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.
