๐ฏ๐ต Genetic Landscape of Japan
Japan is one of the most genetically homogeneous major nations, with over 98% of the population sharing Yamato Japanese ancestry. Two ancient groups โ Jลmon (indigenous hunter-gatherers) and Yayoi (rice farmers from mainland Asia) โ merged to form modern Japanese. The Ainu people of Hokkaido carry distinct genetic markers including wavy hair and more body hair. Okinawans have their own unique genetic profile closer to ancient Jลmon. Blood type is culturally significant in Japan โ "blood type personality" is widely discussed in media and dating. A+ blood type is most common, unlike the global O+ dominance.
