A word of caution on illuminations at horse racing tracks. I used to live near one outside Tokyo and they are frequented by a rather unsavory group of people who sometimes pick fights with people. It may be less of a problem at night when there's no racing but frankly, I'd stick to the non-race track illuminations, which unfortunately tend to be a boring monochrome, usually blue or white with no Christmassy colors like red or green at all.
