Unsealing Technique

This technique is a standard ninja skill which allows a ninja to summon an assortment of items that have been stored using fūinjutsu. Scrolls are the most common choice for item storage. When needed, the owner will activate the seals releasing their item or weapon of choice. Scrolls can also be used as ammunition for other weapons or have other seals inside of them, which expands the number of potential tricks a shinobi can use.

Weapons are the most commonly sealed objects. Toroi of Kumogakure for example, uses this technique to store his magnetised shuriken which he uses in battle. Puppet masters also use this technique with their puppets either through hidden scrolls in various compartments or a simple seal as a means of increasing their own killing potential as well as hiding useful weapons from the opponent's sight. This can be seen with Sasori's Thousand Hands Manipulation Force.

A wide variety of other things can also be stored in scrolls, to be released when the scroll is opened or under a specific condition. In the manga, this is done with the Water Prison Technique by Kisame Hoshigaki. Along with a medium for his sharks, it was used effectively as a trap, immobilising the persons that tried to read the scroll. In the anime this is seen when Shikamaru summoned a large amount of water, and Tenten's Exploding Dragon Strike technique.
