Isobu (磯撫, Isobu), more commonly known as the Three-Tails (三尾, Sanbi), is one of the nine tailed beasts. It was last sealed within Yagura of Kirigakure.


Young Biju

The young tailed beasts with the Sage of the Six Paths.

Isobu first came into being in the waning days of the Sage of the Six Paths, who used his Creation of All Things ability to separate the Ten-Tails' chakra from its body and divide it into nine separate constructs that would come to be known as tailed beasts in order to ensure that it would never resurface after his death.[3][4] Some time after being created, the Sage sat down with all the young tailed beasts and told them that they would always be together, even when separated, and that one day they would become one entity again with different names and forms than they did. Then, when the time came, they would know what true power is.[5]

Rin and Isobu

At some point in the past, Isobu, who was in the possession of Kirigakure, was sealed within the body of a kidnapped Rin Nohara of Konohagakure. They plotted for Rin to be taken back to her village as a Trojan horse, releasing the tailed beast to wreak havoc in Konoha. This failed, however, as Rin was fully aware of their schemes and opted to kill herself at hands of her friend and fellow team-mate, Kakashi Hatake before their objectives could come to fruition.[6] Eventually, Isobu was revived and sealed within its next jinchūriki — Yagura, the Fourth Mizukage, who managed to gain complete control and harmony with it.[7] However, when Akatsuki went after it, the beast was in the wild; the story behind how it came to be like this is still unknown.

In the anime, Tsunade states that Isobu disappeared after the Third Shinobi World War.[8]


Isobu speaks in a timid manner, referring to itself as "boku" (ボク) which is usually used by young boys.


Young Isobu

A young Isobu.

Isobu primarily resembles a large turtle, but with a crab-like shell, spikes all over its body, and three shrimp-like tails. Under its shell, it has red, muscle-like tissue. It has a pair of human-like arms and hands, but no hind-legs. Its lower jaw is rather big and has teeth-like horns, together with its big forehead, which also has horns, it somewhat resembles a mouth with big teeth, making it look like the rest of the face is inside the mouth. Its eyes are red and have crimson pupils. In the anime, the eyes are red with yellow pupils. Its right eye is constantly closed, indicating some sort of injury, and because of this, it is particularly vulnerable to attacks directed at its right eye. During the last remaining days of the Sage of the Six Paths, Isobu was much was essentially the same in appearance, albeit smaller in size with shorter spikes around its body, but was still many times larger than the Sage.[5]

Isobu's destructive capability.

As a tailed beast, Isobu possesses an enormous amount of chakra and can perform the Tailed Beast Ball. It also has the ability to create coral and swim at very high speeds. In the anime, it could produce a hallucinogenic mist that exploited the victim's insecurities and forced the victim to face them. Tobi suggested that Kisame would have been a better choice for capturing Isobu, given its affinity for water.[9]

Physical Prowess

Shell Spear1

Isobu rolled into a ball.

Isobu can roll into a ball to move about quickly and attack its opponents, making full use of the protrusions on its shell in a manner similar to the Akimichi clan's Spiked Human Bullet Tank.[10] Isobu's tough skin and shell also grant it additional defence, allowing it to withstand nearly all forms of attack. It can also use any of its three spiked tails to strike its opponents and break through most defences. In the anime, Isobu's only known physical weakness is its eye; as tough as its skin and shell are, it cannot harden its eyes and thus seems to keep one closed at all times.


Three-Tails Menacing Water Ball2

In the anime, Isobu's abilities were greatly elaborated upon. It could create shockwaves to repel attacks and produce large tidal waves around it, enabling it to overwhelm Guren's Crystal Release several times over the course of their battle. When Isobu ate something, thousands of miniature versions of itself would attack what was eaten within its stomach, presumably to speed up the digestion process. It was also shown capable of materialising an entrance to a separate dimension in which it could hide its presence, until it was ready to return to wherever it chooses.[11]

Nature Transformation

As a turtle, Isobu has an affinity for Water Release. In the anime, it could fire chakra-infused water balls that were powerful enough to destroy an entire cliff side.

Part II

Akatsuki Suppression Mission

In the manga, Tobi and Deidara confronted the beast around the same time Naruto Uzumaki had begun his Wind Release training, to which it responded by beginning to chase Tobi. With the Three-Tails distracted, Deidara moulded an explosive clay fish in an attempt to capture it. It was unclear if this marked the end of the battle, as the remainder of the battle went unseen. As the two towed the Three-Tails to the Akatsuki's lair after the battle, Tobi gloated at bringing the Three-Tails down with his special technique, but Deidara thought otherwise. It was later sealed in the sealing statue.

Three-Tails' Appearance

Main article: Three-Tails' Appearance

The dimension's entrance

The entrance to the dimension where the Three-Tails came from.

In the anime, Orochimaru instructed Kabuto Yakushi and Team Guren to take a young boy named Yūkimaru to a lake. After they arrived, Kabuto forced Yūkimaru to release all of his chakra, which caused the Three-Tails to begin to surface from the lake. With Guren's help, the beast was completely revealed, and they attempted to capture it. Their attempts proved insufficient, however, and the beast created a large tidal wave to wash its attackers away.

