As robyng mentioned, most of the temples close at around 5 or 6, and stop letting people in slightly before then, but assuming you're not delayed, you should be able to squeeze in one of the ones close to your hotel the day you arrive.

Also, several of the temples in Kyoto are as they say in Japanese, "light up," where they're night lit, and reopen from around 7-10 at night. Probably easiest to get a recommendation from your concierge when you arrive, but I went to Kyomizadera after dark when I was in Kyoto a couple of weeks ago, and it was crowded, but very cool at night and very different than during the day.

When I was there last fall, I went to a different, much smaller and less crowded, temple at night, and that was also very memorable as you were given a paper lantern with candle to carry as you walked around the grounds. I can't remember the name of that temple right now, but the first Kanji in it's name means blue and it's quite close to Gion. It wasn't open at night a couple of weeks ago, but was going to be reopening again sometime soon.
