A subclade of Haplogroup O2b, namely Haplogroup O2b1-47z, is found with high frequency among the Yamato people and Ryukyuan populations of Japan.
Haplogroup O2b1 has been detected in approximately 22% of all males who speak a Japonic language, while it has not been found at all among a total of twenty Ainu males whose Y-DNA has been sampled in two genetic studies.[8][19] Based on the STR haplotype diversity within Haplogroup O2b1,
it has been estimated that this haplogroup began to experience a population expansion among the proto-Japanese of approximately 4,000 years ago, which makes it a good candidate for a marker of the intrusion of a Neolithic population of the prehistoric Korean Peninsula into the southwestern parts of the Japanese Archipelago.

However, the parent haplogroup, O2b*, is also found among Japanese, although at a relatively low frequency of approximately 4%[14] to 8%[9], and the descendant haplogroup O2b1 is found only with low frequency among samples of modern Koreans,

which suggests the possibility that Haplogroup O2b* might have colonized the Japanese Archipelago much earlier, with the subgroup O2b1 subsequently evolving within the proto-Japanese-Ryukyuan population of the western parts of the archipelago.
