Ninjutsu or Japanese martial arts?

[Original TMNT Cartoon Fan]

While practicing Japanese martial arts may be part of ninjtsu techniques, it's easy to end up seing the turtles as just practicing Japanese martial arts combined with some hiding in the shadows and using some old Japanese weapons.

When the UK censored TMNT, they sometimes did a good job replacing words like "Splinter was skilled in ninjutsu" with "Splinter was skilled in Japanese martial arts".

Real ninjas may have used firearms, something the turtles usually use just on their van. (even if fictional ninja may be based on a combination of real ninjas, and the myths about them)

So, do you care much for all aspects of the "ninja", or are you fine with the turtles using "Japanese budo" (karate chops and judo swings) and hiding in the shadows and using Japanese martial arts.
