As the thread title suggests, I'm going to Tokyo from France for a week-long conference in the first week of September. I'll have a couple of evenings free, as well as an extra day after my conference is over. I thought I'd poll the MR crew to see what's not to be missed while I'm there, although I realize that my time is too limited to really see much. The conference is being held at Waseda University, and I'll be staying at a hotel about 5 minutes away by metro. Thanks in advance for the help.
