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.
