A shinobi is as strong as his strongest offensive techniques but as weak as his/her weakest defense.

What is 'Absolute Defense' we learn from Naruto? The power to possess a defense that cannot be breached by any attack.

In case you didn't know, let's take a look at the top 10 absolute defenses in the naruto.

10. 8 Trigrams Rotation

Using their near 360 degrees field of vision and x ray vision to their advantage, the byakugan wielder rotates using the leg as a central point.

They then knock off any weapon that pose a threat or could be thrown at them, despite the blind spot it has, it is durable enough.

As it was able to block strong weapons such as Kidomaru’s web enhanced spear.

9. Protective 8 Trigrams 64 Palms

Developed by hinata herself, this technique creates a net of chakra threads like lines in front of the user or where ever the user choose to create it.

It is very useful as it proved to be durable like a hard wall that blocks all the attacks against the user.

8. Amaterasu Flame Shield

The black flames can also be shaped as a defensive shield, just as Sasuke demonstrated with Itachi against kabuto, the black flames most offensive form, Enton Kagetsuchi .

which is the Hingest fire element jutsu can also be used for defense in this way, burning anything that could harm the wielder instantly before it can even pass through the fire shield.

7. kimmimaro dead bone pulse

The technique unique only to kimmimaro which allowed him to harden his bones as much as he wanted and they could be as hard as steel, even though most of the times in the anime it was shown offensively.

The fact that it could be harder than steel proves enough that it could indeed make the absolute defense.

6. Third Raikage Lightning Clad Armour

A technique that uses lightning enhanced chakra vibrating at very high speeds wich made it highly impenetrable such that the third was renowned to be carrying the strongest spear and the strongest shield.

But after it was rendered vulnerable to the third’s one fingered spear it seemed that it was Gaara who was possessing the strongest shield at the time.

5. Gaara Shield of Sand

A technique only unique to gaara, whenever he’s in danger a shield of sand comes to his aid.

It was had enough such that kimmimaru’s bones which where renowned to be harder than steel failed to scratch it, even the fire that was said to burn whatever that existed including fire itself, Amaterasu!,failed to burn and penetrate it.

4. Juubi/Bijuu Hide

This defensive form of tailed beast including the ten tails, is where the beasts use their tails to cover themselves completely.

It is quite durable as mentioned by obito when he said ten tails hide is tough.

Another testament to this is when the Gyuki and the Kyubi went against the juubi and used this technique to defend themselves against a very dangerous ray which had splitted numerous mountains before hitting them

3. Susano’o

The third technique that the mangekyo sharingan wielder unlocks, Susano’o, Sasuke called it the ultimate defense, madara called it the ultimate weapon that rivals even the tailed beasts, a nightmare, 

Those who sees it never lives to tell a tale, so he says, its shape transformation grants it more defensive and offensive form, with this one the more offensive it comes, also the more defensive it comes, absolute!!

2. Wood Release – Wood Locking Wall

We have never seen anything that has ever come close to breaking this technique in the anime, even for Yamato’s one that was way weaker compared to the first Hokage’s which was able to withstand a Susanoo enhanced tailed beast bomb with minor damages.

1. Truth seeking balls

This one can be used defensively or offensively, it is composed of chakra of all 5 elements, thus nullifying all ninjutsu, it is only vulnerable to senjutsu and taijutsu.

Besides, it is still a hard malleable chakra n requires more advanced taijutsu as the only thing that managed to break it was guy’s night guy 8 inner gates technique, it's quite an absolute defense.
