Traveller notes on Fujikawaguchiko in September
Notes from nearby Tokyo (87 km away)
Fujikawaguchiko doesn't have its own notes for September yet — these are about Tokyo, close enough to share the season.
September looks decent and is a gamble: the first half is still summer humidity, and typhoon season peaks now. I've had a perfect week and I've had two days indoors watching trains cancel. Late September is safer than early.
Other months in Fujikawaguchiko
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.
