A powerful earthquake struck off the coast of northern Japan on Friday, the weather office said, days after an even larger tremor shook the region and injured at least 50.
The Japan Meteorological Agency (JMA) upgraded Friday's quake to a 6.7 magnitude and warned that tsunami waves of up to one metre (three feet) could hit the northern Pacific coastline.
Two 20-centimetre waves had so far been recorded, one in the town of Erimo on the main northern island of Hokkaido at 12:35 pm (3:35 GMT), and another three minutes later in the Aomori region, the agency said.
