Yamato Kingship
The was a tribal alliance centered on the Yamato region (Nara Prefecture) from the 4th century to the 7th century, and ruled over the alliance of noble families in the central and western parts of the Japanese archipelago. The age is from the 4th to the 7th century, later than the Yamatai Kingdom. After the Taika Reform, the ōkimi as an emperor, at that time, was in power, and the Yamato period ended. The time period is archaeologically known as the Kofun period. Regarding its establishment, due to the relationship between Yamatai and Yamato's succession to the king's power, there are very different views on it. The Yamato Kingship refers to the regime that emerged in the Nara region (Yamato region) since the 4th century. But the term does not imply the origin of Japan, which is disputed in Japanese history. At the same time as the rise of the , there were probably several or even dozens of power centers in the Japanese archipelago. This is an issue that Japanese academia attaches great importance to. In the course of the development of the tribes from the state of separation to the direction of union between the 2nd and 3rd centuries, the Japanese royal power had become the center of the tribes. In order to establish its position as a united ally, the Japanese royal power attached importance to foreign relations, paid tribute to the Eastern Jin Dynasty and the Southern Song Dynasty, and made every effort to maintain close relations with the countries on the Korean peninsula (Baekje and Gaya), monopolizing various technologies imported by foreigners. In the second half of the 5th century, it was able to overwhelm the gentry in the capital and the local clans. Name Until the early 1970s, the "" was widely used as a time period from the 4th to the 6th century, and the name "" was used unambiguously as the political power that ruled the main part of the Japanese archipelago during that period. However, since the 1970s, with the discovery of significant kofuns and excavations, the use of physical and chemical dating and dendrochronology became available. As the accuracy of these methods improved, research on the chronology of kofun tombs progressed remarkably, and the view that it was not necessarily appropriate to use the words "Yamato" and "imperial court" to describe the period emerged, and this view became influential in historical societies in Japan, and thus the term "Yamato period" was replaced by "Kofun period" instead of "Yamato period" has become a common name in Japanese historical research and higher education in Japan. However, dendrochronology and radiocarbon dating have not yet reached a stage where they can actually be called established techniques, and many researchers have pointed out shortcomings and problems with their accuracy and measurement methods of the Kofun period.。 In this article, these "" and "" will be explained. In the first half of the Kofun period, terms such as "," "," and "" have also been used
