Tokyo: Desperate relatives braced for bad news Monday as rescuers dug through landslides in the wake of severe floods that have killed 100 people and left swathes of central and western Japan under water.
As floods receded, emergency workers were able to reach previously cut-off places where authorities fear they could find more bodies in the wreckage of homes devastated by rivers of mud and debris.
"I have asked my family to prepare for the worst," said Kosuke Kiyohara, 38, as he waited for word of his sister and her two young sons.
"I can't reach her phone," he told AFP, sitting across from a house that had been ripped apart and tossed on its side by a huge landslide.
At the end of last week rivers engorged by more than a metre (three feet) of rain burst their banks, engulfing entire villages and forcing people to rooftops to await evacuation by helicopter.
Hillsides gave way under the weight of water, with deadly landslides crushing wooden houses and erasing roads.
On Monday morning, with the sun finally out and temperatures rising, rescue workers dug through mud in a desperate search for survivors, or victims.
The government said at least 100 people had been killed, and with many people still missing, the tally was expected to rise further.
Search for survivors
"A total of 73,000 police, fire department, Self-Defence Forces and Japan Coast Guard personnel, with 700 helicopters, are doing their best as part of the rescue effort," government spokesman Yoshihide Suga said.
In Kumano, soldiers and other emergency workers were using diggers to clear crushed cars and mangled homes.
But they were moving carefully, looking as they went for survivors, or the remains of those killed in the disaster.
In one part of Kumano, the nose of a white car was just visible underneath the top floor of a home that had been torn from the rest of the building and swept down a hillside.
Much of the road that once led into the upscale district of a town known for brushmaking was no longer visible, and water was still flowing from the surrounding hillsides around the feet of shellshocked residents.
In neighbouring Okayama prefecture, rescue workers flew in helicopters over areas that are still submerged and otherwise unreachable, looking for signs of life.
"As far as we could see from the helicopter, no-one is now waving for help," a rescue worker from Kurashiki city told AFP.
Local government officials said pumping trucks were being deployed to help restore access to some of the worst-hit areas.
"Rescuers had to go by boat yesterday due to flooding but the water is gradually receding today," a spokeswoman at the area's disaster control office said.
"If the water level drops low enough, they may be able to access hard-hit areas by road or on foot."
Even as the rains let up, authorities warned the downpours had loosened earth on hillsides and mountain slopes creating new risks.
"We urge residents to remain cautious about possible landslides," a weather agency official told AFP.
And with many people stuck in modestly equipped shelters with few possessions, or living in damaged homes with no running water or electricity, the rising temperatures posed a new problem, authorities said.
At one point around five million people were told to evacuate, but the orders are not mandatory and many people remained at home, becoming trapped by rapidly rising water or sudden landslides.
In the town of Mihara, roads were transformed into muddy rivers, with dirt piled up on either side as flood water gushed around the wheels of stranded cars.
"The area became an ocean," 82-year-old resident Nobue Kakumoto told AFP Sunday, surveying the scene.
In the town of Saka, Eiichi Tsuiki opted to stay in his home, and survived only by moving to the top floor as flood waters rose, washing away cars outside.
"I've lived here for 40 years... I've never seen this before," the 69-year-old oyster farmer told AFP.
