Studies of the transitional phase from Jomon to Yayoi in the easten Japan

通过对绳纹陶器和弥生陶器的多槽表面处理Jokonn的研究，很有可能这种处理不是通常所接受的贝壳软体动物的产品，而是专门用于制作陶器的特征工具。实验重建结果与模拟物体的重建结果吻合较好。该工具有一个真正的梳状结构的小竹棒，不同于目前的固体板与牙齿，结合到一个木轴与对角斯特林。本工具的分类和名称如下：修整与未修整的牙齿，凸，凹和混合棒等。

Through the scrutiny into Jokonn, multi-grooved surface treatment, on the final Jomon and initial Yayoi pottery, it is highly probable that the treatment is not by the products of shell molluscus, as is commonly accepted, but by a characteristic tool for the making pottery exclusively. Experimental reconstruction is good accordance with those from enearthed objects. The tool has a genuine comb-like structure of small bamboo sticks, different from present of a solid plate with teeth, combined to a wooden axis with diagonal stling. Classification and designation of this tool are as follows : trimmed vs.untrimmed teeth, convex, concave and those mixed sticks and so on.
