The worst snowfall to hit Tokyo in decades caused major disruptions to power, thousands of injuries and at least 11 deaths.

Japan’s Meteorological Agency said over 10.6 inches of snow fell by late Saturday, the most to fall on the city in 45 years.  Commuters on Monday morning found that most roads had not been plowed and many areas outside the downtown area were impassable from blowing snow.

Flights at Tokyo’s Haneda International Airport were cancelled or backed up with remaining flights overbooked with people attempting to leave.  Officials said at least 5,000 people were stuck at the airport.

Power was out for over 20,000 households.

Officials say 11 people died from car accidents or falls.  At least one man was reported in critical condition after falling after he slipped while shoveling snow.  Officials did not say how many of the 1,000 reported injuries required a hospital stay.

In the northern part of the country, the city of Sendai which had been partially devastated by the 2011 tsunami recorded almost 14 inches of snow, the highest level in 78 years.
