A magnitude 7.2 earthquake struck near the east coast of Honshu, Japan on Saturday, the GFZ German Research Centre for Geosciences said.
Japan public broadcaster NHK warned residents a tsunami of one meter was expected for Miyagi Prefecture.
The quake hit at 6:09 pm (0909 GMT) local time in Pacific Ocean waters off Miyagi region with a depth of 60 kilometers (37 miles), the JMA said, issuing an advisory for tsunami waves of around one meter.
The warning stated: ‘It is dangerous in the sea or near the coast. Those who are in the sea should immediately get out of the sea and leave the coast.
‘The tide will continue to be fast, so please do not enter the sea or approach the coast until the warning is cleared.’
The warning also said that it was expected that there would be ‘slight sea fluctuation’, and that in some places the tsunami may be higher than ‘expected tsunami height.’
‘It was a really bad, long shaking from side-to-side. It was even longer than the quake last month, but at least the building here is all right,’ Shizue Onodera told Japan broadcasting company NHK from the shop where she works in the city of Ishinomaki.
