Help me to assemble a comprehensive Japanese grocery store and bento source list!

In case you read Just Bento but not Just Hungry - I'm finally embarking on a project I've always intended to tackle, but never got around to: putting together a good listing of Japanese grocery stores around the world. I'll include bento supplies too, since many people who are interested in bento making are also interested in Japanese cooking, and vice versa.

If you have any stores, mailorder sources, and so on to recommend, please head on over here. With your help I'm hoping to assemble a really useful list!
