日本列岛从北部的北海道到南部的琉球群岛，绵延约 3,000 公里，至少从 3 万年前开始就有人类活动 (KYA)。 16 至 3 KYA 的绳文时代与绳纹陶器有关，当时的人们是狩猎采集者，占据了日本列岛的一系列地区。弥生时代从 3 KYA 到 1.7 KYA 见证了来自亚洲大陆的移民的引入，他们将水稻农业带到了群岛。基于颅面测量的双结构模型提出，绳文人和弥生人的混合导致了当今的日本人。随后在当今和古代人类样本中使用单亲和常染色体标记进行的遗传学研究广泛支持双结构模型。这些遗传数据还揭示了土著阿伊努人和琉球人的独特性，同时进一步展示了日本本土的遗传亚结构。
The Japanese Archipelago stretches approximately 3,000 kilometers from Hokkaido in the north to the Ryukyu Islands in the south, and has seen human activity since at least 30 thousand years ago (KYA). The Jomon period from 16 to 3 KYA is associated with cord-marked pottery and the people at that time, who were hunter-gatherers, occupied a range of locations across the Japanese Archipelago. The Yayoi period from 3 to 1.7 KYA saw the introduction of migrants from the Asian Continent who brought rice agriculture to the archipelago. The dual-structure model, which is based on craniofacial measurements, proposes that admixture between the Jomon and Yayoi people resulted in current-day Japanese. Subsequent genetic studies using uniparental and autosomal markers in current-day and ancient human samples are widely in support of the dual-structure model. These genetic data have also unveiled the uniqueness of the indigenous Ainu and Ryukyuan people while further demonstrating the genetic substructure within the Mainland Japanese.
