Japan prepares for an earthquake

Last updated at 05:12

A massive rehearsal has taken place in Japan to prepare people for what to do when an earthquake hits.

It's the country's first national earthquake drill since the huge quake and tsunami in March which left 20,000 people dead.

Tremors are common in that part of the world so officials want to make sure that if disaster strikes again, everyone is ready.
