As I mentioned in the previous post, kids in Japan can run around by themselves and there are few cases in which it ends in tragedy. At this point in time, there just isn't much risk that kids will be abducted (fortunately). However, it is very common for parents to take their children's safety for granted, particularly when they are with them. I've seen uncountable numbers of parents with children who are just past toddling age who allow their kids to run far out ahead of them, including approaching streets through which cars are passing. It's also not uncommon for parents to allow their kids to clumsily run around on train platforms as they chat or play around with their cell phones.
Perhaps I'm just paranoid as a non-parent, but it seems that Japanese parents worry little about where their kids run around in public and I won't miss thinking that they take their safety for granted or rely on strangers to keep an eye on their kids.
