Tokyo's trains have some of the best signage in the world. Nearly all the ones in Tokyo and other major cities have English directions. All the stations have color coded numbers like G12 or N13 if Japanese names are hard for you.
Signs on the tracks tell you what station you're at, what the previous station was and what the next station will be.
Every exit has a number and signs on the walls and ceilings tell you which way you need to walk to get to your destination or transfer.
At the gates there are always maps of the area on the walls to lookup where to go if you don't have a smartphone.
I've been all over the world and I can't think of another transit system that has all of those features. Others are always missing one or more.
As for the person below that mentioned they got help in Ikebukuro station, it's great they got help, but I suspect in their panic they didn't notice all the signs. There is no exit from the JR lines that does not have clear signage to every other line (tobu, seibu Ikebukuro, fukutoshinsen, Marunouchi, Yurakucho, ...)
>There is no exit from the JR lines that does not have clear signage to every other line
Several times I have come across a station (like Shinjuku) where I can see the same sign for the same train line placed in 4 or 5 different areas (all visible at once) all pointing in different directions.
that's because both directions will get you to the train you're trying to get to. Example: From JR either west exit (then turn right) or the east exit (then turn left) will lead to the Marunouchi line. Pick one and follow the signs. That's no different than a subway with multiple exits on to the same street at both ends of the station
Similarly there's at least 3 perpendicular corridors connecting the JR tracks themselves so the exit to each corridor (of which there are 2 each so 6 exits) will all be labeled as leading to the other tracks because all of them actually do lead to the other tracks.
