>>13725533No, you read that on 4chan. It's Jomon first of all, and there is no proof of this intermingling. The original way of saying Japanese wasn't a pure race was to say Koreans crossed a land bridge. This was proven factually impossible by geology and DNA advancements which showed Japanese have unique DNA. Now the bullshit rhetoric spread online is that Yayoi intermingled, which is not backed up by any evidence. Yayoi was a period of time declared as Yayoi long before any of these bullshit theories, and Jomon is also an era. There are different kinds of Japanese depending in what are they live, nobody intermingled with a completely foreign culture with a different language to any considerable degree. Millions did not just get on boats and come all at once then stop for 1500 years. In 300BC no surrounding country had large-scale boats for that, most countries didn't have boats at all besides small paddle craft.
Now stop spreading lies you just randomly believed from 4chan.
