History is so amazing. Who knew what happened years and years ago are relived often times in museums and even in cities! One city in Japan has such a rich history of ninjas that the they even have a festival that lasts 5 weeks just on ninjas. Performances, training courses and even ninja costume rentals for people as well as animals. How fun is that.
