I snapped these pics in Tokyo's Narita airport in September. These hilarious illustrations were in a small travelers' health advisory office. There was a giant world map on the wall that was color coded for diseases like malaria (parts of Texas included) and dengue fever (Vietnam 100% included).
I don't read Japanese, but the main message I get from these posters is "Whoa! Scary stuff outside our island nation!" [Love that little red guy with the arrow and the expression on the victim's face.]
I read recently that a majority of young Japanese won't consider going outside the country because they consider it unsafe. Sounds kinda like a lot of Americans.
