Ninjutsu? Did you practice horsemanship, espionage, or impersonation? I'm serious (https://en.wikipedia.org/wiki/Ninjutsu#The_eighteen_skills). Were live horses and stables involved? Were there method acting lessons? How did this work?

I can imagine a complete school would be fascinating, rare (given the amount of land required) and quite an achievement. Is there an organization analogous to say Hombu (http://www.aikikai.or.jp/eng/information/ ... essentially the Vatican City of Aikido)?
