Tokyo: A massive storm system dropped feet of snow on parts of Japan this week, leading to travel problems and killing up to 11 people.

The winter snow storm gripped much of Japan, while forecasters on Friday warned bad weather would continue.

Northern and central parts of Japan have been lashed by strong winds that have dumped huge quantities of snow over the last few days, disrupting travel and cutting off isolated communities.

The Yomiuri Shimbun newspaper said 11 people were known to have died, including two people - a 79-year-old man and a fire fighter, 29, who fell into ditches while clearing snow.

Several other, mainly elderly people have been killed on the northernmost main island of Hokkaido and in regions near the Sea of Japan (East Sea) in mainland Honshu, reports and officials have said.

There have also been deaths on the roads, with hazardous driving conditions provoking hundreds of accidents that have left dozens injured nationwide.

Public transport networks have also been hit, with several hundred flights grounded, most of them domestic, and bullet trains suffering delays.

More than 270 people were stranded in mountainous areas of Niigata and Nagano after the only road linking them with the outside world was blocked by an avalanche, reports said.

The Japan Meteorological Agency (JMA) was warning of the risk of further avalanches across much of the country.

Strong winds gusting at up to 140 kilometres (87 miles) an hour have also caused tidal surges and people in coastal areas were being warned of the danger of high waves.

The storm, which was caused by a powerful area of low pressure "has now peaked, but snow is continuing in regions by the Sea of Japan," the JMA said.

More than 200 centimetres (79 inches) of snow was already lying in some areas, with more forecast.

Weather.com meteorologist Jon Erdman said that Tsunan, Japan, saw a snow depth of 81.5 inches (207 centimeters).

"Seven other locations in western Honshu reported at least 150 centimeters (about 59 inches) of snow depth, according to the Japan Meteorological Agency."

The fatality in Hiroshima occurred when a driver got out of his car and was hit by another vehicle, NHK said.

Flights grounded

Travel was also affected by the big storm, both in the air and on the ground. Some 550 flights have been canceled Wednesday and Thursday, News Australia reported, and dozens of cars were stuck underneath huge snow drifts on city roads.

"The current sea-effect snow event should wind down by Friday," said Erdman.

"However, another strong frontal system this weekend could reactivate the sea-effect snow machine in Japan through Monday. Snow cover by early next week could be very impressive in the most typically hard-hit sea-effect areas."
