name: Finger Engraving Seal
Rank: C
Description: Shikoku Fuuin is a Fuuinjutsu executed by forming the needed sealing chakra on his finger, the user can engrave a message into an object.

name: Five Seal barrier
Rank: C
Description: This technique creates a barrier around a place by placing four "forbidden" (禁, kin) tags in different locations surrounding the place to be protected, a fifth tag on the location to be protected. The tags are placed on flat surfaces, and are connected with the user's chakra. This technique turns the entire range surrounded by the tags into a barrier space, and inside the space, the material's destruction is "forbidden". Using any kind of physical attack to try and destroy something in the barrier is folly, as it will only lead to injury. To cancel this, it is necessary to search for the four tags and tear them off simultaneously. Meaning there must be at least five people on a team to cancel it.
Even if the tags are removed, there is a final obstacle. The user can add a trap that will create perfect copies of those who have removed the seal, preventing them from returning immediately.

name: Cloth Binding Technique
Rank: B
Description: The user uses a giant roll of cloth to tightly wrap up the intended opponent, completely immobilising them, thus preventing them from moving or using any techniques. The ability itself is versatile as once completed, the addition of further seals can be placed on top of the bound victims, preventing them from even being summoned while in effect. This technique is used by Sunagakure ninja. Mere physical contact with the cloth seems to be required to use this technique.

name: Dark Sealing Method
Rank: B
Description: This seal is used in conjunction with the Four Black Fog Battle Formation. After the Sound Four seal the individual in the container, this seal is added as another layer of protection. To create the seal, the user writes the incantation in blood on the sealing paper and then attaches it to the container before activating it with a hand seal.

name: Four Black Fog battle Formation Technique
Rank: B
Description: A barrier ninjutsu, performed by all of the Sound Four, used during the temporary "death" of those forcing the advancement of their cursed seal to its second level. The technique seals them in a coffin while the process takes place, and does not even allow the Byakugan to see inside. The Dark Sealing Method can be used for an additional layer of protection. The seal seems to be naturally lifted once the cursed seal has advanced to level two.

Name: Sealed Iron Wall
Rank: B
Description: A seal placed on the Fire Temple's gate, in order to defend against intruders from the outside world. The two statues placed on either side of the gate form a barrier. The seal can only be cancelled by pouring in the Gift of the Hermit Group, special chakra peculiar to the ninja monks of the Fire Temple.
However, as shown when Kakuzu used his Earth Release: Earth Spear to strike the gate, a powerful enough physical attack can destroy the seal.

name: Lightning Blade Creation
Rank: B
Description: This is a special "ninja tool summon" that allows the user to seal ninja tools like swords or kunai into a scroll or their clothes beforehand, allowing them to be called upon when needed. The ninja tools can be summoned in an instant just by touching the sealing "marks" which can be drawn anywhere. The greatest advantage of this technique is that the time between taking out a ninja tool, taking the right stance and actually throwing it is greatly reduced. Also when a weapon such as a Fūma Shuriken is summoned, the time needed to throw it can be further shortened by having prepared the weapon in its fully extended form beforehand.
The ninja tools are thrown with the actual speed of a "flash of lightning", ruining the opponent's outset of the battle, and snatching away the initiative. Furthermore, because the summoned ninja tools can remain hidden until right before they are used, if this technique is mastered, there are an exceptional number of possible tactics. A large number of ninja tools can be stored within the sealing marks, which can make the efficiency of this technique last longer.

name: Contract Seal [Keiyaku Fūin]
Rank: A
Description: When the user implements this fūinjutsu on a summoner, it removes any direct control the summoner has over a summoned creature. Close contact appears to be required for the implementation of the seal. Minato Namikaze used this technique to wrest a Sharingan-controlled Kurama from Tobi's control. Though the Contract Seal removes the summoner's ability to control its summon, it does not give the user of the fūinjutsu the ability to control the summon in turn, nor does it remove a summoner's ability to continue to summon the creature.

