I have to write a paper for my japanese history class( not long about 5 pages). I can choose any subject which has to do with japanese history ( from mythology to World War 2) but here's the catch, it has to be original. And every idea I've had so far has already been used last year. Does anybody know any subjects?

( The Kensei seems like an interesting subject but I doubt that if I will be able to find a lot about them)
