I'm leaving to go to Tokyo right now. I take the overnight sleeper bus from Sendai, and it gets to Tokyo at 6am. Then, Stephanie's plane tentatively gets in around 3:30pm, if all goes well.
Of course, don't bother emailing me with the expectation that i'll read it before January 5th. It's possible but I can think of a million and one more exciting things to do in Tokyo and Kyoto. :)
