A big part of Japanese TV entertainment involves stereotypes. Many times when they are on location at another country they would use stereotypes to describe local population, such is they assume all British don't rinse off soap when washing dishes, or all Italians throw garbage from balconies, and so on. Apparently this kind of stuff increases rating on their TV programs, so I guess ANA went with same model, completely forgetting that they may have to fly some foreigners around.
Bad move, even though some Japanese think that us, foreigners are paranoid.
