Large areas of Japan's northern Pacific coast have been swamped by a devastating tsunami, engulfing entire towns following a major 8.9 offshore quake.
The massive wave of water, as high as 10 metres in some parts, reached more than five kilometres inland.
The death toll has already reached 23 and officials say an unknown number of people are missing.
Seismologists say the quake was 160 times more powerful than the one that devastated Christchurch last month. It is understood to be the seventh largest earthquake in recorded history.
