Anchan will do a Special live at the Flea Market for Tohoku (same day as the MTV VMAJ) and there you have an USTREAM link. The USTREAM starts at 9pm (Japan time)
As I said before, Anna will attend the MTV VMAJ as a presenter and maybe she'll perform Wonder Woman with Namie Amuro! But Anna is only confirmed as a presenter.
I don't know how the hell will she do to be in two places at the same time xDDD I think the Flea Market and the MTV VMAJ are in the same place right? Because the Awards and the Market are at the same hour xD
