Traveller notes on Fujikawaguchiko in May
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.
