Jutsu are considered the most powerful art a ninja will utilize in battle. To use a jutsu, the ninja will use his chakra and possible hand seals. The Chakra the ninja uses comes from two different places. (1) The body energy that is located in the millions of cells in the human body and (2) The energy gained from exercise and experience.
To use a Jutsu the ninja will have to learn to release both of the different types of energy. Hand Seals are the key to unlocking those energys, after doing the needed hand seals the ninja will use a jutsu. Because of the many different hand seals that would mean many different combinations, there are thousands of Jutsu that could be created with these combinations.
Controlling, Building, and Protecting!
||Controlling chakra during battle is one of the most important aspects in fighting. Another important part is to being able to build chakra to perform techniques. Building chakra is essential if you want to perform Genjutsu and Ninjutsu techniques correctly. Stamina also plays a big part in this. In order to create chakra you must convert it from stamina. When you perform techniques you not only release chakra but also stamina. Being unable to control your chakra can end up being deadly. If you release too small of an amount, the technique you tried to perform will fail. If you use too much chakra you may end up severely hurting or killing yourself. A ninja must have a certain amount of chakra in their body to live.|
||In addition to the circulatory system in your body to transfer blood, ninjas also has a circulatory system to transport chakra. Instead of having veins and arteries, chakra is transported from certain pipes and passage ways. Chakra is released by traveling through this system and out. Since the chakra circulatory system goes around many important organs, when the circulatory system is attacked and damaged your organs may be damaged as well. There are 361 openings in the chakra circulatory system in your body. This opening is called the Tenketsu. When the Tenketsus are blocked you will be unable to perform any techniques. The Byakugan has the ability to neutralize all the holes so chakra cannot flow. It is very important to protect yourself from these types of attacks.|
|Chakra gates are gates in the body that are used as limiters for chakra. They regulate the flow of chakra thoughout a person's body to prevent someone from going beyond his/her body's control. But by using a move like the Primary Lotus, which opens 3 gates, the user can release some of the limits on the body. This means the body can move at a much higher rate and with more power. Opening a gate increases chakra flow temporarily, but by doing this, it means the user puts an incredible amount of force on his/her body which can result in massive injury. There are 8 gates in a body. If all 8 are opened, the body no longer has any limits and can move as fast as it wants. But opening all 8 gates is often fatal and depending on the move, it can kill the user.|
|There are five different types of chakra: Fire, Water, Earth, Wind, and Lighting. The Uchiha clan tends to have the fire type of chakra, although Sasuke can use both lightning and fire. Kakashi is of the lightning type. Naruto is of the wind type. Most Jounin can use at least two types of chakra. Using two types of chakra at the same time is often a result of a bloodline limit. For Haku, he used water and wind types to create ice. Yamato uses earth and water to create wood. To find out the type of chakra a ninja uses they use paper from a tree that feeds off of chakra. If the paper splits you're type of chakra is wind, if it bursts into flames yours is fire, gets soggy its of water, the papper crumples if you are of lightning, and it turns to dust if you are of earth chakra.|
There are several different ways ninja are trained to learn to better use their Chakra. For each of these ways that have currently been revealed, we have given an explanation of what it is.
Tree Climbing: In this exercise, the user must gather Chakra at the bottoms of the feet, and then walk up a tree as if it were ground. If you have gathered too much Chakra you will break the tree and be thrown in the opposite direction. With too little Chakra, you will also fall. However, with the correct amount the user will actually stick to the tree. But, this is just the first step. Doing this for a matter of seconds is the "easy" part, sustaining it for minutes, or even hours is the true test.
Kakashi believed if his students could sustain it long enough to walk to the top of a tree they had learned this exercise and passed the test. Being able to do this successfully is a big step in learning to properly control and manipulate ones own Chakra.
Water Walking: Similar to Tree Climbing, think of this exercise as merely a more advanced version of the same thing. Like the Tree Climbing exercise, the goal is to gain better control and manipulation of one's own Chakra. Also like the Tree Climbing exercise, producing too much or too little Chakra will result in falling. The user must produce (and sustain), just the right amount of Chakra.
Unlike the Tree Climbing exercise, what you're walking on isn't a solid surface and is constantly moving! This means that exact amount of Chakra you need to produce is different then when on a solid surface, and may be different from time to time. When this is taught to Naruto, an extra part of the Kyubi seal is removed, giving Naruto much less restricted Chakra flow.
Leaf Concentration A related training exercise to Chakra Molding, Leaf Concentration will hone a Ninja's concentration ability. Therefore, only those who have worked hard at their ability to concentrate can become excellent Ninja. For generations Konoha ninja have practiced their concentration, and have used the Leaf Concentration exercise. To keep the mind from becoming distracted, a leaf is placed on the user's forehead to focus upon.
As explained by Naruto's early teacher Iruka in a flashback, the leaf emblem on the Konoha head protectors comes from this exercise. Iruka liked this exercise, and tried to show it to Naruto and three of his other students when he saw them having trouble concentrating. While trying to master the Rasengan Naruto thinks back to that lesson, and uses Iruka's advice help complete the 2nd stage in learning the Rasengan.
