Snow has begun to accumulate in southern parts of the Kanto region, including Tokyo today. Weather officials say a cold air mass and pressure trough have produced intermittent snow since early morning.
At 9:00 am, the snow on the ground in the city of Chiba was five centimeters deep. It was two centimeters in Tsukuba in Ibaraki prefecture, NHK reports.
By the end of the day central Tokyo could get a centimeter of snow. The Kanto plains could get seven centimeters. Mountainous areas could get five centimeters.
Weather officials are urging people to be ready for slippery roads and traffic disruptions.
They are also cautioning people to look out for snow building up on power lines and the branches of trees.
