I'm still not convinced (call me skeptical) that many of the "ethnicity"
tests can accurately tell the difference between Native American and East
Asian. Some of them even state "Native American OR East Asian" ethnicity (the
probably ASSume you know which is which). If you take the percentage they
claim is NA and add it to the East Asian it would probably be more accurate
in identifying the Japanese ancestry percentage.
Of course, it couldn't be ruled out that there would be the possibility of
Indian (Native American) blood in the Mexican ancestry as well. On that
Faces of America TV show didn't Eva Longoria's DNA test show some Native
American ancestry in addition to her Hispanic/European heritage?
I also know 23andme states in their Native American Finder that any NA
ancestry further back than 3rd great-grandparents is probably "lost" and won't
show in your results.

Linda, if you did the swab yourself (and it was a few years ago), we
know that it wasn't a Y-chromosome test. That leaves us with two
1. A mitochondrial DNA test. This would represent only your distant
ancestor on your mother's mother's mother's (etc.) line. This would
explain why there would be no information at all about your father's
line (including the fact that his father was 100% Japanese), since the
DNA that was tested would have come to you strictly from your mother's
2. An autosomal DNA test. This represents a combination of DNA from
both of your parents. While you would normally get 25% of your
autosomal DNA from each of your 4 grandparents, in reality the numbers
could vary a lot, which again would explain why you would see only 6%
East Asian (instead of 25%).
