CHIBA PREFECTURE, JAPAN—The Asahi Shimbun reports that a piece of a runner from a wooden sledge was discovered in the moat surrounding Hamanaga-Suga burial mound cluster, which is located near the eastern coast of the island of Honshu. The 1,400-year-old runner fragment, made from the wood of the muku tree, measures about 55 inches long. Such V-shaped sledges, known as shura, are thought to have carried materials such as heavy stones used to build the burial mounds at the site.
