Heavy snowfall affecting Japan since late January 2026 has left at least 46 people dead and more than 550 injured while causing widespread agricultural damage across the Tohoku region and Niigata Prefecture. Snowfall reached 148 cm (58 inches) in Hirosaki, Aomori Prefecture, in January, breaking branches in apple orchards, collapsing vinyl greenhouses, and burying farm roads that remain inaccessible in some areas. Authorities say the full extent of agricultural losses may not be known until snow cover recedes.
