Heh, we have a running gag here that whenever we hear of a murder or kidnapping or something on TV news, we guess "it happened in Kansai", and unfortunately I'd say 4 out of 5 times we're right.

Interestingly enough, I brought your list up to my wife who said "I find it hard to believe that Osaka is the worst. I bet Wakayama-ken's statistics are worse than Osaka." I think her opinion belies that Japanese tendency to consider urban areas as more regulated and safe and rural areas as wild and depressed.
