Do you have an example? Your comment seems like an exaggeration, I have never seen any signs pointing to each other from every direction.

Also, I am curious of the justification. Why would anyone place signs that "... are incredibly confusing and often will all point to each other from every direction."

The problem I would typically have (not just in Shinjuku) was with directions that did not repeat/update as you continued on through junction points. It made navigation more stressful.
