Tohoku Electric Power Co has halted the Onagawa nuclear plant and is checking for any irregularities, NHK said.
Tokyo Electric Power said it is checking the condition of the Fukushima Dai-Ichi power station that was wrecked by the massive March 2011 quake, which caused nuclear meltdowns and mass evacuations.
NHK showed footage from inside its Sendai bureau showing a plaque suspended from the ceiling shaking for about 30 seconds following the tremor. It did not report any items falling from shelves or any immediate damage.
The quake could be felt in Tokyo about 400 kilometer south of the epicenter.
NHK warned the public against coming anywhere near the shore.
