A magnitude 6.2 earthquake shook Japan's northernmost main island of Hokkaido on Sunday, but there were no immediate reports of damage or injuries.
No tsunami warning was issued. There were no reports of problems at the nuclear plants in the area, or of disruptions to power supply or bullet trains running in northern Japan.
