Also thinking of maps and Japan: where I am from (Germany) public overview maps of parks or street maps usually have north as up. In Japan however it is very common for those maps to have up as the cardinal direction you are looking at the map at. So if you are looking at the map in a western direction, the map will have west up. So for walking the map is straight up, backwards down, left left and right right.
Like that it is very easy to know which way to go. Want to go to some place that is on the left on the map? Turn left!
