The tremor, which hit just before midnight, hit at a
depth of around 22 kilometres (14 miles), around 34 kilometres
south of Shizuoka and 162 kilometres south of Tokyo, the US
Geological Survey said.
The epicentre of the quake was a considerable distance
from the 9.0 magnitude earthquake that rocked Japan on March
11, generating a massive tsunami that wiped out whole
stretches of the country's northeast coast, leaving more than
20,000 people dead or missing.
Thousands more were made homeless when a nuclear
reactor began melting down after its cooling systems were
swamped by the waves in the worst atomic disaster the world
has seen for a quarter of a century.
Japan, located at the junction of four tectonic
plates, experiences 20 per cent of the strongest quakes
recorded on Earth each year.
