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
possibilities:

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
side.

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%).
