So, Ainu could get to the Isthmus that way, but so could the far more numerous, and still extant, plain old Chinese type Japanese found along the costs of El Salvador and Costa Rica.
Odds are good that all the West Coast native groups are overwhelmingly of Japanese origin.
However, trust me, I know an enormous number of Japanese and this dude is definitely Africanized ~ just like Obama. Doesn't mean the artist who made the amulets wasn't of Japanese origin, but it's not a self-portrait.
yeah yeah yeah
but back then, the ainu were the dominant people percentage wise.
side note: why does the word “ainu” mean dog in modern japanese?
