Japan struggled on Tuesday to restore utilities after its worst weather disaster in 36 years killed 176 people, with survivors facing health risks from terrible temperatures and a lack of water.

Reports say agencies have kept up a grim search for survivors and corpses of the dead after last week’s heavy rains in western Japan, even as the country’s Prime Minister, Shinzo Abe is expected to visit the ravaged city of Kurashiki.

Chief Cabinet Secretary, Yoshihide Suga said on Wednesday that Abe would visit an evacuation centre in Kurashiki, a city where a river broke through an embankment and swept through residential areas, killing more than 40 people.

Tens of thousands of rescue and recovery workers and volunteers are digging through the debris, as the search for dozens still missing enters its fifth day.

The unprecedented rainfall caused severe flooding and landslides, toppling and burying homes across a wide area. Most of the deaths were recorded in Hiroshima and surrounding areas.
