One, I don't necessarily have any reason to be impressed with the areas you reference, particularly the south eastern USA. It's debatable to what extant they can make the claims you've claimed for them. I do notice that both the south USA and Japan have a massive xenophobic streak, I'd suggest that has more to do with cultural cohesion (whether or not cultural cohesion is even a good thing).
Secondly, nothing you say shows us that these societies are succeeding (if they are) because of honor culture, and not in spite of it. Japan does have one, but it's frankly been really watered down from what it used to be. As it stands, the significance of an honor culture in a society does seem to inversely correlate with its development. Third world countries and so-called failed states or zones of chaos show us the strongest honor cultures, while the advanced first world democracies tend to show us the weakest honor cultures. Japan might be the biggest exception there, but then modern Japan's honor culture has no comparison to Afghanistan's. This trend continues within countries. The south east may have the strongest honor culture, but it is frankly also the least advanced region of the USA. It has the worst education, the worst health, and the most poverty, last I checked. Problem pockets exist in the rest of the USA, of course, but generally the south east is the worst off.
In short, honor culture does not make a good name for itself.
