Original report, 06 July 2017
Parts of southern Japan were hit by flooding and landslides after heavy rain in the wake of Typhoon Nanmadol which swept through the area earlier this week.
Over 50 cm of rain fell in Asakura, Fukuoka prefecture, in a 9 hour period on Wednesday 05 July 2017.
Authorities said that over 440,000 people across the country were under urgent evacuation instructions. Most of the evacuations orders were for areas of Fukuoka prefecture.
Teams from Japan’s military and emergency services, including several helicopter crews, are scrambling to evacuate hundreds of people who remain trapped and assess the full damage of the flooding.
At least 1 fatality has been confirmed by authorities. Some media reports claim that at least 2 people have died and 18 people are missing.
In a press conference today (06 July) Yoshihide Suga, Japan’s Chief Cabinet Secretary, said that there are conflicting reports on the numbers of missing people and refused to confirm figures until further assessments had been carried out.
Fukuoka and Oita
Japan’s Fire and Disaster Management Agency (FDMA) said that the torrential rain in Fukuoka and Oita prefecture is unlike anything experienced before.
FDMA confirmed that a man had died in a landslide near Hita in Oita prefecture. Two other people were rescued from the landslide. In total, five people have suffered injuries in the two prefectures.
Dozens of houses in Fukuoka and Oita have been damaged, with at least 5 in Fukuoka and 1 in Oita completely destroyed.
Residents in one community in Asakura, Fukuoka, have been isolated after rivers in the area overflowed.
FDMA said that almost 400,000 people were under urgent evacuation instructions in Fukuoka, with 306,000 in Kurume, 54,000 in Asakura and 18,000 in nearby Chikuzen district.
Kurume avoided particularly heavy rainfall yesterday (around 10 mm), but has so far today recorded over 100 mm (as of 19:00 hrs local time, 06 July). However, river levels increased dramatically, prompting the evacuation orders.
Shimane and Hiroshima
Rain and flooding has also affected Shimane and Hiroshima prefectures. Local media reported that the body of a man was found in a river in Hiroshima and local police believe he was swept away as the river level rose during torrential rain.
As many as 50 families have been left isolated by flood waters and landslide damage in several parts of Shimane.
Over 200 homes have been damaged across the country as a result of severe weather over the last few days according to FDMA, including 51 in Niigata Prefecture.
According to Japan’s Foundation of River and Basin Integrated Communications (FRICS), several rivers in Fukuoka and Oita were flowing above the danger mark, including the Chikugo, Yamakuni, Oita, Nanase and Hikoyama. FRICS figures suggest that all river levels have since fallen to below the danger mark.
In Asakura 516 mm of rain fell was recorded for a 24-hour period on 05 July. In fact around 500 mm fell between 12:00 and 21:00 hrs on 05 July, with 106.0 mm of rain falling in just 1 hour between 16:00 and 17:00.
Hita in Oita prefecture recorded 336 mm of rain in 24 hours on 05 July.
