Ninjutsu by its very nature is a methodology that is centered in the here and now, developed to reveal the most applicable approach to any given situation. In real life, every situation is different, so Ninjutsu, unlike many other martial arts, does not draw from a predetermined set of reactions. Ninjutsu is about learning to understand, see, and truly feel the way to adapt and react to situations, using guidance from basic fundamental concepts of Budo Taijutsu. Given this approach, Ninjutsu changes constantly to adapt to the needs of the contemporary battlefield, be it in body armor, in street clothes, or in a business suit.
