Genjutsu (幻術; Literally meaning "Illusionary Techniques") are techniques that are employed in the same fashion as ninjutsu, requiring chakra and hand seals. However, the primary difference between the two is that the effects of genjutsu are illusory; instead of attacking the victim's body, like taijutsu or ninjutsu, genjutsu techniques manipulate the flow of chakra in the victim's brain, thus causing a disruption in their senses. According to the Second Mizukage, genjutsu fittingly falls under the broad category of Yin Release.[1]

This is frequently used to create false images or to cause pain from trauma (because the body is led to believe it is in pain); however, there are plenty of other uses depending on the situation. They are not used as often as ninjutsu because they don't physically harm the opponent, but several characters have made themselves well-known for their great prowess with genjutsu like Itachi Uchiha, Kurenai Yūhi, the Second Mizukage, and Tayuya. Genjutsu can also be used to manipulate others, similar to brainwashing by feeding the victim illusive suggestions, the primary example being Tobi controlling Yagura. However, there exists at least one genjutsu, Izanagi, that has the opposite effects to normal genjutsu, by changing reality to illusion and vice versa. Genjutsu can also be used for other supplementary purposes such as interrogating an individual by breaking their will.

Genjutsu is created when a ninja controls the chakra flow of the opponent's cerebral nervous system, thereby affecting their five senses. Those with special abilities like the Uchiha clan's Sharingan — which can cast generic genjutsu — or with high intelligence have an easier time executing and countering genjutsu. Those under the influence of genjutsu will either appear to be unconscious or continue to move around under the pretence of the genjutsu. The latter is very effective in battle as a genjutsu user can make themselves appear to be somewhere else and attack the victim from behind or change the environment to make the victim see a flat plain where there is a steep cliff.

Genjutsu attacks usually require a lot of skill, and, if performed incorrectly, will not work; even Jiraiya had trouble performing such techniques.[2] Genjutsu is most often used by ninja with very precise chakra control and very high intelligence, two notable users being Itachi Uchiha and Kurenai Yūhi.[3]

It is explained in the anime that because genjutsu affects activity throughout the prosencephalon structure of the brain, humans, dogs and other species of mammal are therefore all affected by genjutsu; however, the kikaichū, like all insects, lack such a structure to their brains, and so do not even notice it: as Shino Aburame put it, insects are ruled almost solely by their senses alone, which makes them immune to genjutsu and gives the Aburame clan an ability to detect it, even when heightened senses become succeptible.[4]

Shikamaru Nara states that among genjutsu the most dangerous are those that affect the opponent with sound allowing the user to stay out of sight. Tayuya is a great example of this sound-based, long-range type of combat.[5]

In the anime, it is shown that genjustu can be "stored" inside of special pills that produce the genjutsu once the target ate a pill and went to sleep.[6]

The sometimes more complex genjutsu, although still employing illusions, have elemental chakra natures associated with them. Techniques such as these are less common, however. Such examples are Water Release Genjutsu: Demonic Phantom Fog Prison and Lightning Illusion Flash of Lightning Pillar.

Combating Genjutsu

To combat the effects of genjutsu, there are several options:

  • The ninja needs to stop the flow of chakra in their body, and then apply an even stronger power to disrupt the flow of the caster's chakra; this is called Genjutsu Dissipation (幻術解, Genjutsu Kai). This can also be done by an unaffected ninja by applying a sudden surge of chakra into the affected person.[7] In addition, tailed beasts can break their jinchūriki out of genjutsu in a similar fashion if they have a good enough cooperation, as seen in Killer B's case.[8][9]
  • Another is through intense pain not caused by the genjutsu and utilising the resulting pain to bring their senses back in order (of the first two options, the latter seems more effective in most situations, or at least is the easiest).[10]
  • Another option is accessible only to Sharingan wielders. Members of the Uchiha clan can break or see through genjutsu using their Sharingan. Breaking Tsukuyomi is possible with an ordinary Sharingan, but requires a lot of skill.[11]
  • Sharingan wielders can also use their dōjutsu to liberate each other from genjutsu. Through eye contact, they are able to literally insert themselves into each other's genjutsu freely allowing them to break whatever genjutsu it is that imprisons their comrade.[12]
  • The Byakugan is also noted to be able to tell when genjutsu is being used.[13][14]
  • Ordinary people can sometimes train their eyes (without Sharingan) to break genjutsu through unknown means, like Deidara.[15]
  • One can prevent a person from casting genjutsu using obstructive techniques like the Hiding in Mist Technique to prevent one from being trapped by an ocular genjutsu as Zabuza demonstrated against Kakashi.[16]
  • In the anime, it was shown that strong smells like that from the Chilli Pepper Bombs, can counteract genjutsu.[17]

In spite of these methods, some forms of genjutsu like Itachi's Tsukuyomi and Shima and Fukasaku's Demonic Illusion: Toad Confrontation Chant may not be broken easily, either due to their near-instant effect like the former, or their ability to render one unconscious and paralysed altogether like the latter. In addition, one must realise that he or she is under the effects of genjutsu before attempting to break out of it. This can be done by observing the changes in one's own chakra like Karin's chakra-sensing ability.[18]
