Japan has much tighter controls on their media. Culturally the entire country will be concerned about saving face. They will not air their dirty laundry.
That sounds more like China.
There will be no way to avoid any "dirty laundry" escaping the scene considering the survivors & global news media having access to the area and unrestricted access to the net. You're aware that there is video of their nuclear reactors exploding, right? Doesn't get much dirtier than that, and the vid is out there whether the gov. wants to restrict it or not.
Plus, disaster & suffering sells. People can't get enough.. that's the very reason photographers will stand by and take pics while dead babies are being tossed through the air. Supply & demand.
Are some people there looting? Undoubtedly.. but I don't think it'll be anything on the same scale as New Orleans after Katrina or the (ongoing) mess that is Haiti.
It's the Japanese culture. Stand by and watch how they handle the disaster and compare it to how past events were handled by lesser cultures.
