Houses dramatically washed away as Japan hit by massive floods
Military helicopters have plucked residents from the top floors of their homes after floodwaters inundated a city north of Tokyo.
As heavy rain pummelled Japan for a second day, the Kinugawa River broke through a flood embankment, sending a wall of water into Joso, about 30 miles north east of the capital.
National broadcaster NHK showed aerial footage of rescuers being lowered from helicopters and clambering on to second-floor balconies to reach stranded residents.
One rescuer descended four times over a 20-minute period to take four people up one-by-one, as a deluge of water swept around the home.
Others waved cloths from their homes as torrents of water around them washed away cars and knocked buildings off their foundations.
Elsewhere in the region, one woman was missing hours after a landslide hit houses at the foot of a steep, wooded incline. Bullet train services were partially suspended.
Tokyo was also drenched with rain, but the hardest-hit area was to the north in Ibaraki and Tochigi prefectures.
The rain came on the heels of Tropical Storm Etau, which caused similar flooding and landslides on Wednesday as it crossed central Japan.
The Fire and Disaster and Management Agency said 15 people were injured by Etau, two seriously, both elderly women who were knocked over by strong winds.
