It’s 10 years since Japan was hit by a large 9.0-magnitude earthquake, triggering a large tsunami. Alongside the north-east coast dozens of cities and villages have been engulfed by the wave. The catastrophe triggered a meltdown on the Fukushima Daichi nuclear plant 250km north of Tokyo.
The BBC spoke to Kiyokazu Sasaki who misplaced his complete household when the tsunami hit his city.
