Yep: in Tokyo, the stations and the system are complex because of the sheer size of it. Hundreds of stations, so many exits at many of the stations, multiple different companies running the various lines, etc. However, the operation is simple: everything works like clockwork, except when there's a "human incident" (someone jumping in front of a train), which thankfully is fairly rare but does happen unfortunately. Except for exceptional circumstances like that, you can count on things working reliably all the time: trains coming exactly when they're supposed to, on the track you expect, not skipping your station, etc. These days, it's really easy with Google Maps. Just tell it where you want to go and follow the directions. It tells you the station entrance, which platform to stand on, which car to ride in, when the train is coming, if there's a delay, and which exit to use.