The tidal wave gained the attention of a nearby group of Konohagakure ninja, who tried to use Four-Corner Sealing Barrier to permanently trap the beast in its own dimension. Just as the sealing began to work, the Konoha ninja were interrupted by Guren, which prompted the beast to attack them all. Yūkimaru was able to calm the beast down temporarily, but, after he became tired, the Three-Tails turned its attention to him. Guren and Naruto Uzumaki came to his defence, but were swallowed in the process. With the help of their allies on the outside, they were able to escape, and the Konoha ninja tried once more to seal the beast.

Isobu captured by Akatsuki

Just when the sealing was almost complete, Yūkimaru, angered by the apparent death of Guren, empowered the beast to break free of its restraints. The Three-Tails went on a rampage, attacking everyone nearby and crushing Nurari, Kigiri, and Kihō. Its attempts to attack Yūkimaru, however, had no effect. It was only through the use of the Wind Release: Toad Oil Flame Bullet that the beast was driven away. The sealing attempt was left to Anbu members, and the remaining Konoha ninja returned home. Deidara and Tobi of Akatsuki soon found these Anbu members and disposed of them.

Fourth Shinobi World War: Climax

Biju full transformation

The remaining jinchūriki transform into their tailed beasts.

After Son Gokū is resealed into the Demonic Statue of the Outer Path, Tobi, who is intent on going all-out from this point on, forces Yagura to fully transform into the Three-Tails.[12] Preparing to attack the shinobi, the Three-Tails along with the other four beasts create Tailed Beast Balls. These attacks however, are deflected by Naruto and they are rebuffed by a now fully-transformed Naruto. Wasting no time in their attacks, the Three-Tails evades Kurama's attack and then, rolling into a ball, attempts to attack the beast while Saiken had incapacitated it. It is however stopped by Gyūki. Freeing itself from the beast's grasp, it and the other opposing beasts prepare a collaborative Tailed Beast Ball which is met by one from Naruto and Kurama.

Seishin Sekai

Isobu, alongside the other jinchūriki and tailed beasts, encounters Naruto.

As Naruto enters a deeper plane of the tailed beasts' consciousness, Isobu (who remembers meeting him in the anime) introduces itself to the young man. Later, as the beast is freed from the chakra receiver it affirms Kurama's belief that Naruto was the person the Sage of the Six Paths had spoken about so long ago before being resealed into the Demonic Statue of the Outer Path.

Birth of the Ten-Tails' Jinchūriki

Biju released

Isobu is released alongside the other tailed beasts.

Isobu appeared alongside the other tailed beasts with the exception of Gyūki and Shukaku when the Ten-Tails looked down at Naruto. The image of the tailed beasts, along with a silhouette of the Sage of the Six Paths, drove the Ten-Tails to a fit as it evolved further. Due to the combined teamwork of the Allied Shinobi Forces, Isobu, alongside the other imprisoned tailed beasts, was later pulled out of Obito and thus freed.

671 bijuu reunion

The tailed beasts reunite with Hagoromo and Naruto.

As Naruto in Tailed Beast Mode pinned Madara down with a tail, Isobu and the other tailed beasts joined in and did the same to increase the damage, but the Uchiha survived their attacks and retreated to a safe distance. After he received his own right Rinnegan eye from a White Zetsu clone, Madara quickly summoned the Demonic Statue of the Outer Path from Obito's body, and used the Rinnegan to repel the tailed beasts. With the tailed beasts stunned, Madara then proceeded to chain them up and prepared to seal them back into the statue. Ultimately, Isobu, along with the other tailed beasts, are all resealed within the Demonic Statue. Later, the chakra Isobu transferred to Naruto earlier manifested within Naruto's subconscious along with the other tailed beasts to speak with the young ninja and the spirit of Hagoromo Ōtsutsuki. There, they voiced their shared belief that Naruto was the child of prophecy.

Kaguya Ōtsutsuki Strikes

Ultimately, Kaguya Ōtsutsuki who had taken control of Madara was defeated by Naruto Uzumaki and Sasuke Uchiha and sealed using the Six Paths — Chibaku Tensei technique. The beasts were all ejected from the statue and then summoned back to the real world by Hagoromo and the previous Kage. After the past Kage return to the after life, the tailed beasts begin discussing their plans for the future now that they are finally free. Sasuke however makes his plans known. Desiring to kill the current Kage and seize control of the tailed beasts for his plans of revolution in the shinobi world, he quickly accomplishes the latter with his Rinnegan. With the tailed beasts subdued by his genjutsu, Sasuke then seals them away within his Chibaku Tensei. After the battle when Sasuke declared Naruto the victor, the two dispelled the Infinite Tsukuyomi and Sasuke released Isobu along with the other tailed beasts from their prisons.

In other media

Video Games

Although Isobu itself is not playable, Yagura takes on its form as his awakening in Naruto Shippūden: Ultimate Ninja Storm 3 and Naruto Shippūden: Ultimate Ninja Storm Revolution. Isobu also appears as a boss in Naruto Shippūden: Ninja Destiny 3.


  • 'Isobu' (磯撫) literally means 'beach stroker', and is also an adaptation of the name of the sea yōkai Isonade (磯撫で). The Isonade had a hooked tail, similar to Yagura's staff.
  • Since Rin died without having Isobu extracted, Isobu is the first known tailed beast to have "died" and revived.
  • In the Three-Tails' Appearance, Isobu's capture took place much later than in the manga, but played out in much the same way.
