The basic study about the ritual and social organization of the society at the Yayoi period based on the analysis and corpus of the date of the figurines.

通过三年的工作，我已经捕捉到了弥生时代雕像的274个日期。我把这些日期放在一起，作为追随者，我得到了三个重要的结果。这些日期已输入计算机。参考书的日期也被输入。(3)绘制并编辑了由这些材料组成的36个图形。笔者在此基础上对弥生社会的仪式特征和社会组织进行了推测，并结合绳纹时期的土狗俑与弥生时期中国和日本使用同一时期的一些材料进行了对比分析。
