Ancestry profile of Japanese genetic clusters illustrating their genetic similarities to five mainland Asian populations. Gyaneshwer Chaubey and George van Driem (2020) suggest that the Jōmon people were rather heterogeneous, and that there was also a pre-Yayoi migration during the Jōmon period, which may be linked to the arrival of the Japonic languages, meaning that Japonic is one of the ...
The style of pottery created by the Jōmon people is identifiable for its "cord-marked" patterns, hence the name "Jōmon" (縄文, "straw rope pattern").The pottery styles characteristic of the first phases of Jōmon culture used decoration created by impressing cords into the surface of wet clay, and are generally accepted to be among the oldest forms of pottery in East Asia and the world.

The relationship of Jōmon people to the modern Japanese (Yamato people), Ryukyuans, and Ainu is not clear. Morphological studies of dental variation and genetic studies suggest that the Jōmon people were rather diverse, and mitochondrial DNA studies indicate the Jōmon people were closely related to modern-day East Asians.
In comparison to modern populations, the Sanganji Jomon individuals are closest to modern Japanese, showing strongest genetic affinity for the Ainu people, followed by the Ryukyuan people. From this study, researchers estimate that the modern Japanese population inherited less than 20% of their DNA from the ancient Jomon populations. [3]
However, recent DNA analyses revealed genetic links to both Jomon and Japanese people, as well as to the broader East Asian population cluster. The Minatogawa specimens' genetic type, based on extracted DNA alleles, was found to be common among modern Japanese peoples, Jomon and Yayoi samples, although being not their direct ancestor.
Haplogroup migration within East Asia. Haplogroup C-M8 also known as Haplogroup C1a1 is a Y-chromosome haplogroup.It is one of two branches of Haplogroup C1a, one of the descendants of Haplogroup C-M130.
According to the recent genetic studies, the Ryukyuans share more alleles with the southern Jōmon (16,000–3,000 years ago) hunter-gatherers than the Yayoi people, who had rice farming culture, have smaller genetic contributions from Asian continental populations, which supports the dual-structure model of K. Hanihara (1991), a widely ...
The term "Japanese people" or even "Japanese-Japanese" are often used instead. [16] Genetic and anthropological studies indicate that the Ryukyuans are significantly related to the Ainu people and share the ancestry with the indigenous prehistoric Jōmon period (pre 10,000–1,000 BCE) people, who arrived from Southeast Asia and with the Yamato ...
