Joe, always the first to point out when I'm wasting my time, noted that this time would probably be better spent packing. I don't leave for another 36 hours--what's he talking about? At least my laundry is done.
Stuff to buy before I leave:
Underwear (you can never have too much)
Socks
Deodorant
Toothpaste
Film. Lots and lots of film. (p.s.-if anyone wants to donate a digital camera, you'll get a special shout out.)
Fleece Jacket. It's a little chilly in Tokyo.
