We are here and our days have been packed. Most free time has been spent desperately trying to find accommodation for the weekend (we just succeeded this morning). I could live in Tokyo in a heartbeat... but there aren't enough drinking bars. You always have to eat when you drink. But even old businessmen (especially old businessmen) can be found drunk as college freshmen any day of the week. Talk to one of them and hilarity ensues.
The train system is a breeze. New York two weeks ago (I was in New York two weeks ago?!) was the perfect primer for Japan. We are pros.
