Having spent a fair amount of time there, I can say that Japan is one of the most honest countries on earth. As another poster upthread stated, if there is any looting going on it Japan, it is not being done by the Japanese, that's for sure!
3 years ago while on business in Tokyo (I used to work about 5-6 weeks a year there), I took a long weekend trip to Kyoto by train. Whenever I get off a train in Japan, I always look at my watch, because I am continuously amazed at the fact that trains are ALWAYS on time there - to the minute. So I know that I looked at my watch right before I got off the train in the very large Kyoto train station.
By the time I got to the taxi, my watch was gone - nowhere to be found. So I knew that I'd lost the watch in the train station. Of course, being an American, I immediately despaired of ever seeing that watch again - I didn't even bother reporting it, since here, it's pretty much 'finders keepers' - especially with nice jewelry (and this was a nice watch).
5 days later, back at work in Tokyo, my Japanese co-worker noticed me looking at his computer screen for the time, and commented about my missing watch. I told Goto-san what had happened, and he told me he was certain I would be able to get my watch back. Right then and there, he called the Kyoto train station...and 3-4 min later was told that not only did they have my watch, but they would be happy to Fedex it to me free of charge.
THAT is the kind of culture you are dealing with there, folks. And there was never a single doubt in Goto-san's mind that we would easily find my watch, either. I don't think it ever occurred to him that we wouldn't, because when I told him that in the US, the watch would almost certainly be gone forever, he was really surprised.
What a country!
