The user converts chakra in their body into an earthen material that they spit from their mouth; the more skilled the user, the greater the volume of earth can then be created. The earth quickly piles up into a defensive wall, blocking incoming attacks. Although the muddy material is solid on its own, it is further fortified with a coat of chakra, making it more resistant to fire and water than it would otherwise be.
Kakashi's use of this technique differs from that of the Third Hokage in several ways. Rather than spit out the materials for the wall, he manipulates pre-existing earth. Additionally, his wall is brick-structured and composed of bulldog sculptures. The greatest difference is in its function: instead of creating the wall to defend himself, Kakashi forms it behind an opponent to box them in and prevent escape. In the anime, this technique can also be used to produce a series of constricting walls to encase a target.
- In Naruto Shippūden: Dragon Blade Chronicles, the Dragon Blade enables the user to perform this technique.
