Northern and western regions of Japan were hit by heavy snowfall last week. Major traffic disruptions were reported in various regions and multiple flights were cancelled. Supply routes and train services have also been affected.
Most of the injuries reported amid the record snowfall occurred due to falls, while reported deaths predominantly happened as people tried to clear rooftops of snow. Over this winter, Japan’s central and northern regions have seen record snowfall, several times above the norm.
