Right now I'm currently working on a short novel - hopefully to be finished in the near future - that is based in a typical Japanese High School setting when all of a sudden I realized that the most important part (the opening to it) needs the Entrance Ceremony and I know close to nothing of that.

So I'm asking those that do know:

Does school start later on that day? Do the upper Classmen go to their homeroom first or the ceremony first as my characters are mainly all upper class?

Much thanks to whomever answers, it will be a real lifesaver!
