This makes it hard to get directions if you want to drive anywhere.
Most Japanese people know how to get somewhere, but they couldn't tell you how (even if they are capable of explaining it in English). Usually you will either get "It's near 7-11" or a hand drawn map that looks like this:
My boss drew this for me so I could get to a teaching job that was an hour away. Mister Donut is at the top left.
They are pretty good with landmarks, however. For example:
They do name their intersections. But nobody remembers them. And don't bother consulting a map, because they're all written in Kanji (the most complicated of the three Japanese alphabets). So my advice is to either stay where you are or memorize where all the 7-11s in Japan are.
