salt affects certain portions of the population really badly
but it also is basically a non-issue for others
if you have a high salt diet, consult with your physician about your blood pressure instead of guessing if you're one or the other

It's not so much that high sodium is bad for cardiovascular health, it's an imbalance of sodium and potassium which causes the problems.
Although japanese (and korean) diet are high in sodium, they also regularly eat a lot of soy beans, which have the highest potassium by weight of any bean. Also other high potassium foods like certain kinds of fish. That being said, high sodium diets also increase your risk of developing colon cancer, and we can see that japan and korea have a higher than average rate of colon cancer, likely in part due to their high sodium diets.
