Findings by American anthropologist C. Loring Brace, University of Michigan, will surely be controversial in race conscious Japan. The eye of the predicted storm will be the Ainu, a "racially different" group of some 18,000 people now living on the northern island of Hokkaido. Pure-blooded Ainu are easy to spot: they have lighter skin, more body hair, and higher-bridged noses than most Japanese. Most Japanese tend to look down on the Ainu.
Brace has studied the skeletons of about 1,100 Japanese, Ainu, and other Asian ethnic groups and has concluded that the revered samurai of Japan are actually descendants of the Ainu, not of the Yayoi from whom most modern Japanese are descended. In fact, Brace threw more fuel on the fire with:
"Dr. Brace said this interpretation also explains why the facial features of the Japanese ruling class are so often unlike those of typical modern Japanese. The Ainu-related samurai achieved such power and prestige in medieval Japan that they intermarried with royality and nobility, passing on Jomon-Ainu blood in the upper classes, while other Japanese were primarily descended from the Yoyoi." The reactions of Japanese scientists have been muted so. One Japanese anthropologist did say to Brace," I hope you are wrong."
The Ainu and their origin have always been rather mysterious, with some people claiming that the Ainu are really Caucasian or proto-Caucasian - in other words, "white." At present, Brace's study denies this interpretation.
Japan was settled by two groups of Mongolians: The shorter darker ones from Southern China were conquered by the taller lighter colored ones from Northern Asia (related to Koreans, manchus, Mongols). That is why there is a difference.
Thank you, blam. I was hoping someone more eloquent than I would chime in with more info. Our family impression matches here. We thought that the Ainu were somewhat looked down upon.
