爪形文土器段階における石材運用 －野国タイプ型石斧の再定義と評価を中心に－

In the paper I study stone tool industries in the phase of the Tsumegatamon-style pottery. It has been considered that these assemblage has a distinctive characteristic that is different from the counterparts in other periods. Especially, edge-polished stone adze in the assemblages shows characteristic designs and distinctive manufacturing technique. Then I tentatively define it as the "Noguni-type stone adze".
　In this phase, these was a variety of the assemblages in the light of presence and absence of the Noguni-type stone adze and chart materials. This implies that the people used a variety of localities for procuring raw stone materials. The industries in the phase of the Tsumegatamon style pottery were characterized by the distinctive ways of procuring and reduction of stone materials. Because of the peculiarities in the industries during this period, I tentaivety define it as the "Pre-Ryukyu Jomon style industry", and point out the possibility that this tradition was not succeeded by the following "Ryukyu Jomon style industries".
