"Around a dozen Japanese tourists a year need psychological treatment after visiting Paris as the reality of unfriendly locals and scruffy streets clashes with their expectations, a newspaper reported Sunday."

"Previous cases include a man convinced he was the French "Sun King," Louis XIV, and a woman who believed she was being attacked with microwaves, the paper cited Japanese embassy official Yoshikatsu Aoyagi as saying."
It seems like those French have done it again.
