This is Tokyo station. Actually, this is a highly simplified view of part of it.

We'll also go through it a time or two. Obviously, you DO NOT want to take a wrong turn.

There are signs everywhere, but we can't read most of them.
There are streams of people. No, RIVERS. TORRENTS. FLOODS of people hurrying every which way.

We'd hate to lose you or see you carried off in the current never to be seen again.
So we've developed a few strategies for navigating crowded stations/streets.
So far, we haven't lost anyone.
