Mourning the loss of almost 20,000 people gripped Japan yesterday on the anniversary of the March 11, 2011 earthquake, tsunami and nuclear disaster. While the nation has made enormous strides recovering from the triple disaster, yesterday was was a time for remembrance. But the country is rebuilding even as it still suffers the loss of lives and the economic effects of an estimated $210 billion price tag - the costliest natural disaster in human history. Gathered here are images from memorial services, the rebuilding efforts, and of people forging ahead with altered lives a year on from the catastrophe. -- Lane Turner ( 40 photos total
