Rescuers are digging through mud, trying to find dozens who are missing after a mudslide in Atami, Japan.

At least four are dead and 80 are missing.

Days of heavy rain in the seaside town brought the wave of mud, ripped up trees and rocks.

Atami, like other Japanese towns is built on hillside.

With more parts of the country expecting heavy rain, authorities are urging caution to everyone near a hillside.
