Who Are The Japanese?

And where did they come from?

The answers are difficult to come by, though not impossible ― the real problem is that the Japanese themselves may not want to know. Unearthing the origins of the Japanese is a much harder task than you might guess. Among world powers today, the Japanese are the most distinctive in their culture and environment. The origins of their language are one of the most disputed questions of linguistics. These questions are central to the self-image of the Japanese and to how they are viewed by other peoples. Japan's rising dominance and touchy relations with its neighbors make it more important than ever to strip away myths and find answers.

The search for answers is difficult because the evidence is so conflicting. On the one hand, the Japanese people are biologically undistinctive, being very similar in appearance and genes to other East Asians, especially to Koreans. As the Japanese like to stress, they are culturally and biologically rather homogeneous, with the exception of a distinctive people called the Ainu on Japan's northernmost island of Hokkaido. Taken together, these facts seem to suggest that the Japanese reached Japan only recently from the Asian mainland, too recently to have evolved differences from their mainland cousins, and displaced the Ainu, who represent the original inhabitants. But if that were true, you might expect the Japanese language to show close affinities to some mainland language, just as English is obviously closely related to other Germanic languages (because Anglo-Saxons from the continent conquered England as recently as the sixth century A.D.). How can we resolve this contradiction between Japan's presumably ancient language and the evidence for recent origins?
