It struck about 250 miles (400km) from the capital at a depth of 20 miles. There have been powerful aftershocks.

The tremor hit at 1446 local time (0546 GMT). Seismologists say it is one of the largest earthquakes to hit Japan for many years.

The Pacific Tsunami Warning Center said the wave could extend as far as Chile.

Farmland around the coastal city of Sendai was submerged and the waves pushed cars across the runway of the city's airport.
