The phenomenon, which the newspaper dubbed "Paris Syndrome", was first detailed in the psychiatric journal Nervure in 2004.
Bernard Delage of Jeunes Japon, an association that helps Japanese families settle in France, said:
"In Japanese shops, the customer is king, whereas here assistants hardly look at them ... People using public transport all look stern, and handbag snatchers increase the ill feeling."
A Japanese woman, Aimi, told the paper:
"For us, Paris is a dream city. All the French are beautiful and elegant ... And then, when they arrive, the Japanese find the French character is the complete opposite of their own."
