The Summoning: Impure World Reincarnation binds the soul of a deceased person to a living vessel, restoring them as they were when they were alive in order to do their summoner's bidding. It was originally created by Tobirama Senju, after which he declared it a kinjutsu. Orochimaru rediscovers the technique decades later, and Kabuto Yakushi subsequently perfects it.
Before this technique can be performed, the user must first acquire some of the DNA of the person they intend to reincarnate. Kabuto remarks that this basically amounts to grave-robbing, although blood stains or organs salvaged after the target's death also work. The soul of the intended reincarnated must also reside in the Pure Land; souls trapped in the stomach of the Shinigami, for example, cannot be reincarnated so long as they reside there. A living sacrifice is also required for the reincarnated soul to use as a vessel.
To actually perform the Impure World Reincarnation, the DNA of the person to be reincarnated is smeared on a special scroll. Once the scroll is activated, the remains spread out in the form of a special seal with the living sacrifice in the centre. Then dust and ash encase the sacrifice's body, giving them the same appearance that the reincarnated had at the time of their death; the process is apparently painful for the sacrifice. The sacrifice's chakra signature is completely overridden with the chakra of the one being reincarnated. Although the sacrifice is still technically alive so long as the technique is active, their body will never again be theirs and the body will die when the reincarnated soul is released.
Although Tobirama was the technique's creator, his usage had two flaws: the reincarnated souls were not as powerful as they were while alive and he could only control so many at a time. Orochimaru is stated to have mitigated both flaws somewhat, but it is Kabuto who entirely eliminates them, perfecting the Impure World Reincarnation to such a degree that the reincarnations are practically as they were during life and he can control as many at a time as he wishes to, resources permitting. His improvements, combined with the fact that performing the Impure World Reincarnation requires no chakra from the user, causes Kabuto to declare it the most powerful jutsu in history.
Reincarnations can be mobilised like standard infantry, where they must travel to their destination. Alternatively, coffins that contain them can be summoned to a location, assuming someone is there to perform the summoning; the anime does not consistently require this. Reincarnations can be recalled in a similar way, with a coffin emerging around them to take them back.
The only discretion a user needs to exercise for the Impure World Reincarnation is how much control to exert over the reincarnated soul. After first performing it the user is only able to restrict their movements. In general, this limited control is not an issue for the summoner, and they will typically "deactivate" the reincarnation, placing them in a coffin for storage and transportation until they're needed. However, when the perfected Impure World Reincarnation is used to revive somebody, there comes a possibility that they will be strong enough to resist this control; Orochimaru notes Hashirama Senju could break free if he chose to.
In order to actually be able to control their actions, the user must implant a special talisman - generally attached to the end of a kunai - within the reincarnation's brain. The talisman's design determines how strong the control is:
- At its most basic, the reincarnated soul retains their personality, giving them the freedom to approach a given task however they like so long as it broadly carries out the summoner's bidding. On the one hand, this makes them more useful in combat because they know how best to use their own abilities and, if deployed against somebody they knew when they were alive, there is a possibility for psychological warfare. On the other hand, although they are compelled to do as their summoner wishes and act without reluctance, they can undermine their summoner to a degree, either by making poor decisions that opponents can take advantage of or by giving opponents advice about how to defeat them. Despite its risks, Kabuto prefers this level of control.
- At its strongest level, the reincarnated soul's personality is entirely eliminated. The summoner instead controls all of their actions, even permitting them to speak through the reincarnation or summon other reincarnated souls to their location. Although this guarantees the reincarnated soul will only ever act as desired, they are less resourceful and it requires the summoner's attention for every action that must be taken, making it difficult for them to multi-task depending on the circumstances. Orochimaru prefers this level of control. Kabuto has at times rewritten talismans remotely in order switch to this level of control when the situation calls for it.
Kabuto and Orochimaru are able to strengthen the bindings they use through external means: Kabuto siphons chakra from the cursed seal Anko Mitarashi is branded with; Orochimaru uses Senju cells. Relatedly, any level of control creates a traceable chakra signature between the reincarnated soul and their summoner, allowing reincarnated sensors to trace the summoner's location.
