McDonald's in TokyoThe image of Japan as being inhospitable to imports is old, enduring, and not entirely unjustified. The government is offering immigrants from South America—many themselves descendants of Japanese emigrants—$3,000 to return home (the better to free up jobs for native-born Japanese). The vista that meets visitors at Narita Airport is hardly more welcoming: masked staffers, health disclosure forms, and a sign warning that people who are coming in from countries such as Bolivia and Brazil must go in a special line. (They're looking for either soccer players or swine flu.) On the 80-minute ride from Narita Airport to Tokyo, I tried in vain to spot an imported car on the road.
