Taijutsu(体術, literally "body technique" or "body skill") is a Japanese blanket term for any combat skill, technique or system of martial art using body movements that are described as an empty-hand combat skill or system. The term is commonly used when referring to a traditional Japanese martial art but has also been used in the naming of modern martial arts such as Bujinkan Budo Taijutsu. Taijutsu is similar to Karate but is more focused on the body techniques. More specific names than taijutsu are typically used when describing a martial art, such as jujutsu (focusing on throwing, grappling, and submission), judo (focusing on throwing and grappling), aikido (focusing on throwing and joint locks) as well as karate and kenpō (focusing on striking).
The Japanese manga Naruto mentions Taijutsu as one of the three basic ninja methods, the others being Ninjutsu and Genjutsu. This also refers to almost any hand-to-hand combat the ninja use. Some ninja become so proficient with both ninjutsu and taijutsu that they combine them into Nintaijutsu. This can be infusing their fists with chakra to enhance their strength, enveloping their hand in lightning or wind chakra to use as a make-shift sword, or even, in Sasuke and Obito's cases, the ability to use an opponent's hand to weave hand signs if they are in close combat, so as to unleash a powerful jutsu (Fire Release: Great Fireball Technique in both their cases), point-blank.
