 note = {Recent excavation of wetland sites during the Jomon period in Japanese islands has revealed that the hunter-gatherers had a highly developed plant utilization system. The Shimo-yakebe site in Tokyo is one of the most important wetland sites during the Middle to Final Jo mon periods (ca. 5,300 -2,800 cal BP). Two mounds of walnuts (Juglans mandshurica) stones, five mounds of the horse chestnut (Aesculus turbinate) seeds, and wooden structures for water usage made of chestnut (Castanea crenαta) woods were found in and around sediments of the old river channel. These remains indicate multiple use of the plant recourses by hunter-gatherers at that time. Lacquered wooden artifacts, lacquered pottery, and rows of wooden stake including lacquer trees (Rhus verniciflua) indicate systematic usage and management of the trees around the settlement, 第21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20(2008)年度報告},
