tbh I believe she truly wanted to move to USA. I don't think it could harm her career or so
she always was that type of a Japanese girl who wanted to look Western, think and act Western, she said she loved the feeling of freedom which USA gave her. and I'm sure she's been studying English since 1997 when she first stepped NY. tbh I believed her when she said she couldn't be separated with Japan after disaster. I think it's also crushed her wishful thinking about USA, how it'd different there. when disaster happened, she understood that she's Japanese after all, that she's a famous person and she CAN help and courage her nation. life's changed after disaster
