序言用C~(14)和考古学的方法来推定绳纹、弥生时代各时期的实际年代都在继续进行。C~(14)测定年代产生了对弥生各时期年代的新数值,但其本身也存在重新评价的问题。目前,在没有断代标准器物的时候,考古学的方法还没有一种更有效的手段。本文使用一些与弥生时代相关联,又有争议的考古资料来推断弥生时代的各年代,并探讨这种依据的准确程度。 The preamble uses C ~ (14) and archeological methods to estimate the jomon, and the actual years of each Yayoi period are continuing.

This article uses some archaeological data related to Yayoi times and controversial to infer the ages of the Yayoi period and to explore the accuracy of this basis.
