Local fishermen in several ports in the area said an around 10 centimeter tsunami struck Iwate Prefecture, according to Japanese reports.
The Japan Meteorological Agency (JMA) had advised evacuating the coastal areas there.
The tsunami warning in the area has been cancelled, the JMA said.
“Though there may be slight sea-level change in coastal regions, no tsunami damage is expected,” the JMA said on its website.
Iwate Prefecture is largely rural, with a total population of around 1.3 million. While the area has a nuclear power plant, it was not damaged, according to a report.
