The Earth Release (土遁, Doton, English TV: Earth Style) techniques are jutsu that use the surrounding ground, or earth for offensive and defensive purposes. Earth Release jutsu has the ability to change the hardness and composition of all objects. A person who masters this element can cause an object to be as solid as metal or soft as clay in his or her jutsu.
