As I understand Genjutsu is, affecting the opponent's chakra network with your own chakra through some medium, and create illusions in their mind. It's basically 'Yin Release' through some medium. Incase of Sharingan users, it's done through eyesight. They can cast Genjutsu when the opponent see the caster's Sharingan. That way they imply their chakra into the opponent's body.

Incase of Sage Toads and Tayuya, It's through sound. So, whoever is within the range could be affected by the Genjutsu.

The question is, Is there any other way to cast Genjutsu ? How come Kurunei is able to cast Genjutsu? Is it through eyes?

  • Actually it can be thru anything. Itachi cast it using his finger too, other than his eyes. For more information, ask your grandson's reincarnation, @UchihaMadara. Lol. Commented Nov 10, 2014 at 7:38
  • @SakuraiTomoki It's obvious that you can imply chakra through physical touch. But could you tell me in which episode/chapter Itachi does that? Commented Nov 10, 2014 at 8:32
  • No, no touching. Just moving his fingers and Naruto saw that, then he falls to his genjutsu. It was when Naruto, Kakashi, Sakura, adn Chiyo-baa-sama fought fake Itachi. Commented Nov 10, 2014 at 9:51
  • Sorry, I read it wrong :) Commented Nov 10, 2014 at 10:43
  • @SakuraiTomoki Actually Itachi was having a spare Sharingan in a ring in his finger. Naruto fell into genjutsu only after seeing that... So still that jutsu is cast through eye contact... Commented Nov 10, 2014 at 13:20

Genjutsu was defined by Jiraiya as "an advanced form of Ninjutsu". It affects the chakra currents in the opponent's brain.

Chakra disturbances can be caused through any of the senses, sight, hearing, smell, taste or touch. Additionally, apparently, Yin type Genjutsu (genjutsu that involves creating things from nothing, like Kurenai's) can be cast on an opponent without apparent connection to the senses.

The Second Mizukage's Yin genjutsu used chakra infused steam to mess with the opponent's sense of distance, over a wide area (so lots of opponents affected at the same time).

  • I took this line from wikia. "According to the Second Mizukage, genjutsu fittingly falls under the broad category of Yin Release". Doesn't it mean that all Genjutsu's are some kind of Yin release ? What do you specifically mean by 'Yin Type Genjutsu' ? Commented Nov 10, 2014 at 8:52
  • The fourth databook explained that not all genjutsu is Yin, and not all Yin is genjutsu. Genjutsu that involved creating form from nothing are Yin genjutsu. At least, that's what I understood. The official translation for the fourth databook is not out yet. Commented Nov 10, 2014 at 8:54
  • All Yin is not Genjutsu, I agree on this. So far, we have seen sight(Sharingan),hearing(Tayuya,Toads),taste(Genjutsu pills). How do you say about Smell and Touch ? Any examples? Also, Do you agree with SakuraiTomoki's comment on Itachi casting Genjutsu by finger touch? Commented Nov 10, 2014 at 9:18
  • Itachi once casted a genjutsu on Naruto just by pointing at him. Commented Nov 10, 2014 at 9:20
  • What kind was that? Do you think it was Yin release? Commented Nov 10, 2014 at 9:43
