There's Kikiwai -- an anime shop between Queen 
and Dundas on Spadina avenue. It's in the big 
blue shopping mall on the second floor -- look 
around for it since it's in a hidden corner. They 
don't have the best selection or price, but they 
do have cels. If you want a preview try 
www.kikiwai.com

As for Japanese markets -- I'm not too sure about 
them, but I believe there's a sweet shop on the 
second floor of that building which has a supply 
of Japanese drinks. 

I hope you enjoy your stay -- be prepared we're 
in the middle of a major heat wave.
