A couple pay respects at a shrine set up at the destroyed disaster prevention center building at Minamisanriku in northeast Japan Sunday, Sept. 4, 2011. Dozens of people took shelter on the roof of the three-story building during the March 11 tsunami, but about 10 survived after the rising waters swept the others off the roof. Japan marks six months since the disaster on Sept. 11. &#40;AP Photo&#47;Greg Baker&#41; <span class=meta>(AP Photo&#47; Greg Baker)</span>
