracle bone divination in Japan, offering a comprehensive overview of divination practices and their broader significance.
