Kyōka-tai (強化体, Literally meaning: Reinforcement Body, Meaning (Viz): Ultimate Body) is a technique that uses complete chakra control and concentration to use the chakra provided from the Rōtasumāku and channeling it through one’s physiology to augment all forms of physical attack to monstrous levels; however, it greatly taxes the user after prolonged use unless they undergo intensive physical training to overcome this weakness.

Toshirō used Kyōta-tai to give him the physical strength to lift and throw the Nine-Tails out of Konoha after using

Shindō used it successfully against Neji Hyūga, but failed against Itachi Uchiha and the Sound Four.


  • Unlike Koutetsu, Kyōka-tai refers to chakra inside the body, meaning it is not present or visible outside of it when used the same way to Tsunade’s Chakra Enhanced Strength and other similar techniques. It functions much the same way as Koutetsu in every other manner.
