September weather in Tokyo — FAQ
Q. Is September already cool in Tokyo?

Q. Will a typhoon completely ruin my schedule?
A. Direct impact days can disrupt outdoor plans, but intense conditions typically last only a day or two. Viewing one or two days as “rest and indoor days” can make the overall trip feel smoother.
