Day 1 - "Intro to World Heritage"
If you had just one day in Nikko, you could see a lot. Maybe even be able to see most of this big items. For my money, I can't think of any other place in Japan with so much good stuff packed into a small-ish place. Thus, I broke up the big highlights of Nikko into multiple days. Today, you get more than a little taste. This city is just epic.
