The Bujinkan (武神館) is an international martial arts organization based in Japan and headed by Masaaki Hatsumi. The combat system taught by this organization comprises nine separate ryuha, or schools, which are collectively referred to as Bujinkan Budō Taijutsu. The Bujinkan is most commonly associated with ninjutsu. However, Masaaki Hatsumi uses the term Budo (meaning martial way) as he says the ryuha are descended from historical samurai schools that teach samurai martial tactics and ninjutsu schools that teach ninja tactics.
Bujinkan Budo Taijutsu training does not include participation in competitions or contests, as the school's training aims to develop the ability to protect oneself and others using techniques that focus on disabling an attacker (&/or removing their desire/ability to continue) as efficiently as possible.
The Bujinkan does not adhere to any official guideline or set of rules to limit actions or techniques used during training. The approach used in the Bujinkan includes gaining compliance through pain and utilising potentially damaging techniques in order to survive dangerous situations rather than focusing on winning a competition or evenly matched duel. As a result, many of the staple responses of a Bujinkan student would be inappropriate in most competitions
Training is conducted in a safe and friendly manner, and though there is no competetive side of the art as such, this does not mean the techniques are untested. As skills increase, the effectiveness of technique is increased.
Having been tested many times, for real, in high risk situations, with multiple attackers and at times armed attackers, I am testament to the validity of the training and security awareness the Bujinkan has bestowed upon me.
In reality !
there are no rules
there is nobody to stop the fight when it gets out of hand or there is serious injury
most fights last seconds
there are no mats
there is a risk of weapons
there may be more than one attacker
you are not fighting for points or trophies, you are fighting to stay safe and stay alive
