The vernacular media frequently goes tsk-tsk over crimes by juveniles. These days, people's concerns tend to be reflected through two terms: "kyoaku-ka" and "teinenrei-ka," which refer, respectively, to more violent crimes by increasingly younger perpetrators
Unfortunately, the media and the public tend to dwell a bit too much on the bad kids and not enough on finding more ways to insulate kids from the bad adults who prey on kids at every turn.
Japan may fancy itself as a society where young people are nurtured with care, but when they are hoodwinked and exploited so openly, and on such a vast scale, it makes me wonder what's going on in the nation's homes, schools and regulatory agencies.
