A study of the transformation process of the social atructure during Yayoi period as seen from settlement, cemetery, ritual and pottery.

本研究旨在从聚落墓地、仪式和陶器三个方面来阐释弥合时期社会结构的变迁过程，旨在揭示社会群体的组织原则、社会群体在结构中所反映的社会群体之间的关系以及陶艺风格的传播，以及群体仪式所体现出的成员共同的价值观。对这些现象在时间和空间上的轨迹进行了分析，并对分析结果进行了综合。我明确了整个社会结构的转变和社会群体之间政治和文化关系的变化阶段。我检查了对巨大的护城河和围堤居民点的估计，并重新审视了阿克堡、集中居住在城市、农民淡季分工和专职专家的概念。从陶艺风格的分布来看，分析了陶艺风格空间关系的时间轨迹，以及社会群体之间关系的变迁。笔者将这一分析结果与社会群体组织原则的变迁相结合，得出了阐释社会整体结构的变迁，以及社会群体之间政治文化关系的变化方面的观点。弥合后期至清末，社会变迁、多个地区的分层与政治整合、礼仪制度的变迁，从根本上阐明了弥合社会作为早期农业社会稳定至弥合末期以来社会变迁的内外部因素，阐明了造成这一现象的原因。

The purpose of this study is to elucidate the transformation process of the social structure during Yayoi period as seen from settlement cemetery, ritual and pottery.I aimed at the organization principles of social groups, the relationships between social groups reflected in the structure and the diffusion of pottery styles, and values which were holded in common of members reflected in the communal rites. I analyzed the trajectory of these phenomenon in time and space and integrated the results of the analysis. I made clear the transformation of the whole social structure and the changing phase of political and cultural relationships between social groups.I examined the estimation of huge moated and embanked settlements, and re-examined the concepts of ackerburgerstadt, concentrated dwelling into the city, division of labor during farmers slack season, full time specialists. I concluded the unsuitableness of the concept of Yayoi city.I analyzed the time trajectory of spatial relationships between pottery styles, and transition of relationships between social groups as seen from distributions of pottery styles. I synthesized the results of this analysis with the transformation of organization principles of social groups, and obtained the perspectives to elucidate the transformations of whole structures of the society, and changing aspects of relationships between political and cultural between social groups.During the late Yayoi period and the beginning of Kofun period, social changes, stratification and political integration of many districts, and transformations of ritual rates, advanced radicallyI elucidated the reason of this phenomenon by means of making clear both external and internal factors of social changes since the stabilization of Yayoi society as the early agricultural society to the end of Yayoi period.
