Traveller notes on Yakushima in October
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.
