While it doesn't detract from the article's main point, that Japanese prison conditions are poor, but arson, murder, and jaywalking much? Overstaying your visa is a lot more egregious than the other infractions.

I know this is sarcasm, but going to Japan as a tourist and _living_ in Japan as a resident -- or the same of any country, for that matter -- are very different experiences. Some, but surprisingly little, of your experience from the former carries over to the latter.
