A newly released satellite image from Europe’s Copernicus Earth observation program offers a striking look at the extraordinary winter Japan has been experiencing—one defined by record-level snowfall. Captured on February 10 by a Sentinel-2 satellite, the image shows Niigata Prefecture along the Sea of Japan coast almost entirely buried beneath snow. Cities, farmland, and surrounding mountains are visible only as faint shapes under a vast white blanket, illustrating just how extreme accumulation has become after weeks of relentless storms.
According to Copernicus, Japan has been dealing with record-breaking snowfall since late January 2026. The prolonged snow cycle has led to major nationwide impacts, including dozens of deaths, hundreds of injuries, transportation shutdowns, and extensive damage to infrastructure. Much of the danger has come not only from the depth of the snow itself, but from secondary risks such as avalanches, roof collapses, and hazardous cleanup conditions.
Niigata, located roughly 300 kilometers northwest of Tokyo and historically known for heavy snowfall, has been among the hardest-hit regions this season. Persistent storm tracks moving off the Sea of Japan have repeatedly dumped large amounts of lake-effect-style snow across the prefecture’s coastal plains and mountainous terrain.
Copernicus says satellite monitoring plays a critical role during winters like this. By mapping snow extent and tracking how long it persists on the ground, the data helps authorities evaluate impacts, anticipate hazards, and improve preparedness during extreme weather events.
The winter in Japan has been exceptional. From space is visible a near-continuous white expanse stretching from coastline to high alpine terrain, clearly showing how Japan is having one of the most intense snow seasons in recent memory.
