History of JapanThe first human inhabitants of the Japanese archipelago have been traced to the Paleolithic, around 38-40,000 years ago. The Jōmon period, named after its cord-marked pottery, was followed by the Yayoi period in the first millennium BC when new inventions were introduced from Asia. During this period, the first known written reference to Japan was recorded in the Chinese Book of Han in the first century AD. Around the 3rd century BC, the Yayoi people from the continent immigrated to the Japanese archipelago and introduced iron technology and agricultural civilization.
Kofun periodThe Kofun period is an era in the history of Japan from about 300 to 538 AD (the date of the introduction of Buddhism), following the Yayoi period. The Kofun and 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 sources 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.
Asuka periodThe Asuka period was a period in the history of Japan lasting from 592 to 710 (or 593 to 710), although its beginning could be said to overlap with the preceding Kofun period. The Yamato polity evolved greatly during the Asuka period, which is named after the Asuka region, about south of the modern city of Nara. The Asuka period is characterized by its significant artistic, social, and political transformations, having their origins in the late Kofun period. The introduction of Buddhism marked a change in Japanese society.
Nakatomi clanwas a Japanese aristocratic kin group (uji). The clan claims descent from Amenokoyane. The Nakatomi was an influential clan in Classical Japan. Along with the Inbe clan, the Nakatomi were one of the two clans that oversaw certain important national rites, and one of many to claim descent from divine clan ancestors "only a degree less sublime than the imperial ancestors". It is said that soon after the beginning of Jimmu's reign, a Master of Ceremonies (saishu) was appointed; and this office was commonly held by a member of the Nakatomi clan after the 8th century.
