It's unlikely Ayumi would've donated anonymously knowing that Avex wants to make big bucks out of her, they would've insisted on making a donation on her behalf. She did donate for the anti-drug thing in Thailand, but it turned out to be a smaller sum than I thought when you convert it from the Thai money (Rubles?). I dunno, Ayumi makes a lot of money but most of it goes to her handlers (of which there are many). Still, I hope that she donates something in the future (or has in the past) because the tsunami relief will last years.
