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

正如我们所知，绳纹时代、弥生时代和古坟时代的陶器传统在每个分布区域都没有中断过。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，或者在少数情况下，搬到遥远的地区，遇到了已经存在于那里的陶器传统。我们称这些现象为“不同陶艺传统的相遇”。在某些情况下，入侵的传统赶走了土著传统，在其他情况下，两种传统融合为一。两种传统可能以马赛克的方式分布，或者在共同的定居点共存。这些不同的模式必然反映了承载各自传统的人类群体之间的新关系。在这个项目中，来自不同时期、不同地区的陶艺研究专家们聚集并拾取了许多“不同陶艺传统相遇”的案例。它们被分为几种模式，并对每种模式背后的关系进行了研究。绳纹、弥生等各个时期的主要特征模式被认为是各自基本社会结构的反映。对绳纹、弥生和古坟各个时期的基本陶器概念，如Keishiki、Yoshiki、Keito、Ruikei等进行了研究和整理。本项目对粘土材料进行了岩石学和化学研究。研究了环境变化与陶艺传统迁移的关系。2007年11月25日和26日在东京大学举行了一场公开报告会，参加报告会的人多达200人，显示出考古学家对这个项目的浓厚兴趣。最终报告书将于2008年由社社以普通书籍的形式出版。

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.
