-Taijutsu simply means hand to hand combat. It is a fighting style where the user utilises his raw natural physical abilities relying on gained strength and stamina from training. This doesnt rely on chakra to do but it can be used to further enhance taijutsu moves.
-Because taijutsu doesnt need handseals its relatively quicker to perform than ninjutsu and genjutsu in most cases.
-Guy sensei,Rock lee and Neji are all great taijutsu users, even though Neji's techniques depend mostly on chakra to be complete.
-Some techniques are Leaf Whirlwind, Dynamic entry and Gentle fist.
-Since taijutsu is incredible fast and doesnt depend on seals, i would use it to dispose of foes around me quickly.
