When Japanese is written horizontally, it can be read either left->right or right->left. (occasionally, quite bewildering)
I have only seen right->left on signs; I have never seen it in books or magazines.

In signage you can have one character per column (kind of like one word per row on some English signs), making it look like right-to-left text.
