They should be played by Japanese men. BTW if they are Japanese women they are exactly the same except they are called Kunoichi. Okay that was probably to much, let’s just stick with Japanese people. I’m tired of seeing ninja movies with white guys. It’s like seeing a movie called, English Bobby, and it only features Ninjas! Wait…that would be great.
