I've just updated the Tokyo Yarn Store List (click to download the excel file). This list was originally started by Tricoquelicot for the Tokyo SNB yahoo group and then I just added some commentary and other details to make the list more complete. The only real change to the updated list is that the Rowan store in Ebisu moved and I also added opening hours and regular closing dates for stores where possible. If you have any other stores that should be added to the list let me know.
While updating the list and searching store websites I found some pretty cute free patterns for some slippers and hats on the Puppy website. The first slipper pattern seems very similar to the very popular pocketbook slipper pattern.
I'm not so sure about the hat pattern though - seems a little too tea cozy-ish like for me.
