I studied abroad in the Fall of 2009 at Waseda. It's a great University in a great location (I particularly loved Nishi Waseda and Takadanobaba) so enjoy it!
I actually don't know where I'll be yet. Since my project is a political science field research one and not in a lab, the Japanese Fulbright commission will place me at a University. So I have no idea when I'll know my location.
Good luck with yours!!!