When first summoned, the body will appear grey and in a state of minor decay: marred by cracks and other imperfections. If the summoner chooses to, they can rejuvenate the reincarnation while planting their control talisman, restoring their complexion and reducing some of the imperfections; this is merely aesthetic and the signs of decay do not inhibit their abilities. An unavoidable characteristic of a reincarnated body is the darkened sclerae, with a soul that retains its personality having grey sclerae and a soul with a suppressed personality having black sclerae.
A reincarnated individual will have all the abilities they had during their life, including kekkei genkai and kekkei tōta. They are psychically restored as they were at the time of their death, including any physical handicaps they may have possessed, such as Nagato's damaged legs. Exceptions exist: illnesses they had will not be preserved, nor will any physical damage that contributed to their death. There is some inconsistency of whether or not foreign body matter will be restored as well: Hanzō retains the poison gland of the black salamander, but Madara Uchiha does not have access to Hashirama Senju's genetic material and thus Kabuto must artificially reproduce it for him.
Clothing is reproduced according to what they wore when they died, although it is merely a superficial aspect of their reincarnated body; armour offers no actual protection, being of the same ashen material as the rest of their body. Reincarnated members of Akatsuki are, however, outfitted with different cloaks than they used to wear. Weaponry is usually not retained and must instead be gathered by the summoner; the reincarnated Seven Ninja Swordsmen of the Mist only have access to those swords Kabuto is able to acquire. One exception seems to be the Gold and Silver Brothers' Treasured Tools of the Sage of the Six Paths, which are still seemingly stored within the brothers' bodies.
Despite being largely the same as they were while alive, the reincarnated can never be as powerful, even with the perfected Impure World Reincarnation; Madara's reincarnated body is successfully bound by the Sage Art: Gate of the Great God, which he easily breaks free of as soon as he is restored to life. Likewise, there are some things a reincarnated body simply cannot do, such as access all the abilities of the Rinnegan or become the jinchūriki of the Ten-Tails.
One of the major benefits of the Impure World Reincarnation is that it grants immortal bodies to those who are reincarnated. Any damage they receive will regenerate in time and, assuming the damage is not too debilitating, they can continue attacking even before their body recovers. This was one of the main purposes Tobirama created the technique for, as he would use one or more reincarnated souls to perform a series of Kamikaze-like attacks until the opposition was wiped out; he created the Mutually Multiplying Explosive Tags specifically for this purpose. Reincarnated bodies do not bleed, except in those cases where blood is needed to perform the Summoning Technique.
A second benefit is the limitless chakra reserve that the reincarnated individuals have access to; they can fight eternally and perform ordinarily physically demanding or chakra-intensive jutsu without issue. (However, the Hokage reincarnated by Orochimaru report at different times that they have run out of chakra.) They are still subject to certain inherent demands of the jutsu itself, such as the Second Tsuchikage's chakra supply being cut in half after using the Fission Technique or only being able to create a certain number of clones. Other side-effects may still manifest, as when Itachi Uchiha's eyes bleed from using his Mangekyō Sharingan, but he is not inhibited by it.
The reincarnated body can be further enhanced. Madara Uchiha's body is restored to its physical prime rather than the withered state it had when he died, he receives a graft of Hashirama Senju's so he can use Wood Release, and he has access to dōjutsu he gave up during his life. The reincarnated jinchūriki similarly have their respective tailed beasts sealed back into them.
- Remove the soul from the reincarnated body, such as with the Dead Demon Consuming Seal.
- Have the summoner end the technique. As they are unlikely to do this voluntarily, using a genjutsu to trick them into cancelling the technique is ideal. The sequence of hand seals for cancelling the technique is Rat → Ox → Monkey → Tiger → Dragon → Boar and saying "release" (解, kai). (When demonstrating the technique to Tobi, Kabuto lied that the seals to release it are Dog → Horse → Tiger.) The Sage of the Six Paths has demonstrated the ability to release the Impure World Reincarnation despite not being the summoner.
- A less reliable, though equally effective method is to have the reincarnated soul be affected in some emotional way that gives them closure, allowing their soul to break free of the Impure World Reincarnation's influence.
