Below is a link you might find helpful. In my experience, early November in Tokyo can be quite nice - I have been comfortable in short-sleeves and a light sweater in my daypack. Later in the month will be cooler but still nice. Maybe long-sleeves with a light jacket available. Late November will be "fall color" time, similar to New England in the Fall. Early December will be cool and dry but rarely cold. November/December is a pretty good time to visit Tokyo and Kyoto.
