0 
A series of aftershocks rattled Japan Thursday after the magnitude 7.3 tremor hit the northeastern Honshu island the previous day, the Japan Meteorological Agency said.
A strong aftershock with a preliminary magnitude 6.6 hit northeastern Japan at 6:24 a.m.. There were no immediate reports of injuries or damage from the quake.
The weather agency temporarily issued a tsunami warning for the Pacific coast of adjacent Fukushima Prefecture after the quake but was soon lifted.
East Japan Railway Co. said the quake did not affect Shinkansen bullet trains linking the Tohoku region and Tokyo on Thursday morning, according to local media reports.
The strong aftershock came three hours after a magnitude 6.2 quake and another one measuring 6.1. Wednesday's quake and the early Thursday's aftershocks were all in the same area.
Japan is one of the countries most frequently hit by earthquakes. Around 20 percent of the world's most powerful earthquakes strike Japan.
