An earthquake measuring 5.6 on the Richter scale has struck off the eastern Japanese coast, just north of Tokyo, the national NHK broadcaster is reporting.
Local news outlets say the quake was felt in the Saitama and Tokyo areas, with buildings swaying.
Metro operations were briefly suspended on all routes in Tokyo, but services restarted four minutes later.
An elevator maintenance firm in Tokyo said several elevators stopped in the metropolitan area due to the quake with commuters asked to “use emergency buttons,” according to NHK.
TASS news agency reports that books fell from shelves and furniture shook at its headquarters in Tokyo.
No damage was reported at airports, the Japan Times reports, citing officials.
However, NHK claims there was some panic just after the tremors when windows shook at a hotel where a G7 Science and Technology ministerial entourage is meeting ahead of a conference this week.
A 5.6 quake is considered strong according to the Japanese 7-point scale. NHK reports there was no immediate tsunami warning, however.
This comes exactly a month after a devastating quake hit the Japanese city of Kumamoto on the island of Kyushu, with 200 aftershocks rocking the country following the initial tremor of 6.5 magnitude. Forty-nine people lost their lives in the tragedy, with some 110,000 people being evacuated from areas close to the epicenter.
