When I was up in Tokyo for the JALTCALL 2007 conference in June, 2007, I had my trusty Panasonic Lumix DX-10 at my side. I thought I would take some shots of my travels around the city. I didn’t have much time for that because I was busy going to presentations, and when I wasn’t doing that, I was lugging my bag around (note to self: take the rolling bag next time).
I did manage to take a few shots. I mostly got shots of the Tokyo Metro System, but I did get one of the the JR system in Tokyo.
I grew up in Southern California, so I was new to subway trains in 1985 when I went to both Mexico City and Japan for the first time. If you’re a subway train veteran, thanks for reading this far. You’re free to go. 
Since I walk to work now, I still have to acclimate myself whenever I head into the big city (we do have a street car here in Kumamoto! 
)
Basically, you want to find your stop on the map above all the ticket machines, look at the price to get there, put your money in, and get your change and ticket.
Follow the crowds to the wicket, go through the section with a green arrow, and remember to take your ticket out as you walk through (you’ll need it again to get out of your station).
Look around and up, and find your train line. Make sure you check the direction and stay on that side (I still have a tendency to move to the side dodging people and forget which side to be on), so you don’t head off the other way or on another line. I almost got on another line on the way home the last day. Hey, it was Shinjuku station, and there are at least 20 tracks!
Head out of the train at your stop, and look for the signs that show you what is near each exit.
It is important to go out the right exit, or you could have a really long walk to get around to the other side of the station. As you leave the station, have your ticket ready. You need it to get back out; it will not come back to you when you exit.
If you get stuck, there are lots of maps in different scales to help you get your bearings.
You can also ask any of the workers on the platform or the windows. Remember, everyone wants to help you get where you want to go. Just smile, and say the name of where you want to go.
One huge difference I noticed this trip (it’s been at least four years since I spent any time in Tokyo) was the change in the signs on the trains. They are all electronic now, so the signs change as the trains move down the line, with the present and next stop in big ol’ letters. That made it harder for me to miss a stop.
Another tip is to not ride during peak times. This worked out for me every ride except Saturday night getting on the Yamanote loop line. I just kept walking until I saw a little space on one of the cars. I exhaled to get as small as I could, and I pushed my way on. Two more people got on after me, so maybe you get the idea of how crowded it can get. I understand some of the train lines use the conductors to push people on during the heaviest times of the day. Fun, fun, fun!
