Wood Release

The jutsu are techniques that combine earth and water-based chakra to create wood. Mokuton techniques can be produced from anywhere, including the user's body, as the user's chakra is literally converted into a source of life. The First Hokage was the originator of this ability, evidenced by the fact that none of his relatives have been shown capable of using Mokuton. The First's ability to use Mokuton was the reason for his being given the title of Hokage, and with he was able to grow the trees that served as the foundation of Konohagakure.

Orochimaru desired the First's Mokuton abilities, and injected the First's DNA into 60 test subjects in an attempt to replicate the ability. Yamato was the only test subject to survive, and is the only known living user of Mokuton. Yamato has been shown to be quite adept with the ability, and has performed a number of Mokuton abilities since his introduction. With the, Yamato can create a copy of himself made of wood to carry out tasks he is unable to do at the moment. He can also perform to create a half-dome used either to block attacks or capture others. The can serve a similar purpose, as it creates a large wooden cage with which to confine the opponent. Yamato has also been shown to use his abilities for creature comforts, such as using to create a house for him to camp out in.

A possibly unrelated technique, but unique to the First and Yamato, is the. This jutsu produces a seal (座, "seat") on the user's hand that can suppress a tailed beast's influence over its host. This is done by producing wooden dragons from the ground that attach to the host and force the tailed beast's chakra to recede. The First Hokage's crystal necklace aids in this technique's execution, but its exact role is unclear.
