On the process of acceptance of Zenpokoenfun(Keyhole-shaped tumuli) in San-in District, Japan

在不丹寺古墓的考古调查结果作出了相当大的贡献，研究的过程中接受善宝园分（钥匙孔形古墓）在山阴。我们6年的调查显示，Fudanji古墓是最早的Zenpokohofun之一，钥匙孔形的古墓，后面是一个四边形，在山阴。由于破坏性的抢劫，墓葬本身和随葬品全部丢失。但是，墓葬的建造技术是很好的观察。除此之外，我还观察并记录了从To t到ri pref的几个早期Kofun时期古墓中的随葬品。

The results of archaeological investigations at Fudanji tumulus have made considerable contribution to research into the process of acceptance of Zenpokoenfun(keyhole-shaped tumuli) in San-in. Our 6-years investigation reveals that the Fudanji tumulus is one of the earliest Zenpokohofun, keyhole-shaped tumuli with a quadrangular rear potion, in San-in. Because of destructive robbing, the burial itself and funerary objects were totally lost. But, the construction skill of burial mound was well observed. Other than that above, I observed and recorded funerary objects from several early Kofun-period tumuli in To t to r i pref.
