 note = {Large-scale landslides occurred repeatedly on the western and southern slopes of Mt. Ibuki, Shiga Prefecture, central Japan, and dammed up the upper Anegawa-river (Kojima et al., 2006). Large-scale landslides have been often triggered by huge earthquake and/or torrential rain events. Precise dating of the damming is important because Mt. Ibuki is located in the periodic inland-type huge earthquake area in central Japan. To determine the timing of landslide-damming event, we carried out ^<14>C dating of leaf, twig and stock-fragments, and collection of folklore of Mt. Ibuki area. The Anegawa-river runs through the V-shaped valley named as Semiai-Kyokoku where the debris was excavated. A river terrace spreads out more than 3km from Semiai-Kyokoku along the Anegawa-river. The exposed sedimentary succession consists mainly of a silt layer. Chronological samples obtained from same sedimentary layer and calculated the calendar age; the samples show 3020-3370 cal BC (early Jomon Period). The stories in the collected folklore suggest the landslide-damming and the end of dammed lake. Some of characters in the stories considered to be based on real parsons who lived in the 11-14 century. In general, the folklore is possible to pass down over several hundred years. Therefore, the folklore does not relate the Jomon event. ^<14>C dating and folklore of Mt. Ibuki area suggest that a landslide-dammed lake would occur repeatedly on Anegawa-river., 第19回名古屋大学年代測定総合研究センターシンポジウム平成18(2006)年度報告<第2部> Proceedings of the 19th symposiumon on Chronological Studies at the Nagoya University Center for Chronological Research\
