Shinjutsu

are techniques of the highest form mainly used by members of the Ōtsutsuki clan. According to Amado, all ninjutsu are attempts to reproduce the effects of shinjutsu.

Trivia

 * Momoshiki claimed to have intimate knowledge of every Shinjutsu still in existence, and disputed Amado's claim that Ada's entrancing ability is a shinjutsu, having never heard of it.
 * Hagoromo Ōtsutsuki's mastery of Ninshū had many similarities to Shinjutsu, including not needing hand seals to perform his techniques.
