Nintaijutsu

is a term used to describe the fighting style used by the Fourth Raikage. A combination of ninjutsu and taijutsu, the Raikage uses nintaijutsu by first surrounding himself with his Lightning Release Armour. This augments the strength of his physical attacks, making them more deadly. His speed and reflexes are also increased. The tailed beast cloak could also be considered nintaijutsu, as it surrounds the users body in chakra. It is unknown if there are other examples of nintaijutsu.
