Japan has marked the third anniversary of the devastating earthquake and tsunami that killed 15,884 people and left 2,636 unaccounted for.

During a ceremony in Tokyo, officials and representatives of the survivors offered a minute of silence to mark the moment when the magnitude 9.0 earthquake struck off the Tohoku coast. It was the strongest quake recorded in Japan's history and the fifth strongest ever recorded anywhere in the world.

Three years later, nearly 270,000 people remain displaced from their homes, including many from Fukushima prefecture who may never be able to return home due to radioactive contamination.
