Damage and injuries weren't immediately clear.
Friday’s quake followed a 7.5 magnitude earthquake earlier this week in the north that caused injuries, light damage, and a tsunami in Pacific coastal communities.
At least 34 people were injured in that earlier quake on Monday off the coast of Aomori, the northernmost prefecture of Japan’s main Honshu island.
