At least 155 people are dead after heavy rain caused flooding and landslides in western Japan.
It's the worst flooding death toll in the country in over three decades.
More than 70,000 rescue workers are frantically searching through debris to find survivors.
"I have asked my family to prepare for the worst," Kosuke Kiyohara, who has not heard from his sister or her two sons, told AFP.
Settled weather over coming days is expected to help the rescue effort, but with many still missing there are fears the death toll could rise.
Japanese Prime Minister Shinzo Abe has cancelled an overseas trip to deal with the flood crisis.
