Encounters among different pottery traditions : migration, habitation, relation, and the societies behind the phenomena

正如我们所知，在绳纹时期、弥生时期和古方时期，陶器的传统在每个分配区域都没有中断地发生变化。然而，他们并不总是固守自己原来的地区，有时会搬到邻近的地区，有时也会搬到很远的地方，遇到那里存在的陶器传统。我们把这些现象称为“不同陶器传统之间的相遇”。这种现象是多种多样的，有时入侵的传统赶走了本土传统，有时两种传统融为一体。两种传统可能以镶嵌方式分布，也可能在共同的聚落中共存。这些不同的图案必然反映了人类群体之间遇到的承袭各自传统的新关系。在这个项目中，来自多个时期和领域的陶器研究专家聚集在一起，挑选了许多案例，这些案例都是“不同陶器传统的相遇”。将其划分为几种纹样，并考察了每一纹样背后的关系，认为每一时期的主要特征纹样如绳纹、弥合等反映了各自的基本社会结构，考察并整理了绳纹、弥合、高芬等各个时期的基本陶艺概念，如圭基、吉木、圭藤、瑞凯等。为实现该项目的目标，对粘土材料的岩石学和化学研究进行了尝试。2007年11月25日和26日在东京大学举行了一次公开报告会，与会人员多达200人，显示出考古学家对这一项目的浓厚兴趣。该项目的最终报告将于2008年由Doseisha出版，以普通书的形式在书店找到。

As we know for the Jomon, Yayoi, and Kofun periods, pottery traditions changed without break in each distributional area. However, they did not always cling to their own original areas but sometimes moved into neighboring or, in a few cases, far away areas and encountered the pottery tradition which had existed there. We call these phenomena "encounters among different pottery traditions" The phenomena are various ; in some cases the invading tradition drives away the indigenous one and in other cases the two traditions merge into one. Two traditions may distribute in a mosaic manner, or coexist in the common settlements. These various patterns must reflect new relations among human groups which have encountered carrying each own tradition.In this project, experts of pottery research specializing in many periods and areas gathered and picked up many cases of "encounters among different pottery traditions". They were classified into several patterns and the relations behind each pattern were examined.Characteristic pattern seen dominantly in each period such as Jomon or Yayoi was recognized as a reflection of respective basic social structure.Basic pottery concepts such as Keishiki, Yoshiki, Keito, Ruikei, etc. beyond each period of the Jomon, Yayoi, and Kofun were examined and put in order. Petrological and chemical researches of clay material were tried for the aim of this project. Relation between environmental changes and translocation of pottery traditions was examined also.A public report meeting was held at The University of Tokyo on November 25^<th> and 26^<th>, 2007 and the attendants coming up to two hundreds demonstrated archaeologists' keen interest in this project. The final report on the project will be published by Doseisha in 2008 in a form of normal book found at bookstores.
