The Ryukyu Islands stretch from southern Japan towards Taiwan, with Okinawa as the largest island. Their languages belong to the Japonic family but are distinct from Japanese, and the islands formed an independent kingdom from the 15th century until their annexation by Japan in 1879. Genetic studies have found that Ryukyuans carry more ancestry from the Jomon, the ancient hunter-gatherers of the Japanese islands, than mainland Japanese. Our model has no Jomon reference: the Ryukyuan average is 81.2% East Asian, 10.4% Ancient Northeast Asian and 8.3% South Asian hunter-gatherer related, a share that may partly stand in for that old island ancestry. The sample behind this average is low resolution, which helps explain why even the nearest modern averages, Han Chinese from Shanxi (0.0463) and Koreans from Jeju Island (0.0495), are only moderately close. The closest ancient groups are Three Kingdoms-period Koreans from Yuha-ri (0.0453) and Late Dawenkou Neolithic people from Shandong.

Ryukyuan (Okinawan) is one of the 335 modern populations in our population genetics atlas. The numbers on this page describe the average Global25 (G25) genome of the Ryukyuan (Okinawan) individuals sampled in Japan (Okinawa), listed in the G25 sheet as "Ryukyuan_(low_res)". Like every population average, it smooths over a lot of variation between individuals.

Modelled as a mix of deep ancestral reference populations, the Ryukyuan (Okinawan) average comes out as 81.2% East Asian, 10.4% Ancient Northeast Asians and 8.3% South Asian hunter-gatherer related (Irula proxy). The East Asian component reflects ancestry most common today in East Asia. With well over half of the total, this single source dominates the profile.

The fit is acceptable (fit distance 0.039): treat the proportions as a good approximation rather than exact values. This population was modelled with a global set of reference populations (ancient genomes, plus modern stand-ins where no suitable ancient genome exists), because West Eurasian sources alone cannot describe it.

Closest modern populations to Ryukyuan (Okinawan)

Ranking every modern population by genetic distance puts Han (Shanxi Xinzhou) first for Ryukyuan (Okinawan), at 0.046, then Han (Shanxi Shuozhou) and Korean (Jeju Island). By the tenth closest (Korean (Yanbian Antu)) the distance grows to 0.056, a common pattern for a population that shares ancestry with its neighbours while keeping a profile of its own.

Distances are Euclidean distances between averaged G25 coordinates. On our scale, below 0.025 is very close, below 0.050 close, below 0.080 moderate, and beyond that distant.

Closest ancient populations to Ryukyuan (Okinawan)

Among ancient genomes, the closest match to the modern Ryukyuan (Okinawan) average is Korea Three Kingdoms Yuha-ri (Three Kingdoms period, c. 57 BC-668 AD), at 0.045, followed by China Shandong N Late Dawenkou Jiaojia and China Shandong N Late Dawenkou Gangshang. That is a close match: much of the modern profile was already present then, while later movements of people added further layers. A close ancient match is not proof of direct descent: it means those individuals carried a similar overall mix of ancestry.

Ancient DNA from Japan

Our ancient DNA database holds 177 individuals excavated in present-day Japan, dated from about 17,950 BC to 1808 AD. The most frequent Y-DNA haplogroups among them are D1a (10), O1b (3) and B (1), and the most frequent mtDNA haplogroups are N9 (75), M7 (29) and G1 (16). These are people who lived on the same land in the past, not necessarily ancestors of today's Ryukyuan (Okinawan) population.

About these numbers

A word of caution: these figures describe the average of the Ryukyuan (Okinawan) individuals who were sampled, not every person who identifies as Ryukyuan (Okinawan). Individuals vary around that average, and identity is about history, language and family, not about a genetic score. Read this page as a map of deep ancestry, not as a definition.

Method: averaged G25 coordinates, Euclidean distances to other modern and ancient averages, and a non-negative least-squares model against deep ancestral reference populations (data generated 2026-10-01). Read the full method.
