Japan's Prime Minister Naoto Kan arrives at the evacuees shelter during his brief visit to Rikuzentakata, after the area was devastated by a magnitude 9.0 earthquake and tsunami April 2, 2011. Kan was also headed on Saturday to the disaster zone where workers are braving radiation from a crippled nuclear plant to battle the world's worst atomic crisis since Chernobyl. Kan was due to visit a sports camp turned into a base for military, firefighters and engineers working inside an evacuation zone to cool the six-reactor Fukushima Daiichi complex and contain contamination before Japan seeks a permanent solution.
