Senjutsu

refers to the uses chakra created from spiritual and physical energy within the shinobi as well as energy from nature. This results in the drastically increase of physical attacks and jutsu. It would seem that it stems from the toads, as only Jiraiya and Pa have been shown using them, and Gamakichi being the only one who is familiar with it. Other than Jiraiya, Naruto Uzumaki, who also possesses a large chakra reserve that enables the production of high amounts of chakra is the only other human capable of learning and using Senjutsu. Unfortunately, if the user puts too little chakra into using hermit techniques, the technique will not initiate and if the user puts too much chakra into the techniques, the user will start to turn into a frog. If a special scepter is not in tact during the transformation by a toad, the user will completely transform into a frog. Jiraiya, a legendary Sanin, still has trouble using his sage form and he slightly turns into a frog however, Naruto still has not been able to use it.
