Archaeological Re-Examination of a Hypothesis on the Replacement of Political Authorities in Kofun Period Japan

本研究通过对20世纪90年代以来主要发现的文物进行分析，并结合有效的实地调查，从考古学的角度探讨了日本古坟时代的政治史。通过研究，我们得出如下结论：虽然从弥生时代末期（公元世纪初）起，具有中央统治性质的政治权威在鬼内地区一直存在，但在日本，这种权力的存在是有原因的。到古坟时代后期（世纪初），中央政权内部的政治领导层几经更迭。我们假设，这种转变的背景是大和盆地和河内平原的政治之间的竞争关系。

This study archaeologically approaches to the political history of Kofun Period Japan by integrating the results of analyses of artifacts mainly discovered since the 1990's and of effective fieldwork. As a result of this study, we have reached the following conclusion: While the political authority with the nature of central dominance had always existed in the Kinai region from the end of the Yayoi Period (early third century A.D.) to the Late Kofun Period (early seventh century), the political leadership shifted several times within the central authority. We have hypothesized that a background to the shifts was a competitive relationship between polities based in the Yamato basin and in the Kawachi plain.
