After striking the ground with his hands, Jirōbō creates a large wall of earth in front of him. The defence is not perfect though, since a hard or drilling impact such as the Spiked Human Bullet Tank technique can puncture the wall. Also, since this technique only guards against frontal attacks, the enemy can easily attack from the side or even from above.
In the manga, when Jirōbō used the technique, he smashed the ground and forced it to form the wall via leverage. In the anime, the ground flipped upwards like a trapdoor.
After acquiring Jirōbō's DNA, Kabuto Yakushi gained the ability to use this technique through a doppelgänger of Jirōbō which emerges from the base of his navel snake; he used it to shift aside the earth that had been set ablaze by Amaterasu instead of defence.
