Jōmon people

Jōmon people (縄文 人, Jōmon jin) is the generic name of the indigenous hunter-gatherer population that lived in the Japanese archipelago during the Jōmon period (c. 14,000 to 300 BC). They were united through a common Jōmon culture, which reached a considerable degree of sedentism and cultural complexity.

The Jōmon people are characterized by a deeply diverged East Asian ancestry and contributed around 5-15% ancestry to modern Japanese people. Population genomic data from multiple Jōmon period remains suggest that they diverged from "Ancestral East Asians" prior to the divergence of Northern and Southern East Asians, sometime between 30,000 to 20,000 years ago, but after the divergence of "Basal East Asian" Tianyuan and Hoabinhian lineages. After their migration into the Japanese archipelago, they became largely isolated from outside geneflow at c. 15,000 to 20,000 BC.
