A powerful 6.2 magnitude earthquake has struck off the coast of Japan near Fukushima.

Details of the extent of the damage have not yet emerged regarding the quake which hit 281km South East of Kamaishi.

The depth of the earthquake, which struck at 2.37am local time, was measured at 10km.

A similar earthquake back in 2011 killed 15,894 people and injured 10 more when a tsunami, landslides and fires broke out as a result.

But experts are predicting today's quake should pass by without causing any harm.

In June, five workers at a nuclear research facility in east Japan were exposed to radioactive material on Tuesday after a bag that contained it burst, the plant's state-run operator said.

Japan's nuclear industry has been in tatters in the wake of the Fukushima disaster in 2011, with parts of the public deeply skeptical about the safety of atomic energy.

Japan shut down all of its atomic reactors after a powerful earthquake in March 2011 spawned a huge tsunami that led to meltdowns at the Fukushima nuclear plant.

It became the world's worst nuclear accident since Chernobyl in 1986.

Since then, just a handful of reactors have come back online due to public opposition and as legal cases work their way through the courts.

However, Prime Minister Shinzo Abe has aggressively promoted nuclear energy, calling it essential to powering the world's third-largest economy.

Much of the public remains wary of nuclear power after the disaster at Fukushima spewed radiation over a large area and forced tens of thousands to leave their homes, with some unlikely to ever return.
