The Kasuga-Nanokaichi Site and Itai-Teragatani Site are located in the western district of Tanba, Hyogo Prefecture. We excavated these site from 1984 to 1985, identified the Aira-Tn ash(AT) and constructed an accurate chronology of the artifact assemblages. We found useful data for reconstructing the structure of paleolithic settlements.At the Kasuga-Nanokaichi Site, we excavated about 5, 000 artifacts, which could be divided into more than 20 clusters, three stone clusters and some stone heaps under the AT. These are divisible into at least two cultural layers. The main material of the artifacts is chert; sanukite [andesite] is occasionally found. We consider these assemblages to be one of the Paleolithic traditions in the Chugoku mountains.At the Itai-Teragatani site, AT is divided into two cultural layers. We excavated 11 areas of construction of stone implements, 6 pits, 5 clusters of charcoals, many stone heaps and many stone clusters on the lower layer. We found 2 types of techniques for fabricating stone implements in the two areas. We consider this evidence that the Paleolithic traditions in the Chugoku mountains and the Setouchi region were in contact.
