Do you know if she came late to Japanese, like Selena with Spanish and Drunken Tiger with Korean, or if Japanese was spoken at home, hence fundamentally native to her?

(My friend Luc Sante, who moved to New Jersey from southeast Belgium when he was ten, wrote a book I like a lot called Factory Of Facts, fundamentally about having English layered on top of his original French, though the situation - and the book - are a lot more complicated than that, given that his part of Belgium had two different, though related, languages (French and Walloon) and Belgium itself is divided by language between Flemish and French and is apparently getting more so. In any event, for a while Luc found himself thinking in English and feeling in French, to put it too simplistically. I think you'd have a lot to say on such subjects. Also, are you familiar with Alex Ostroff, who posts on the Jukebox and on ilX (also has a livejournal that he doesn't use much)? He lives in your city; and among other languages he knows Spanish, and he's been telling us what is going on in "Loba" that's not going on in "She Wolf."