name: Four Symbols Seal
Rank: A
Description: This is a sealing technique based on the fūinjutsu of Uzushiogakure's Uzumaki clan.The sealing formula is used to seal any target into a human body or an object, and is mainly used when a giant enemy or evil spirit needs to be sealed away. To use it, it is necessary for the user to have great ability.
When two Four Symbols Seals are used together, they form the Eight Trigrams Sealing Style. When Minato sealed the Nine-Tailed Demon Fox into Naruto Uzumaki, he left an opening at the space where the two four symbols seals met, allowing the Nine-Tails' chakra to mix with Naruto's own. Minato also left behind a key with Gerotora, could be used to freely manipulate the seal.

name: Evil Sealing Method
Rank: A
Description: This technique is used to suppress technique-induced marks on a person. Marks of weaker power can be completely suppressed by this technique alone, but for marks of higher power, like Sasuke Uchiha's Cursed Seal of Heaven, it will cause the seal's power to become dependent on the recipient's own willpower to some extent, especially if the sealer is not experienced enough to strengthen the seal with his own power. It is also capable of holding back certain kekkei genkai, such as that of the Kurama clan as seen when Kurenai tried to do this.
This seal requires a high number of hand seals to be performed and consumes large amount of chakra from the user. Preparation for this technique requires two concentric circles with kunai placed in intervals along the circumference, in addition to a number of characters written in blood that radiate out from the centre of the cursed seal.

According to Kakashi, this technique is quick, but painful. The seal can be removed at any time by the caster or whoever the seal is on, as demonstrated during Sasuke's battle with Naruto in the Valley of the End. Since this seal relies on the will of the individual on whom it is placed, the affected may be able to will it away without an unsealing technique.

name: Evil Releasing Method
Rank: A
Description: The Evil Releasing Method is a direct counterpart to the Evil Sealing Method, this technique is used to release technique-induced marks on a person rather than sealing it. Compared to the Evil Sealing Method, the Evil Releasing Method requires far less preparation.

Name: Five Elements Seal
Rank: A
Description: This technique produces a powerful seal that is used to block or disturb the flow of chakra in a target. Once the seal is completed, the target will become unconscious and unable to fight for a short time. Orochimaru performed this technique to tamper with Naruto Uzumaki's seal. The original seal allowed a small amount of the Nine-Tails' chakra to always mix into Naruto's, but the additional seal disturbs this, preventing Naruto from using the Nine-Tails' chakra or even controlling his own chakra properly. This is because an odd-numbered seal creates an imbalance when placed on top of an even-numbered seal.

Name: Five Elements Unseal
Rank: A
Description: This technique can be used to remove fūinjutsu of up to equal power, like its counterpart, the Five Elements Seal

name: Iron Armour Seal
Rank: A
Description: This is the fūinjutsu used by Kumogakure to seal Gyūki into its respective hosts. The seal itself takes the form of the kanji for "iron" (鉄, tetsu) and is usually printed somewhere on the jinchūriki's body: Killer B's right shoulder, and Fukai's chest.

name: Transcription Seal
Rank: A
Desciption: This technique allows the user to seal a jutsu or item within a person. The user can customize how it's activated and to what extent.

Name: Torii Seal
Rank: A
Description: When Naruto first obtained Nine-Tails Chakra Mode, his previous seal's outward appearance had changed into a shape of one of the Sage of the Six Paths' magatama beads, along with a swirl design that resembled Uzushiogakure's symbol.
By using the seal's key, he can create several massive interlocking torii that can even immobilise and imprison Kurama with ease. Naruto then isolated Kurama's chakra in another part of him away from the beast itself in between four torii, so he could access it freely. It was later revealed that Kurama isn't always bound by the torii and has freedom of movement behind its cage, but Naruto can enter the cage without breaking the seal and still manipulate the torii to immobilise the beast if he wants. The seal's outward appearance changes slightly when Naruto forms a hand seal

