More than 100,000 flee floods in Japan after 'once-in-50-years' rain
Unprecedented rain in Japan unleashed heavy floods on September 11 that tore houses from their foundations, uprooted trees and forced more than 100,000 people from their homes.
Helicopters hovering over swirling, muddy waters rescued many people from the roofs of their homes. Seven people were missing and at least 17 were injured, one seriously.
Some areas received double the usual September rainfall in 48 hours after tropical storm Etau swept across Japan's main island of Honshu. In some places, rain-swollen rivers burst their banks.
A 63-year old woman was missing in a landslide that hit her home while a man in his 70s in the town of Joso, 56 km (35 miles) north of Tokyo, was feared trapped when water engulfed his home, NHK national television said.
Television broadcast footage of helicopters winching people to safety, including an elderly couple clutching a pair of struggling dogs as the flood tore away pieces of their home.
A further 800,000 people were at one point advised to evacuate after officials issued predawn warnings of "once in a half century rains" to 5 million people in areas east and north of Tokyo.
Japan has put heavy emphasis on disaster prevention since a 2011 earthquake and tsunami killed nearly 20,000 people and authorities are keen to avoid the kind of criticism they faced then, for what was seen as a sluggish response.
The government set up an emergency center, and Prime Minister Shinzo Abe told a meeting of ministers that the "unprecedented" rain had created an emergency.
Up to 12 military helicopters took part in the rescue along with an initial 55 members of Japan's military, the Self Defence Force. Officials said their number would rise.
Rescue workers rushed to find people before nightfall.
Part of a hotel in the town of Nikko, famed for its shrines and temples, had collapsed, Kyodo news agency said, but there were no reports of injuries.
Rainfall reached 500 mm (20 inches) around Joso, NHK said, with weather officials expecting at least 200 mm (8 inches) more in parts of eastern Japan, including Fukushima, the site of the nuclear reactor crippled in 2011, before the downpour stops on September 11.
