If you do an image search for, say, "world atlas," you'll see all the maps have cut the Pacific in half, so the West Pacific is at the right edge and the East Pacific is at the left edge of the map.

Now, if you search for, say, "세계전도", then you'll see that most maps have cut the Atlantic in half, because otherwise kids (for whom those atlases are intended) would see their own hometown shoved all the way to the end of the map.
