I'm going to be in Japan for a work trip next week and I was considering staying in-country and doing some sightseeing afterwards. The dates I could stay would be Friday 11/22 - Tuesday 11/26. I know that weekend is a holiday, but I'm not sure how that will affect the crowds or my enjoyment while there. Is it going to be a zoo in Osaka/Kyoto? I know there aren't too many hotel rooms available, so that will be a consideration as well.
Any advice would be much appreciated!
