The foreign relations of Wakasa district in the Kofun period

在古坟时代，许多沿海地区都与大陆和偏远地区有外交关系。若坂地区是5日和6日最典型的示范地区。最古老的墓室，在Mukaiyama 1号墓室引入了一个侧向入口。它是在25年前被挖掘出来的。但关于古墓及其遗迹的细节尚不清楚。因此，本研究的目的主要是通过对发掘文献和发现的研究来厘清它们，恢复它们之间的地方关系。由此，发现了埋藏物品的未知设置方式，揭示了许多关于铁器武器和其他物品的信息，证明了古墓和该地区的价值。我测量并部分挖掘了若坂地区的其他几个古墓来重建古坟时期的政治运动发现这个地区对古代日本的中央政府有多么重要。

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.
