I've read a little about ninjitsu (out of boredom with nothing to do/ so i could rip apart ninja trolls in forums). As far as i can tell 1. Ninja were mecenary spies and assasions. 2. They were considered to be the lowest, most dishonorable group of people in feudal japan. And for good reason. Stabbing people in the back/killing people in there sleep/killing women and children if told to do so/espionage in general was considered to be dishonorable. 3. Traditional ninjitsu is an assasionation art, not a martial art. 4. Ninjitsu is remarably similar to the Navy SEAL training. Unarmed and armed combat is incorperated into the training, but a majority of the training revolves around avoiding confrontation and detection. To answer your questions..no, ninjitsu is not a true martial art. It shouldn't even be considered one. And no, there was no honor in ninjitsu. All of the duties that a ninja would preform were considered to be dishonorable. If you ever meet someone who says they know ninjitsu, don't believe them. As far as i can tell, true ninjitsu dissappeared a long time ago. It got started up again in the 1980's after the movies.... There are a few people today who try to teach ninjitsu, but 99.99999999999% of the time, they're fakes.
