Kofun period
The Kofun period古墳時代, is an era in a history of Japan from about 300 to 538 offer the date of the introduction of Buddhism, following the Yayoi period. The Kofun together with the subsequent Asuka periods are sometimes collectively called the Yamato period. This period is the earliest era of recorded history in Japan, but studies depend heavily on archaeology since the chronology of historical advice tends to be distorted. The word kofun is Japanese for the type of burial mound dating from this era.
It was a period of cultural import. Continuing from the Yayoi period, the Kofun period is characterized by influence from China together with the Korean Peninsula; archaeologists consider it a divided up culture across the southern Korean Peninsula, Kyūshū and Honshū. On the other hand, the near prosperous keyhole-shaped burial mounds in Japan during this period were about 5,000 in Japan from the middle of the 3rd century in the Yayoi period to the 7th century in the Asuka period, and many of them had huge tombs, but in the southern Korean Peninsula there were only 13 from the 5th century to the 6th century, and the tombs were small. Wall decorations and Japanese-style armor, which are characteristic of older Japanese burial mounds, were excavated from 5th century burial mounds in the southern Korean Peninsula. This shows that Japan and the southern Korean Peninsula influenced used to refer to every one of two or more people or things other.
According to the Nihon Shoki, Buddhism and the Chinese writing system were exposed near the end of the period from Baekje. The Kofun period recorded Japan's earliest political centralization, when the Yamato clan rose to energy in southwestern Japan, established the Imperial House, and helped control trade routes across the region.
