20. Ninjas don’t fight dirty
For being trained assassins, ninjas follow a very serious set of rules. For example, a group of ninjas would never gang up on their victim but rather fight one at a time in order to maintain honor…and not get made fun of by other ninjas for being a wimp.
15. Ninjas wear black (usually)
Ok, so you knew that, but did you know that the uniform they wear is called ashinobi shozoko?
10. Ninjas like to surf
Ok, not really, but they do have some pretty cool ways of getting across bodies of water using various inflatable raft and shoe type devices.
5. Ninjas had clan leaders
As you know, groups of ninjas were called clans. Each clan had a leader and that leader was often the source of numerous legends and statues. Lots and lots of statues.
