MINAMIASO, Japan — The U.S. military prepared to join relief efforts Monday in disaster-stricken areas of southern Japan as authorities struggled to feed and care for tens of thousands of people who sought shelter after two powerful earthquakes that killed at least 42 people.
Ten people remained missing, and rescuers were redoubling search efforts on the southern island of Kyushu, where many areas were cut off by landslides and road and bridge damage. Forecasts for heavy rains, which would make land and collapsed buildings even more unstable, added to the urgency of the searches.
Toyota Motor Corp. said it would shut down most of its vehicle production in Japan over the course of this week because of parts shortages stemming from the earthquakes. Nissan Motor Co. also halted production at some facilities.
With 180,000 people seeking shelter, some evacuees said that food distribution was a meager two rice balls for dinner.
“We are doing our best,” Prime Minister Shinzo Abe told lawmakers when challenged by the opposition over the government’s handling of the relief effort.
“This is the way it is. Today, tomorrow, the day after tomorrow, we will be working toward a full recovery,” Abe said.
U.S. Forces, Japan said troops were preparing to provide aerial support for Japan’s relief efforts.
Many whose homes were not seriously damaged sought shelter as the area was rocked by more than 500 aftershocks from two big quakes that struck late Thursday night and in the early hours of Saturday.
“Without water and electricity, we can’t do anything. Without the TV on, we can’t even get information about disaster relief operations,” said Megumi Kudo, 51.
