We also rode a lot of trains. I really want an awesome train system in America. (Of course, geography makes it easier to do it here and harder to do it there. But still!) I'm impressed at how clean the stations are and how smooth the ride is. I guess when everybody uses transit, there's some incentive to keep it kinda nice...
The best part of seeing the big Gigantor statue is that we stopped in the subway station on the waya back to ask an attendant if he knew where Robb might buy one of the posters they had, he just said "um, here" and pulled one off the wall for him!
We had breakfast at Mister Donut, because Greg developed a hankering. I had a chocolate-dipped green tea donut that was really, really yummy. I think in large part because it was not overly sweet.
I've been watching the architecture a lot from the trains, and it took me a while to figure out what makes the urban landscape look distinctly Japanese. Because most of the individual buildings would not look out of place in the U.S. (other than a tendency to have stairs on the outside, and to make them into design elements instead of just fire escapes). Eventually I realized that it's very simple: the buildings are all close, there's a lot of them, and nothing is only a single floor.
