Here in the U.S.A., I get my film from The Frugal Photographer http://www.frugalphotographer.com/ or Blue Moon http://bluemooncamera.com/index.php

My favorite lab is Bison Photo http://www.bisonphoto.com/Home_Page.html They will also provide your photos scanned on CD. There are other labs that do 110, but don't do the CD

I know that's a long way from Toyko, but maybe it will help.
