Kinjutsu is a traditional Japanese martial art that focuses on the use of forbidden techniques or strategies. The term translates to "forbidden techniques," and it often involves practices that are considered unethical or dangerous. Kinjutsu is typically associated with the darker aspects of martial arts, emphasizing stealth, deception, and psychological warfare. Practitioners of Kinjutsu may study various forms of combat, including the use of weapons and unarmed techniques. While it is not as widely practiced as other martial arts, it holds historical significance in the context of Ninjutsu and the tactics used by Ninja during feudal Japan.
