Lost in Orientation: Subway in Tokyo
Tokyo has 13 subway lines and 168 subway stations. The lines spread like a web in the ground.
Strangers at Tokyo will be a little hard to change trains. Going down to the underground, they will soon lose a sense of orientation and get lose, especially at a line-crossing station. Without any guide board, they are very hard to go to the platform they want.
By the way, Roppongi, famous for the entertainment spot for foreigners, Station of Oedo line is quite deep, and astonishingly at a depth of 42 meters. To go the station, people need to use escalators, or stairs for dieter. The station may be better for dieter!
