Dozens missing after torrential rainfall in Japan's southwest

More than 7,800 rescuers are searching for missing and stranded people

Japan CNN  — 

At least 18 people were killed and hundreds are still stranded after heavy rains triggered floods and landslides this week in southwest Japan, according to Japanese state-run NHK news agency.

Fifteen people died in Fukuoka and three in Oita Prefecture. An evacuation order remains in effect for nearly 105,000 people.

Heavy rains hamper search efforts

Aerial television footage shows how rivers overflowing with water ripped through swathes of land, toppling houses and sweeping away roads.

Collapsed houses are half-buried in  mud following the flooding caused by heavy rain in Asakura, Fukuoka prefecture, southwestern Japan.

More than 7,800 rescuers from the Fukuoka police force and Japan self defense forces have been working around the clock to search for missing people. But heavy rain Friday hampered their efforts, making rescue operations treacherous as they battled against thick mud and debris.

“When we get this amount of rainfall in a short amount of time it takes a lot of debris with it … Debris fields inundate whole houses and communities,” CNN’s meteorologist Derek Van Dam said.

Earlier this week, Asakura experienced more than one and a half times its monthly average rainfall in a period of 24 hours. Asakura normally receives 354 milimeters (14 inches) per month, but on Wednesday received up to 525 milimeters (20.6 inches).

More rains are expected as the monsoonal season continues to impact east Asia. An additional 50 milimeters (2 inches) of rainfall could lead to more landslides in Fukuoka.

Emperor Akihito’s eldest daughter, Princess Mako, decided to postpone the highly-anticipated engagement announcement to her fiance out of consideration to those in the disaster-hit region, according to a statement released Friday by Japan’s Imperial Household Agency.
