One of the big construction trends in Tokyo has been putting train lines underground. Given the space crunch here, I can see how it makes sense. I think most of the land will be given over to construction and not green space. While I can understand the economic impetus, I really think it heightens a feeling of detachment from one's community and decreases the aesthetic value of a place. Granted, the trains can be crowded, uncomfortable and sometimes smelly. But some of the best lighting...

I'm doing a walking trip in Japan. I started at Nihonbashi in Tokyo and hope to end up in Odawara by Friday. Please check out my blog: http://traveltokaido.blogspot.com/ Thanks!
