Bon Jovi has released two dates for Japan, just before the Australasian leg:
November 30, 2010 - Tokyo, Japan - Tokyo Dome
December 1, 2010 - Tokyo, Japan - Tokyo Dome
Wouldn't surprise me to see more shows added though.
As a side note, I've been trying to work out the band's flight plans... for example, they're going to be in Japan, then fly eastward to New Zealand, then to Western Australia (which, if my mediocre geography skills haven't failed me, is closer to Japan than it is to NZ), then back to the eastern states of Australia?
