Eight Gates

The Eight Gates are eight specific points on a person's Chakra Pathway System. They limit the overall flow of chakra within a person's body. The basis for the idea of the chakra gates comes from the body's limits on the functions within it. This makes the body much weaker, but it keeps the body from expiring too soon. By opening these gates, the user can surpass their own physical limits at the cost of extreme damage to their own bodies.

Rock Lee is able to open the first five gates. Might Guy, who taught Lee the skill, is able to open at least six. Kakashi can open at least one gate, as shown during Kakashi's one-handed rock climbing where a shot of his brain shows the relevant point activating, as well as in his usage of the Front Lotus.

The state of having all Eight Gates open is known as. Any shinobi who activates this state will temporarily gain powers greater than a Kage, but they will die because of the damage done to their body. However, in Naruto Shippūden 2: Bonds, Shinnō managed to use a technique that allowed him to open all the gates without any drawbacks.
