Somehow that text made sense... The only word I paused for a second at was pweor. It might also help that I've seen this kind of text before.
As for the Japanese version of this, I have no idea.

I would go so far as to say that every literate native could read that - some may take a bit longer, but...

Half the people on the internet write like that. Of course they can read it.
