Fujikawaguchiko (Mount Fuji) weather in January

A resident's description of a typical January day is the most useful thing on the thread: "the day would start very cold around 0°C, but the continuing sunshine could warm the air up to 10°C" — and if it's cloudy instead, "the temperature would stay around 5°C the whole day." So the sun does the work. What surprises people expecting a grey northern winter is how clear it is: dry air, "no snow and no rain, and even no clouds," completely blue skies. Snow is the exception, not the rule — "it usually won't snow apart from 1–2 exceptional days in January and February" — and rain "can happen, but not often." Wind is described as mild. Long sleeves, a sweater and a coat cover it. Our record agrees on the shape: 8.5°C days, 0.3°C nights, only 6.4 rain days and 7.6 hours of sun.

Fujikawaguchiko's forum is honest that May is a genuine gamble for a clear Mt. Fuji view — cloud tends to hang around the mountain from March through May, and even partial cloud can hide it given its height. Regulars recommend staying flexible and only heading to the lakeside when a forecast looks genuinely clear, since mornings offer better odds than afternoons, when mist tends to build on the upper slopes.
