Clearing the rubble, one year on from Japan's tsunami
Issued on: Modified:
On March 11th, Japan will commemorate the devastating tsunami that ravaged the Tohoku region one year ago. This report highlights the daunting task of managing the mountains of rubble left over from the post-tsunami clean-up operations - some 23 million tons. The task is further complicated by fears of radioactive waste around Fukushima, posing risks to those involved in the mammoth operation. Our correspondents Marie Linton and Guillaume Bression were there.
