Why is there no looting in Japan?

This is from the Telegraph, but there are articles all over about the lack of looting in Japan. One should read the comments after this writeup to see how the tide is gradually turning in the UK and elsewhere.

And solidarity seems especially strong in Japan itself. Perhaps even more impressive than Japan’s technological power is its social strength, with supermarkets cutting prices and vending machine owners giving out free drinks as people work together to survive. Most noticeably of all, there has been no looting, and I’m not the only one curious about this.

And from Mail Online

Amid the chaos, foreign journalists have remarked on the polite demeanour, the lack of anger, the little if any looting or profiteering that seems to characterise disasters elsewhere.
