Mount Fuji receives substantial snowfall each winter, creating its famous white cap. At the summit (3,776 m), the average annual snowfall is 3–4 meters (10–13 feet), while lower elevations see 1–2 meters (3–6 feet).
The heaviest snow falls from December through February, driven by cold Siberian air masses picking up moisture over the Sea of Japan. Snowpack persists into early summer, feeding rivers and lakes that supply water for agriculture, industry, and millions of people in the surrounding prefectures.
Year‑to‑year totals vary with temperature, humidity, and wind patterns. Warmer winters can reduce accumulation, affecting downstream water availability. Monitoring Fuji's snowpack is crucial for regional water‑resource planning.
