TEHRAN, Young Journalists Club (YJC) - Nearly, 2 million people live in Osaka, the second city of Japan.
On of the killed people was a nine-year old girl. The other two dead were an 80-year-old man and a man trapped under his home bookcase, local media sources said.
The destruction left by the quake, of course, was not of a large scale.
The Fire and Disaster Management Agency also affirmed that more than 200 people were injured.
A government spokesman Yoshihide Suga cautioned there was a possibility of strong aftershocks.
Japan's Prime Minister Shinzo Abe also announced that saving people's lives in on top of government priority.
Japan sits on the Pacific "Ring of Fire" where many of the world's earthquakes and volcanic eruptions are recorded.
On March 11, 2011, a devastating magnitude 9.0 quake struck under the Pacific Ocean, and the resulting tsunami caused widespread damage and claimed thousands of lives.
It also sent three reactors into meltdown at the Fukushima nuclear plant, causing Japan's worst postwar disaster and the most serious nuclear accident since Chernobyl in 1986.
