Such was the force of the quake, Japan moved 12 feet closer to the USA, the Earth was knocked off its axis and the rate of the planet's rotation was changed. This was one of the biggest earthquakes ever measured; the ground along the east side of Japan dropped by almost 10 feet, making the tsunami catastrophic.
The documentary also follows renowned journalist Callum Macrae as he travels to the north, where the towns of Sendai and Ofunato used to be bustling fishing villages. Here he views the destruction first hand and meets the locals struggling to cope in the aftermath.
As Japan lives with the consequences of this terrible catastrophe, the film reveals how it has changed the country forever.