Name: Tailed Beast Extraction Technique
Rank: S
Description: After setting up an area, the user can extract a tailed beast from its jinchūriki. The jinchūriki is bound by sealing formulas. Obito had to wait for a very long time until Kushina's seal was weak enough to use this technique to extract Kurama

name: Eight Trigrams Sealing Style
Rank: S
Description: The Eight Trigrams Sealing Style, consisting of two Four Symbols Seals, was used by Minato Namikaze to help Naruto Uzumaki access the chakra of Kurama, the tailed beast sealed within him.
To perform the technique, the user must first summon a ceremonial throne and place the target on it. The seal was not automatically visible on Naruto's belly, but became perceptible whenever he drew Kurama's chakra.

Whenever Naruto and Kurama conversed, it occurred within Naruto's subconscious, which was depicted as a basement of a boiler room or a sub-level of a power plant, with pipes running across the ceiling and the floor being flooded over with water. On the entrance gate of Kurama's cage, there was a parchment of paper that said "seal" (封), which covered the lock that kept the fox in. Minato also sealed his and Kushina's remaining chakra into Naruto with this seal. Minato appeared in Naruto's subconscious when Naruto transformed into his eight-tailed form, and restored the seal to its original strength, but he could only do it once.[8] Kushina also appeared and assisted Naruto when he later fought Kurama to control its chakra.

Although the seal itself was seemingly destroyed during Naruto and Kurama's fight, it evolved into a new, stronger seal that consisted of massive torii that was capable of imprisoning the fox with ease after Naruto separated it from its chakra and merged with his own. The new seal's gate has the same lock as its previous one.

Name: Reverse Foul Symbols Sealing Technique
Rank: S
Description: This technique is a fūinjutsu that the user places across their chest, and sets it to activate upon their death. The technique releases four symbols from the user's body that then forms a large, black sphere around them. Anything caught inside the sphere's area is then drawn in and sealed within the user's corpse.

name: Sage Art: Gate of the Great God
Rank: S
Description: After entering Sage Mode, the user manifests a select number of massive torii that fall down from above, in order to pin an intended target between the gate and the ground. The size and strength of these torii is such that they can even be used to immobilise the Ten-Tails

The exact number and size of the torii involved in this technique can vary dependent upon what the user specifies:
Seal Ten (封十, Fūtō; Viz "Ten Seals"): Creates ten torii that can be used to pin several individual targets simultaneously.
Seal Head (封頭, Fūtō; Viz "Head Seal"): Creates a single, large torii, intended to pin the target's neck beneath it, so as to immobilise their head.

Name: Sealing Technique: Phantom Dragons Nine consuming Seals
Rank: S
Description: The Sealing Technique: Phantom Dragons Nine Consuming Seals is a technique that was used by Pain and the other members of Akatsuki to forcibly drain the spirit and chakra of the tailed beasts from their still-living jinchūriki, then to seal it in the Demonic Statue of the Outer Path. The technique took three full days to complete if nine of the Akatsuki members were present. Kisame Hoshigaki suggested that it "may take longer without Orochimaru". When reduced to three people, Zetsu claimed that, with so few people left to perform the technique, it would take a while.
To prepare for the technique, Pain would summon the Demonic Statue, after which each member would then stand on one of its fingertips, corresponding to their specific ring finger. When performed, this technique caused the bit to fall out of the mouth of the statue. Each of the Akatsuki members would then concentrate, causing the kanji of their rings to appear on the nail of the finger they were standing on. Nine dragon-like effigies then poured from the statue's mouth, surrounded the captured host, and painfully removed the tailed beast from them. In the case of an unsealed tailed beast, the same thing happened to the beast itself, and still took as much time as if it were sealed. After the process was complete, the beast was sealed within the statue, and one of the statue's nine eyes opened. The host then died due to the removal of their tailed beast. There is a numerical order with the Nine-Tails needed be sealed last, or the statue would shatter.
