There's that movie where Tom Hanks has to live in an airport for awhile. In Tokyo Station I sometimes feel I'll get hopelessly lost in there and will have to live in there for awhile. For a station used by so many people, from so many countries, you'd think they'd have plenty of signs. You'd be wrong! Then there are the posted station maps. They don't include the JR Green car reservation offices. They were on the online maps I looked at, but not official maps posted in the station.
Then the tracks. . .a woeful lack of information. I was looking for Track 21 but saw signs only for Tracks 1 - 9. I kept walking. . .and walking. . .and finally saw signs for tracks 10 - 19. I hoped there were more gates. There were, but I had to go through yet another gate. By the time I found the elevator and got upstairs, my train was just pulling away.
The station is accessible. . .sort of. It is if you know which way to go. For example, trying to get to Track 21. If you came the way I did initially, you must take a few steps at one point. But if you come at it from the other side, it's smooth sailing. You might not know that, though. If there are stairs, every track must have an elevator, too. If you find the track, it's usually not too difficult to find the elevator.
Anyone can get into parts of the station. To get to the tracks, though, you must have some kind of pass or ticket to get you through one of the gates (see the next paragraph). Now if you are on the Shinkansen or an express train, you will need to pass through an additional set of gates using your pass or ticket.
There are electronic display boards overhead that show the departure time, train, number, and track. If you don't see your train, either you're in the wrong place, or you're in the right place but there too early for your train to show up. The display cycles between Japanese and English.
The JR Pass just changed; you no longer show it to a staff person to get in and out. You now feed your pass (which looks like a JR train ticket) into a yellow slot in a pass gate. The gate will open and your ticket will pop out farther down on the gate. Just make sure to grab it and safely tuck it away. You'll need it again when you exit any station. Note that not all pass gates accept JR passes. Look for the one or ones with that yellow slot on the right. You can't go in or out of the ones where a card has to be tapped.
The Yaesu Gates are on the newer side of the building, so it's a bit more accessible. The Marunoichi Gates are on the historic side of the building, so there are more steps.
Restaurants are scattered about, but most are downstairs in an area known as Gransta. There are underground entrances and exits (gates) on this level. There are also convenience stores, sweets places, and more shops on all levels. Tracks have drink vending machines and stands selling ekiben or other food.
Once at the proper track, check your ticket for your car number and find on the ground where that car will stop. It can get a little confusing because different types of trains of different lengths use the same track. So car 10 for one train might be car 9 for another. But all cars are connected so if you're cutting it close, just go in the nearest open car door. You can then work your way to your car and your seat inside the train. Better that than missing your train. Trains in Japan run to the second so they will not wait for you.
