Traveller notes on Yakushima in April
Other months in Yakushima
Yakushima's forum flags October as still within typhoon season, which can run through late in the month, and warns that heavy rain — not unusual on this famously wet island — can shut the trails and turn the rivers dangerous. Regulars still rate it among the best hiking months when the weather cooperates, so it's worth building a flexible day or two into the plan.
