I commute to work by train for more than 7-years from Yokohama to Tokyo.
I see the cities view transition . It is very exciting to me.
Tokyo & Yokahama is now under wide-scale redevelopment.

See the following sites if you interested in landscape of Tokyo.

writen in Japanese only. Click & see.

There is the System of Anti-Google.

To say reluctantly, the Site is writen in Japanese only so that
it is hard to understand how to use.
But it is very useful I think.

This site is the search system which targets sites of geting out of
Google search target.
To be opposed to Google's huge System, ∞Eyes Project was formed.

I live in yokohama.
On every weekdays I go to office of my workplace in Tokyo.
About 1-hour I spend in the train to my office and about 1-hour I spend in the train to my house.
Ordinary people living in Yokohama maybe takes the same time in the train as me.
In-train hours many people are playing the game Wii , playstaion-portable(PSP) and listning to music with iPod.
I sometimes encounter the person who suddenly laugh listning to the fun story by iPod.

Some peple read blogs connecting the net with the cell-phone.
A few people is watching TV with the expencive cell-phone.

Everyone is lisning thorugh headset and nobody talks , so it seems very starange for foreigner I think.
