The objectives of this research were as follows:a) to examine the nature ofpossible dating material-caused discrepancies in the outcomes of the AMS dating of different types of dating materials, particularly soot adhering to the surface of pots, charred seeds and human bones;andb) to compare the outcomes of the AMS dating of different types of dating materials with some absolute dates of the Middle and Late Yayoi periods determined by the TPQ (i. e., Terminus Post Quem) of imported absolute-datable artifacts (e. g. Han Bronze mirrors) from Mainland Asia and the Korean peninsulaThe notable outcomes are as follows:1) From a rigorous cross-checking of contemporaneity between individual chronological stages by examining same types of pots excavated from the both regions, the relative chronological stages of the northern Kyushu and Setouchi-Kansai regions are roughly contemporaneous stage by stage, except the transitional stages from the Middle to the Late Yayoi where the first stage of the Late Yayoi period of the Setouchi-Kansai region began sometime during the later half of the first half of the Late Yayoi of the northern Kyushu region.2) The TPQ of the artifacts excavated from burial jars dated to the second half of the first half of the Late Yayoi of the northern Kyushu region has been determined to date from AD 50~AD 75, and this poses a serious question to the validity of the widely accepted date for the beginning of the Late Yayoi of the Setouchi-Kansai region to be around 1 AD.3) The outcomes of the AMS dating of charred seeds show considerably earlier dates than what are determined from the TPQ of the imported artifacts from Mainland Asia. The date of the second half of the first half of the Late Yayoi of the northern Kyushu region, as mentioned, dates from AD 50~AD 75, whereas the dates obtained from the charred seeds are around 1AD. This makes further researches into possible discrepancies caused by different dating materials of absolute necessity.

本研究的目的是：（1）探讨不同类型的测年材料，特别是附着在陶罐表面的煤烟、烧焦的种子和人骨的AMS测年结果之间可能存在的差异的性质;（2）将不同类型测年材料的AMS测年结果与TPQ测定的弥生时代中晚期的一些绝对年龄进行比较（即：（1）将不同类型测年材料的AMS测年结果与TPQ测定的弥生时代中晚期的一些绝对年龄进行比较。例如，Terminus Post Quem）的绝对数据化工件（例如。G.汉铜镜），主要成果如下：1）通过对两个地区出土的同类陶罐进行严格的年代学对比，可以看出，北方九州地区和濑户内关西地区的相对年代学阶段大致是一个阶段一个阶段地同时发生的，除了从弥生中期到弥生晚期的过渡阶段，即濑户内-关西地区的弥生晚期第一阶段开始于北方九州地区的弥生晚期上半期的后半期。2）从北方九州地区弥生晚期上半期后半期的墓葬罐中出土的文物的TPQ被确定为公元50~公元75年，这对广泛接受的Setouchi-Kansai地区晚弥生时代开始于公元1年左右的有效性提出了严重的问题。AMS测年的结果烧焦的种子显示相当早的日期比从亚洲大陆进口文物的TPQ确定。如前所述，北方九州地区的晚弥生的前半部分的后半部分的日期为公元50~公元75年，而从烧焦的种子中获得的日期约为公元1年。这使得进一步研究不同年代材料可能造成的差异是绝对必要的。
