Taijutsu (体術, Literally meaning: Body Techniques) is a basic form of techniques and refers to any techniques involving the martial arts or the optimisation of natural human abilities. Taijutsu is executed by directly accessing the user's physical and mental energies, relying on the stamina and strength gained through training. It typically does not require chakra, though chakra may be used to enhance its techniques. Taijutsu generally require no hand seals to perform, occasionally making use of certain stances or poses, and are much quicker to use than ninjutsu or genjutsu. Taijutsu is simply put: hand-to-hand combat.
Although it is used by nearly all ninja, some characters use taijutsu almost exclusively like Rock Lee and his teacher Might Guy, are experts of many taijutsu techniques. Example of taijutsu techniques are Dynamic Entry and Leaf Whirlwind. The Hyūga clan's Gentle Fist, however, makes extensive use of chakra and demands great skill in its control. The taijutsu techniques are the right choices for those that want to save their time and chakra, or for those who rely on their physical attributes. It can also be used uniquely in collaboration with ninjutsu to create nintaijutsu techniques.
