Really? Do you know how badly the Japanese treat women? And there are terrible human rights issues there. When prisoners are executed, they're given virtually no notice and so have no opportunity to fight it. Whereas some states in the US have the death penalty, prisoners spend years on Death Row fighting it. They have rights. If your holiday choice is dictated by a country's politics, swapping the US for Japan is a weird choice. And NY state doesn't even have the death penalty.
Your DD is going to read about Japan and feel even worse about going there than the US! (Because she'll presumably read up on it, having a strong social conscience that led her to reject NY.)
