I am talking about BC time. By 1300, everybody in Asia and Europe knew where everybody was plus trade required technology. I would guess the Japanese would have gone north to the Aleutians and worked their way down. However the books I have read on that, claims they were Chinese and not Japanese. They could have even been Koreans since they could sail from Korea to Japan at that time.

The problem is that literacy did not arrive in Japan until the 500s.

At the same time DNA evidence demonstrates that 40% of the genetic background of the modern Japanese derives from the original inhabitants known as Jomon (and today as Ainu).

Old Billybob out there in Oregon ~ Kenniwick Man ~ is pretty much identical to a Jomon.

The Japanese living in a land of islands and having boat technology could probably have gone anywhere they wished ~ I think there's this find in Chile that suggests Jomon made it there.

A later arrival from China are the Hakka people. Outside of the Koreans, they provide that other 60% of the DNA to the Japanese. They absorbed boat technology on their arrival in Manchuria before traveling on to japan. I think they are also called the Ya Yoi people when studying their settlement of Japan.
