Excavations at a ritual pond site in Nara Prefecture have revealed a collection of miniature 'copper-bound' wooden boats dating to the 6th century AD. These delicate models were found alongside ceremonial beads and pottery, deposited in the mud of what was once a sacred water source for the local Kofun-era elite.
Cultural historians believe these spirit boats were used in early 'Purification' festivals, where they were floated across the water to carry away the community's misfortunes. The discovery provides the earliest physical evidence for the origins of Japan's famous water-based matsuri, demonstrating that the practice of using boats as ritual vessels for spiritual cleansing has a history spanning over fifteen centuries.
