Weather officials say heavy snow will continue falling through Monday morning in coastal areas along the Sea of Japan.
The Meteorological Agency says a strong winter pressure pattern and a mass of very cold air have dumped a large amount of snow, mainly in the Hokuriku region and Niigata Prefecture.
As of 6 p.m. on Sunday, 233 centimeters of snowfall had been recorded in the city of Joetsu, Niigata Prefecture, 115 centimeters in Toyama City, 103 centimeters in Fukui City, and 59 centimeters in Kanazawa City, Ishikawa Prefecture.
The amount of accumulated snow was more than double the average amount for this time of the year at most observation points in the prefectures of Niigata, Toyama, Ishikawa and Fukui.
Fukui City had more than 100 centimeters of snow for the first time since February 2018.
In Niigata and Hokuriku, the snow will intensify intermittently through Monday morning. It will accumulate in some areas to a level where clearing the snow becomes difficult.
Weather officials are urging caution for icy roads, avalanches and snow on power lines triggering blackouts. The officials say another low-pressure system near the Noto Peninsula, Ishikawa Prefecture, will make atmospheric conditions unstable through Monday morning, and warn there could be gusty winds and lightning strikes.
