Sage Mode (Grandfire)


 * This article pertains specifically to the Sage Mode used by Jiro Uchiha. For the generic technique, see Sage Mode.

Sage Mode is the result of using natural energy along with a ninja's normal chakra in perfect balance to drastically empower a ninja's abilities.

Overview
Senjutsu (仙術; Literally meaning "Sage Techniques") refers to a specialized field of techniques that allows the user to sense and then gather the natural energy (自然エネルギー, shizen enerugī) around a person. Senjutsu practitioners can then 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), adding a new dimension of power to the sage's chakra, resulting in the creation of "senjutsu chakra" (仙術チャクラ, senjutsu chakura). This chakra cannot be seen by anyone other than those who have been trained in senjutsu.

This new chakra enables the user to enter an empowered state called Sage Mode, which can then drastically increase the strength of all ninjutsu, genjutsu, and taijutsu. A person who is able to use senjutsu is called a sage (仙人, sennin). It would seem that there are only three ways to learn senjutsu. One of them is to study under toads from Mount Myōboku, as Shima, Fukasaku, Jiraiya and Naruto have done. Gamakichi and Gamabunta also seem to be familiar with it. Another way is to study under snakes from the where Kabuto Yakushi learnt it. The is the third place to have knowledge on senjutsu. A prerequisite to being able to use senjutsu is that the user must have a great reservoir of chakra themselves in order to manipulate the natural energy.
