Japan in September 2027: Complete Month Guide — Typhoons, Early Autumn, Silver Week

September is Japan's reset month. The last typhoon brings cooler air; red spider lilies bloom; Mt Fuji closes on the 10th; and the second week of Silver Week sends domestic travelers everywhere. The gamble is weather: pick dates in the first week or last week to minimize typhoon exposure, and have a Plan B for a typhoon-locked day.
