In respone to the comments to this post on Digg.com:
Repeat after me: There are no used panty vending machines in Japan. The third most common vending machines after soft drinks and smokes aren't the ones for porn. We don't have supermarkets staffed by robots. You don't see "many many bars and other services that have big signs saying 'NO FOREIGNERS'." Are the Japanese "beta testers for future technology"? I don't think so. At least not the ones in my neighborhood.
