Tokyo in October

When to go

GO TOKYO's October guide says temperatures gradually get cooler through the month, a light jacket is worth carrying for chilly nights, and visitors should be prepared for the occasional rainy day and on the alert for typhoons. The WMO normals show a mild month with a large monthly precipitation total. Sports Day is a national holiday on the Cabinet Office's list, and GO TOKYO says public holidays bring crowds to popular sights and congestion on roads and public transport, so check your dates against it.
