Although downplayed for much of the series, Orochimaru is also very skilled in the use of fūinjutsu, even in the midst of battle. Most notably, he has been seen using the Five Elements Seal, to seal off another's access to chakra and thus, rendering them useless. Using this technique, Orochimaru was not only land a seal on an enraged Naruto, but also completely subdue the Nine-Tails' chakra. In the anime, he was shown capable of using its counterpart, the Five Elements Unseal. His prowess with it, was great enough to release the seal and extract a tailed beastfrom its jinchūriki. 

 

 Summoning: Impure World Reincarnation

  Orochimaru is one of the three people capable of performing Summoning: Impure World Reincarnation, further perfecting the technique developed by the Second Hokage, Tobirama Senju. In his first shown use, he reincarnated both the technique's creator and Hashirama Senju to fight against his teacher, Hiruzen Sarutobi. Though Hiruzen sealed the part of his soul that represented his arms to bare him from using Impure World Reincarnation, Orochimaru used the Shinigami Maskduring the Fourth Shinobi World War to spiritually restore himself and summoned all four Hokage at once.
