In January 1964, writers found two stone-tools from the Kwanto loam in the neighbourhood of Yamagata-machi, Naka-gun Ibaraki Prefecture. Its geological horizon probably correlated to the Musashino loam in the Southern Kwanto District. And the stone-tools are made from siliceous shale belonging to the Miocene formation in these district. The one of them is core hand-axe, and the other is core scraper, both of which are worked with modern technique to make flakes and microliths.
