The past two months have been uncomfortable for Japan, and for the country's foreign residents. Non-Japanese (NJ) have been bashed in the media, unreservedly and undeservedly, as deserters in the face of disaster.
Consider the birth of the epithet "fly-jin." A corruption of the racist word gaijin for foreigners, it appeared in English-language media as a label for NJ who apparently flew the coop in Japan's time of need. The Japanese media soon developed its own variants (e.g., Nihon o saru gaikokujin), and suddenly it was open season for denigrating NJ.
For example, the Wall Street Journal (March 23) announced in English and Japanese articles an apparent "fly-jin exodus," portraying NJ as fleeing, then sheepishly crawling back to their Japanese workplaces to face hazing. Tokyo Sports Shimbun (April 14) ran the headline "Tokyo Disneyland's biggest reason for closing: repatriating NJ dancers" (oddly, Disneyland reopened days later).
