TOKYO (AFP) - A 5.9-magnitude earthquake hit Japan on Saturday (July 7) evening outside of Tokyo, swaying buildings in the capital, but no tsunami warning was issued.
The quake hit at 8.23pm local time (7.23pm Singapore), at a depth of 39km, off the east coast of Honshu, Japan, the US Geological Survey said.
Japan's meteorological agency said no tsunami warning was being issued.
There were no immediate reports of damage after the quake, a relatively rare strong tremor to hit the capital.
Residents in part of the Chiba region outside Tokyo reported strong tremors, with some saying the shaking had knocked objects from shelves, but there were no immediate injuries reported.
Public broadcaster NHK said no abnormalities had been detected at nuclear facilities in the region.
A spokesman for Narita airport outside the capital said the quake had forced a brief suspension of operations.
"We temporarily closed the runways but resumed operation after confirming there was no damage. The quake was fairly strong but there was no panic at the airport," he told AFP.
The quake comes several weeks after a deadly tremor rocked the Osaka region, killing five people and injuring over 350.
Japan sits on the Pacific "Ring of Fire" where many of the world's earthquakes and volcanic eruptions are recorded.
On March 11, 2011, a devastating 9.0-magnitude quake struck under the Pacific Ocean, and the resulting tsunami caused widespread damage and claimed thousands of lives.
It also sent three reactors into meltdown at the Fukushima nuclear plant, causing Japan's worst postwar disaster and the most serious nuclear accident since Chernobyl in 1986.