When a soul is released from the Impure World Reincarnation, their body disintegrates back into dust and the sacrifice's corpse will be left lying in the debris. The soul may linger briefly - with their personality restored if it was being suppressed - to leave parting words or take final actions. Souls released by their summoner will be enveloped in light throughout the process.
Even if the Impure World Reincarnation cannot be broken conventionally, reincarnated bodies can still be neutralised. During the Fourth Shinobi World War, the Allied Shinobi Forces develop the method of binding the reincarnations' bodies so that they can't move and then placing a seal on the bindings so that they no longer pose a threat. Yin–Yang Release, as manifested in Truth-Seeking Balls, can negate the regenerative properties of reincarnated bodies, reducing their effectiveness and, if used to strike a vital spot, kill them for all intents and purposes.
There are also ways for a reincarnated body to escape their summoner's influence. Itachi Uchiha is targeted with Kotoamatsukami, displacing Kabuto's commands with different orders. Kabuto can regain control of Itachi by gaining access to the control talisman, and in fact is still able to release him from the Impure World Reincarnation. Conversely, if the reincarnated soul knows the hand seals, they can sever the summoner's contract with them; in the anime, the seals are Snake → Ram → Boar → Dog → Tiger. This grants them full control of their own actions, all the benefits of an immortal body, and prevents the summoner from releasing them from the Impure World Reincarnation. Madara Uchiha describes this as "the one risk of the technique".

- During the Konoha Crush, Orochimaru attempted to reincarnate Minato Namikaze, unaware that his soul did not reside in the Pure Land. For that reason the summon failed. The failed coffin is not seen in the manga, but in the anime it briefly appears with "four" (四, Yon) written on it. However, because of the mechanics of this technique, it's illogical that Orochimaru tried to summon the Fourth. He should've noticed that that's impossible when he had to do the first summoning (the one with the ritual).
- In the anime, Orochimaru's reincarnation of Osoi was an accident, as he intended to reincarnate Toroi.
- Kabuto mentions his desire to reincarnate certain shinobi:
- Jiraiya, though his body lies at the bottom of the ocean where the water pressure is too great to reach. However, he claimed that the bloodstains on the Six Paths of Pain's weapons may provide enough DNA. Tobi denies him this request on the basis that doing so would be "pushing [his] luck".
- Shisui Uchiha, but Kabuto could not find his body. He suggested that one of Shisui's eyes that was crushed by Danzō Shimura, whose corpse was in Tobi's possession, would be sufficient. As with Jiraiya's case, Tobi threatened him not to push his luck.
- In the anime, Kabuto's reincarnation of Chūkaku and Heiji are accidents, as he intended to reincarnate Chiriku and Hanzō, respectively.
- Kabuto is seen using a grid to keep track of all the reincarnated individuals he controls, with a pebble representing each shinobi. It is not clear if there is some actual connection between the grid and those he reincarnates or if it's a mere convenience for him. In the anime, the pebbles crumble when the reincarnation is sealed. All of the pebbles are light-coloured except for Madara Uchiha's, whose is black. In the anime, the failed reincarnations are represented by piles of sand.
- "Edo" (穢土, Literally meaning: Dirty Soil) is what Japanese Buddhists call the normal world, unenlightened people live in. The current, living world. The world of the people who have not yet have escaped the polluting thoughts (greed, hatred, delusion, etc.) that result in suffering.
- A possible translation of Tensei is "Resurrection". In terms of this technique, both "Reincarnation" and "Resurrection" can be found; the sacrificed body is reincarnated into the body of the summoned shinobi, while the reincarnated shinobi is resurrected from the dead.
- In Naruto: Ultimate Ninja 2, Orochimaru reincarnates the Third Hokage despite his soul not being in the Pure Land.
- During the original Naruto anime, a reincarnated target's eyes appear normal, albeit glazed over. In Naruto: Shippūden, the eyes are corrected to match the manga.
- In Ultimate Ninja Storm Generations, Kabuto Yakushi (Snake Cloak Form) uses the Impure World Reincarnation as his ultimate technique. He summons Kakuzu, Itachi, and Deidara, who attack the opponent using the Lightning Release: False Darkness, Fire Release: Great Fireball Technique, and C1, respectively.
- In the anime, when eradicating the personality of Hanzō, Kabuto used several hand seals instead of just one.
