I live here over 50 years but as far as I know, there are not too many Japanese that I know of. If you live in Orange park area, there are lots of military families do you may find some Japanese. I do know several Japanese ladies but they don’t have young children. I live in zip 32256 area ( south side ) and it is a very nice area and schools are good. South side is the safest area in town in my opinion. We have one Japanese owned small grocery store and several Chinese, Korean owned stores.
