Kakashi tells Jiraiya that Rasengan is a dangerous technique after he stopped Naruto and Sasuke who fought for the first time. If it is that dangerous, then why was Naruto allowed to teach Rasengan to Konohamaru?

  • Rasengan isn't a Kinjutsu, Rasengan is just a powerful A-Rank Jutsu. Kakashi mentioned that Rasengan is dangerous because if Naruto's Rasengan clashed with Sasuke's Chidori ( in their battle in the hospital only ) Sasuke would Die. Rasengan is an Technique developed by the Fourth Hokage in 3 Years, while Chidori is a technique developed by Kakashi when he was 6 years old only. Jul 10, 2017 at 21:37
  • Since it's not a forbidden jutsu, I do not see a reason why he shouldn't be teaching it to Konohamaru. How else do you expect the jutsu to be passed over to the next generations? It's a powerful technique and deserves to be passed along, just like the Sexy-justu :D

Although Rasengan may be a very dangerous technique, it's not a forbidden technique, so anybody can teach it to everybody.

The Naruto wiki has the categories for forbidden Jutsus:

  • Techniques that cause harm to the user themselves, such as opening the Eight Gates, which the mere use of is both highly useful as well as detrimental to the user.

  • Techniques that violate the laws of nature (e.g. the Summoning: Impure World Reincarnation, which reincarnates the dead with a human sacrifice).

  • Certain techniques that are known to cause massive collateral damage, such as the total destruction of a village and end with the death of everyone in it, thus the great moral ramifications of its potential lead many to labelling it as a forbidden technique.

Rasengan does not fit in any of these categories, so it's most likely not a forbidden Jutsu ;).

  • But Naruto is not a chunnin or Jounnin to teach a Genin. Is a genin allowed to teach jutsus?

    @PraveenSharath Everyone is allowed to teach someone, why should it be forbidden^^. And even though Naruto is still a Genin, he is possibly one of the most experienced ninjas in konoha.

    I don't think experienced is the right word (as he is still quite young) the strongest would be more accurate imo.

  • As an important side-note. If anyone should be allowed to teach anyone Rasengan it is Naruto. It is his father's jutsu afterall.
