Residents of south west Japan have a sad story to tell.

Most of them were rendered homeless while a 93-year-old man was washed up after the area was flooded during a downpour.

Police say they found the 93-year-old man washed up dead Wednesday. They believe he was swept away in flooding in Asakita in Hiroshima prefecture.

Media reports say more than 20,000 people in Fukuoka prefecture were advised to evacuate. The Japan Meteorological Agency says there has been a record amount of rain in the prefecture, telling residents to be vigilant and take precautions.

Heavy rain continued in southwestern Japan late Wednesday, threatening to bring landslides and more flooding.

Typhoon Nanmadol brought heavy rain and flooding across the country this week as it moved eastward.
