Ugliness is subjective. Tokyo is varied but to me that's generally nicer and more interesting than uniformity. I don't think there's any part of Tokyo that looks as bad as the Barbican or the Brunswick, and to me the endless rows of identical beach-hut-style houses in San Francisco were far grimmer than Tokyo. YMMV I guess.

I'm not a huge fan of the look of the gravel parks, but every kid having a nearby park that they actually use beats a handful of parks that look nice, IMO. And it's not like Tokyo doesn't have big beautiful parks as well.
