Radiocarbon wiggle matching method was applied for precise dating of a tephra which was designated as\none of the important key beds for archaeology. The FA tephra is a pyroclastic deposit from the Shibukawa\neruption of Haruna Volcano during the Kofun period of Japan. The age of FA has been investigated using\narchaeological remains and also historical records of Japan and China. It has been estimated roughly as early\n6th century. Three tumbled logs were found being buried in the tephra whose thickness was about 4 m. The\nlogs were cut in many groups with five tree rings and every two groups were sampled for????????C measurement. As\nthese trees were thought to have the same age from the occurrence,all data were used for wiggle matching\nanalysis. The age of the outermost tree ring group is determined as AD 491-500(AD 497/+3/-6).
