Strong typhoon winds lash Tokyo area

One of the strongest typhoons to hit the Japanese capital in recent years made landfall just east of Japan's capital, with record-breaking winds, stinging rain and raising rivers before heading out to sea.

More than 130 flights were cancelled and scores of train lines were closed for hours on Monday, snarling the morning commute for millions in a greater Tokyo area that has a population of some 36 million.

Typhoon Faxai slammed ashore in the city of Chiba, just east of Tokyo, a little before dawn, bringing with it wind gusts of 207km/h, the strongest ever recorded there, national broadcaster NHK said.

There were no immediate reports of deaths and only one serious injury, a woman in her 20s who had to be rescued from her house after it was partly crushed when a metal pole from a golf driving range fell on it.

Some minor landslides occurred and a bridge was washed away, while as many as 930,000 houses lost power at one point, NHK said, including the entire city of Kamogawa.

"I've never seen a situation like this, the whole city without power," an official told NHK.

The storm had headed out to sea by midmorning, but authorities warned that heavy rains were likely to continue for some hours, including in Fukushima, the site of the world's worst nuclear disaster since Chernobyl.

NHK said Faxai was the strongest storm in the Tokyo area in several years.

Metal signs were torn from the sides of buildings, trucks overturned, the metal roof of a gas station torn off and glass display cases destroyed, scattering sidewalks with broken glass.

Trees were uprooted throughout the metropolitan area, some falling on train tracks to further snarl transportation.

Some 2,000 people were ordered to evacuate because of the danger of landslides, NHK said, but there were no immediate reports of major damage.

Around four to five typhoons make landfall in Japan every year, but it is unusual for them to do so near Tokyo.
