A magnitude 7.3 earthquake struck off the Fukushima region of Japan, according to the U.S. Geological Service.
The epicenter was located 295 miles east northeast of Tokyo and 231 miles east of Japan's Honshu Island.
The Japan Meteorological Agency issued a tsunami advisory for the east coast of Japan, including the Fukushima Prefecture.
"Marine threat is in place," the agency warns. "Get out of the water and leave the coast immediately."
The agency said it expects a slight sea level change in coastal regions, but no tsunami damage.
NOAA's Pacific Tsunami Warning Center said the quake was not expected to trigger a Pacific-wide tsunami and that there was no threat to Hawaii.
