On pristine pitches in northeastern Japan, the Argentine men¡¯s rugby team practiced their scrums, line-outs and set plays in the sunshine in preparation for their opening game against France this week in the Rugby World Cup.

About a year ago, the ground beneath their feet was covered with parking lots for the hundreds of workers who had to contain and then clean up the world¡¯s worst nuclear disaster.

But residents and businesses in the region are still struggling to persuade the world that their towns and produce are safe.
