If you have to spend a minute or more to read something which might or might not be useful, that's an annoyance, I would even say disturbance. Takes precious time to find the right information in a place where minutes or even seconds matter. If you never lived in Tokyo then you have no clue what I am talking about. If you did, you would exactly know what I am talking about.
Many thousands of people living in Tokyo right now disagree with your middlebrow Internet contrarianism.
This isn't an art protect, it's an actual part of the subway system that has been in place for a long time, providing ad hoc guidance in the face of sudden alterations due to construction in progress. Have their been complaints about how it has harmed anyone's ability to navigate?
I've lived in Tokyo for many years and have no idea what you're talking about. The characters are very peculiar but completely legible at a glance, and the maps are incredibly informative.
So there is a illegible distorted text which seeks attention to occupy your view and you don't know what I am talking about? Have you heard of navigation?
Also the definition of distorted: "giving a misleading or false account or impression; misrepresented."
