Anyone who thinks that Japan, as co-host with South Korea of the World Cup finals due to kick off on 31 May, is taking the threat lightly hasn't watched Japanese TV lately. Night after night viewers have seen exciting sequences of the Japan riot police taking on other policemen pretending to be football hooligans who, for extra realism, wear white shirts with three red lions, wave Union Jacks and shout things like "WE VELLY TOUGH CHAPS" (after a gentlemanly protest by the British Embassy, the pretend hooligans now wear more varied outfits). The police, who script these shows, always win, of course.
