彌生時代
The were an ancient ethnic group that migrated to the Japanese archipelago from China and Korea during the Yayoi period (300 BCE–300 CE). Radio-carbon evidence suggests the Yayoi period began between 1,000 and 800 BCE. They interacted, killed off, and mixed with the remaining Jōmon people to form the modern Japanese people. Modern Japanese people have primarily Yayoi ancestry (about 90% on average, with their remaining ancestry deriving from the Jōmon).
