Shinjutsu

are chakra-based techniques of the highest order of power, mainly used by members of the Ōtsutsuki clan.

These jutsu, which are unlike ninjutsu or senjutsu, require no hand seals to be performed and enable users to bring upon phenomena resembling. As noted by Amado, ninjutsu are but pale attempts at reproducing the effects of shinjutsu.

Trivia

 * Omnipotence is said to be the most powerful shinjutsu there is.
 * Momoshiki has claimed to hold intimate knowledge of all extant shinjutsu.
 * It is possible that the kekkei mōra techniques wielded by Kaguya Ōtsutsuki derive from (or fall under) shinjutsu, as some such techniques bear similarities to shinjutsu in their functioning, including their lack of requiring hand seals.
