A decade has passed since that fateful day in March 2011. People say they remember where they were when they saw the live footage of the tsunami crossing the coastline north-east of Tokyo, in an area called Tohoku.

Nearly 20,000 people perished. For a while, the world watched in horror at the scenes of devastation, worried about the fallout from Fukushima, and marvelled at the stoicism and strength of the people of Tohoku.
