Top Japanese government spokesman Yoshihide Suga on Monday confirmed the deaths of a child and a man, and said a third person was also feared dead in the quake. The quake knocked over walls, scattered goods on the floor of shops and set off scattered fires around Osaka.
The Japan Meteorological Agency is warning that over one week there may be aftershocks that have around the same seismic intensity as Monday's quake, which registered lower 6 on the Japanese scale of 7.
No irregularities were detected at the Mihama, Takahama and Ohi nuclear plants to the north of Osaka, Kansai Electric Power said.
Disaster Management Minister Hachiro Okonogi says there are reports of people being buried under collapsed buildings.
Although largely unaffected by the powerful quake, Chan said groups may need to adjust their itineraries. "Almost all of the dishes fell and shattered on the floor", said Kaori Iwakiri, a 50-year-old nurse in Moriguchi, just north of Osaka city.
Television footage also showed a "shinkansen" bullet train stopped on the railway.
The vehicle manufacturer Daihatsu said it had suspended operations at its plants in Osaka and nearby Kyoto, while the consumer electronics firm Sharp said its factories were operating normally.
Honda Motor Co. and Mitsubishi Motors said they were resuming operations after suspensions and safety checks. Bloomberg reported plants across the area were halted as firms assessed the damage. "I thought it was a nightmare because I was so confused", she said.
"We will investigate the cause of (the collapse of the wall) and sincerely address (the concerns of) her parents", he said.
The inland quake did not trigger a tsunami and no nuclear power plants in the vicinity reported abnormalities, but dozens of fires were reported in Osaka, Hyogo, Kyoto and Mie prefectures, according to local authorities.
"It was not as bad as the Kobe quake", he told the Associated Press from Osaka.
