Senjutsu

refers to a specialised field of techniques that allows the user to sense and then gather the around a person.

== Overview ==

Senjutsu practitioners learn to draw the energy of nature inside of them, blending it with their own chakra (created from spiritual and physical energy within the shinobi). This adds a new dimension of power to the practitioner's chakra, resulting in the creation of. In humans, this new chakra enables the user to enter an empowered state called Sage Mode. Those that can absorb or manipulate senjutsu chakra are known as. Currently, there are two known ways to learn senjutsu: One being to learn from the toads of Mount Myōboku as Jiraiya, Minato and Naruto have done, and the other from the snakes from the Ryūchi Cave where Orochimaru and Kabuto Yakushi learned it.

Generally, senjutsu chakra cannot be used by those untrained in senjutsu, though this is not always the case. Members of Jūgo's clan passively absorb natural energy, mutating their bodies. Because they cannot control the chakra they are creating, they tend to go into berserk rages. Orochimaru would experiment on the enzyme responsible for these rages, and use that as the basis of his cursed seals, which would absorb the wielder's chakra and in return feed them Orochimaru's senjutsu chakra.

During the Fourth Shinobi World War, the Ten-Tails' jinchūriki Obito Uchiha gained the ability to nullify normal ninjutsu, but discovered he could not nullify techniques augmented by senjutsu.

After Naruto recieved the "Six Paths Sage Chakra", his Sage Mode became greatly empowered and, along with the chakra of the nine tailed beasts, gained access to a form referred to as Six Paths Sage Mode.

Trivia

 * In the anime, the sound of natural energy being gathered to form senjutsu chakra is the same as the one used for the healing green chakra of the Mystical Palm Technique.
 * The word uses the same hiragana: せんじゅつ, as the Japanese art of, possibly an allusion towards the abilities of Sages to sense persons while in Sage Mode.
 * In the non-canon ninth Naruto OVA, use of senjutsu during the Chūnin Exams was against the rules due to it being an unfair advantage. To use it all will result in an automatic disqualification.
