Note: Around here we have more than our fair share of people from El Salvador. They come in two varieties ~ white folks and Japanese. No other way to 'splain it.
Recently National Geo had a piece of some anomalous burials further up the coast in Costa Rica. They were pretty clearly Japanese graves.
It's time for another Kon Tiki where someone gets on a boat and drifts around the Pacific littoral until it stops in Latin America.
Regarding OTHER Japanese language uses in Souvrn' Mesco ~ the dominant tribe in El Salvador has a well preserved and researched language so you can go on line and dig it up. I don't think they teach it yet but that's coming.
As you know Japanese has more than one way to count things, people, events. It's rather complex, but one of the ways generates words that fit well within the phonemes of the way that Indian tribe "counts". There's a change (always expected) but it's a consistent change.
Now, Shang Dynasty stuff, back before the Internet I went down to a Smithsonian exhibit of Shang Dynasty characters. I took my handy dandy book that had a chapter about Indian sign language with me. It really hit the spot. I was there in a gathering of older Chinese marveling at the ancientness of the characters, so I translated it all into English for them.
You know what that proves? I suspect ~ but I don't know ~ but when you translate characters for Chinese using a book about Indian sign language that's gotta' mean something eh.
:’) Definitely.
Some years ago I went to the Epcot Center in Orlando. There was an exhibit on Pre-Columbian Mexico. There was one glazed drinking cup there that had figures on it that looked very Japanese to me. There is also the question of the Negro looking heads of the Olmec. I would not be surprised to find out that both Chinese and Japanese had some influence. I also would not be surprised about visits from the Mediterranean. One thousand BC the Myceneans (and possibly the Sea People) were using African mercenaries on their ships. It would not be too hard to imagine a ship or ships making it to the American’s, and the mercenaries taking over both the ships and the local settlements. That age was one of collosal figures and heads being produced in Egypt. That could explain the large Negro type heads.
