The foreign relations of Wakasa district in the Kofun period

在古日本的古坟时代，沿海沿着的许多地区都与大陆和边远地区有着外交关系。若狭区是第5、6届活动最具代表性的地区。在向海山1号墓中引入的最古老的带侧门的墓室。它是25年前在那里被挖掘出来的。但目前还不清楚古墓及其遗骸的细节。因此，本研究的主要目的是通过对出土文献和出土文物的研究，厘清它们之间的关系，恢复地方关系，从而确定墓葬物品的放置方式，并揭示大量的铁兵器和其他物品的信息，证明墓葬和地区的价值。并对若狭地区的其他几座古坟进行了测量和部分发掘，以重建古坟时期的政治运动，发现该地区对古代日本中央政府的重要性。

In the Kofun period of ancient Japan, many districts along the sea coast had foreign relationships with the continent and the remote areas. Wakasa district was the most typical area in the 5th and 6th to demonstrate the activities. The oldest chamber with a lateral entrance introduced at the Mukaiyama No.1 tumulus. It was excavated there more than 25 years ago. But no details are known about the tumulus and its remains. So the purpose of this study is mainly to clarify them and restore the local relationship by researching the excavation documents and findings.In consequent, unknown setting ways of burial goods were identified and much information about iron armaments and other goods were revealed demonstrating the value of the tumulus and the district. And I measured and partially excavated at other several tumuli in Wakasa district to rebuild the political movements during the Kofun period and found how this district were important for the central government in ancient Japan.
