Why aren't Japanese looting?

Over at ROK Drop, GI Korea poses the above question (also asked at CNN and elsewhere), with some concluding that "Japanese are far more developed humans than Koreans will ever be" (it's a K-blog comments section, so what would you expect?).

I've been discussing this very thing with "M" and some other people from Japan or who have lived in Japan, and these are the conclusions we came up with:

1. Thanks to the graying of Japan, the number of elderly and older people in the affected area is proportionately much higher than in other areas around the world that have been affected by earthquakes and/or major tsunamis.
2. Just about everything worth looting has been destroyed in the affected area.
3. Too much shock to loot.
4. Strict adherence to a family registry has engrained in people the idea that their bad acts, if found out by the authorities, could adversely affect their family members, which seriously lowers the propensity to commit such bad acts long before opportunity arises.
5. None of the big league sports teams in the Sendai area just won a national championship.

Back at ROK Drop, the discussion diverged into how South Koreans would handle such a disaster. I believe that what would happen is that there would be little or no looting, but there would be a lot of pushing and shoving at some (not all) of the areas offering assistance, as well as a lot of yelling at aid officials.

Back to Japan, some are offering other answers, and I myself would like to submit that the no-looting condition of Japan is not only a goal for other places, but is also an achieved state in many cases. There was little or no looting after 9/11, nor after the major quakes that struck California in 1989 or 1994 (I think).

Honestly, if I lived in this neighborhood and I thought all this merchandise was going to end up being worthless thanks to the flooding, I'd be tempted to loot, too.
