Modern Japanese have two major ancestral populations: the indigenous Jomon people and immigrants from continental East Asia. To figure out the population history in Japanese archipelago, we developed a reference-free detection method of genetic components from ancestral populations using a summary statistic, the ancestry-marker index (AMI). We applied the AMI to modern Japanese samples and identified 208,648 SNPs that were likely derived from the Jomon people (Jomon-derived SNPs). The analysis… 

Figures and Tables from this paper


Unique characteristics of the Ainu population in Northern Japan
It is found that the Ainu are genetically different from Mainland Japanese living in Tohoku, the northern part of Honshu Island, and estimated haplotypes of some Ainu individuals suggested relatively long-term admixture with MainlandJapanese.
Prefecture-level population structure of the Japanese based on SNP genotypes of 11,069 individuals.
Genome-wide single-nucleotide polymorphism data of 11,069 Japanese individuals recruited from all 47 prefectures of Japan revealed that mainland Japanese were not genetically homogeneous, and the genetic structure could be explained mainly by the degree of Jomon ancestry and the geographical location.
Analysis of whole Y-chromosome sequences reveals the Japanese population history in the Jomon period
The colder climate in the Late to Final Jomon period may have resulted in critical shortages of food for the Jomon people, who were hunter-gatherers, and the rice farming introduced by Yayoi immigrants may have helped the population size of theJomon people to recover.
The history of human populations in the Japanese Archipelago inferred from genome-wide SNP data with a special reference to the Ainu and the Ryukyuan populations
Close to one million single-nucleotide polymorphisms for the Ainu and the Ryukyuan are determined, and the dual structure model on the Japanese Archipelago populations clearly support, though the origins of the Jomon and the Yayoi people still remain to be solved.
A partial nuclear genome of the Jomons who lived 3000 years ago in Fukushima, Japan
The findings, based on the first analysis of Jomon nuclear genome sequence data, firmly demonstrate that the modern mainland Japanese resulted from genetic admixture of the indigenous Jomon people and later migrants.
Genomic Insights into the Formation of Human Populations in East Asia
The deep population history of East Asia remains poorly understood due to a lack of ancient DNA data and sparse sampling of present-day people1,2. We report genome-wide data from 166 East Asians
Ancient Admixture in Human History
A suite of methods for learning about population mixtures are presented, implemented in a software package called ADMIXTOOLS, that support formal tests for whether mixture occurred and make it possible to infer proportions and dates of mixture.
Allele frequencies of the ABCC11 gene for earwax phenotypes among ancient populations of Hokkaido, Japan
Results suggest that gene flow from the Northeastern Asian Continent to descendants of the Jomon/Epi-Jomon people of Hokkaido through the Okhotsk people occurred, resulting in the establishment of the Ainu.
Model-based verification of hypotheses on the origin of modern Japanese revisited by Bayesian inference based on genome-wide SNP data.
Three demographic models are compared by approximate Bayesian computation using genome-wide single nucleotide polymorphism (gwSNP) data from the Ainu people who are thought to be direct descendants of indigenous Jomon to provide a detailed picture of the complex hybridization model for Japanese population history.
