Number rose after officials in Atami checked residential registers rather than relying on reports of missing people following mudslide

Officials in Japan have dramatically raised their estimate of the number of people still missing after a mudslide ripped through a seaside town at the weekend.

Reports said three people had died in the disaster, which occurred after days of torrential rain in Atami, a famous hot spring resort about 60 miles (90 km) south-west of Tokyo.
