The Kansai is generally pretty warm and Osaka is roughly the same latitude as the border between North and South Carolina. Osaka stays warm into November, but doesn't really warm up until late May. Summers are really hot, Spring is nice but brisk, Winter is cold but there's little snow, and Fall is the nicest time of year. - Oct 2013
