Jinchūriki (人柱力, literally meaning: Power of Human Sacrifice) are humans that have tailed beasts sealed within them. They exhibit extraordinary powers due to the immense chakra reserves they possess.
Sealing[]
Jinchūriki typically have their tailed beasts sealed into them early in their lives - often shortly after birth - so that they can grow up acclimating to their beast. Which seal is used differs from village to village, with Konoha using the Eight Trigrams Sealing Style and Kumo using the Iron Armour Seal. In order for a jinchūriki to be successful in the long term, it is important for the jinchūriki to have special compatibility or simply unique chakra that can improve their chances. If a jinchūriki has been one for a long time, their chakra will naturally adapt to their tailed beast for better compatibility. In the case of the Ten-Tails, it is also necessary that its jinchūriki have a living body. Even with a powerful enough seal, not just anyone can become a jinchūriki, as a certain level of natural compatibility is still required. Likewise, the greater this compatibility is, the smoother and more potent the jinchūriki can make use of the tailed beast's powers and abilities.
There are several ways in which a tailed beast can be removed from its jinchūriki. If the jinchūriki loses control of the beast or if the seal is simply allowed to weaken enough, the beast will be released. For female jinchūriki, seals are at their weakest during childbirth, due to the nurturing of the child in the womb taking precedence over the reinforcement of the seal. As such, another ninja is required to keep the seal intact during childbirth and restore it to full power afterwards. Akatsuki uses the Sealing Technique: Phantom Dragons Nine Consuming Seals to extract the tailed beasts and seal them within the Demonic Statue of the Outer Path for future use.
Typically, the removal of a tailed beast will cause immediate death for a jinchūriki. Two jinchūriki from the Uzumaki clan, however, have been shown to survive the removal of their tailed beast, but they are left severely weakened and/or left in a critical state. If a jinchūriki is able to hold on to or receive some of their beast's chakra, that will also enable them to survive. The Ten-Tails' jinchūriki can survive its removal so long as the Demonic Statue remains within them, though they will be completely paralysed for a time. Reincarnated jinchūriki can "survive" their beast's removal since they are already dead, but they may lose consciousness depending on the process.
Abilities[]
A jinchūriki has access to their tailed beast's massive chakra reserves. Most jinchūriki learn how to access this chakra on their own and take it by force, but they can also form a symbiosis with their tailed beast and take only what chakra is offered to them. A tailed beast may even give chakra to its jinchūriki without them knowing it, either to try and exert control over the jinchūriki, or simply to protect the jinchūriki and, by extension, itself. If a jinchūriki shares a good relationship with their tailed beast, they can have the beast in question to help them cancel a genjutsu for them.
In addition to the chakra reserves, jinchūriki gain abilities unique to the respective beast. If they are able to survive their beast's removal, they will still have access . At the same time, only while possessing the tailed beast will the jinchūriki have access to forming chakra cloaks, powerful healing of themselves or others. and even transforming of various degrees into said tailed beast. As the jinchūriki transform themselves into the likeness of their tailed beasts, it further increases the power of their abilities. Jinchūriki that have tamed their tailed beast can summon it outside of their bodies while retaining enough of their tailed beast's chakra to avoid suffering the effects of death or critical condition that comes with a tailed beast extraction to fight on their behalf. Afterwards, the tailed beast has to either be resealed or is de-summoned back into the jinchūriki.
