Jutsu Types
Ninjutsu refers to any technique that utilizes chakra and allows the user to perform actions that a normal person otherwise would be incapable of doing. Unlike genjutsu, which causes the opponent to experience illusions, the effects of ninjutsu are real and physical in most cases. Ninjutsu relies on chakra and, most of the time, hand seals to be effective.

Genjutsu are techniques that are employed in the same fashion as ninjutsu, requiring chakra and hand seals. However, the primary difference between the two is that the effects of genjutsu are illusory; instead of attacking the victim's body, genjutsu techniques manipulate the flow of chakra in the victim's brain, thus causing a disruption in their senses.

This is often used to create false images or to cause pain from trauma (because the body is led to believe it is in pain); however, there are plenty of other uses depending on the situation.

Taijutsu is a basic form of jutsu that typically does not require chakra, but chakra may be used to enhance techniques. Taijutsu generally require no hand seals to perform and are much quicker to use than ninjutsu or genjutsu. Taijutsu is simply put, hand-to-hand combat.

Sub Jutsu Types
Barrier ninjutsu is the incorporation of barriers into technique. Essentially these techniques allow the users to manipulate barriers. The user can erect barriers that can be used to protect themselves or to trap an opponent amongst other various uses.

Bunshinjutsu are techniques that create a copy of the user or objects used by them. The standard Clone Technique is considered the most basic of basic ninjutsu. Despite this, bunshinjutsu are very versatile and useful, and are often used to distract or fool enemies into thinking that they have delivered a critical or fatal hit to the user, leaving the enemy vulnerable. The various villages have created their own characteristic forms of bunshinjutsu. Besides these, there are a dozens of other bunshinjutsu in existence, some of which are extraordinarily difficult to use.

There are various methods of creating clones. The most commonly used bunshinjutsu use only chakra to create the clone. After these, bunshinjutsu that use a medium seem to be most common. These bunshinjutsu use various elements to give the clone form and substance. There are also bunshinjutsu that transform another person or animal into a clone of the user. Finally, there are bunshinjutsu that make use of Genjutsu to create illusionary clones.

A chakra absorption technique is a jutsu that allows the user to absorb an opponent's chakra. Some ninja, such as Yoroi Akadō and Jirōbō, are able to use this technique by merely coming into contact with an opponent, while most ninja require a medium to absorb chakra through.

Chakra flow refers to any technique that increases the potency of a weapon by flowing chakra through it. Usually, elemental chakra is used to flow through bladed weapons in order to either dramatically increase their various pre-existing properties or to gain additional advantageous effects. Although, another meaning of chakra flow can instead refer to the flowing of chakra through one's body, such as A's Lightning Release Armour, to increase close-quarter combat offence and defence. However, whether through an individual's body or weapon, the exact effects observed are entirely dependent upon the respective nature and amount of the chakra used.

Collaboration jutsu
Collaboration jutsu, also synchronized or combination jutsu, pertains to a branch of jutsu which entail powerful techniques that are actually comprised of at least two or more pre-existing jutsu. When initiated with the right timing, one will feed into each other to become a jutsu of greater power than the sum of its parts.

Flower Ninja Art is a subset of ninjutsu and genjutsu involving secret flower-oriented techniques used by a clan in the Land of Greens. The two known users of flower ninja art are Kikujō and Yurinojō. In several games, however, Ino Yamanaka makes use of jutsu resembling the Flower Ninja Art.

Fūinjutsu are a type of jutsu that seal objects, living beings, chakra, along with a wide variety of other things within another object.

Hiden jutsu are passed down from generation to generation in certain regions or clans. The groups possessing these techniques are usually extremely secretive about them. They ensure that no one other than the members of the group learn them. Only a few hiden jutsu require a special ability or lineage. These jutsu are usually the pride and fame of the clan that possesses them.

Juinjutsu are a type of jutsu used to bring someone under the control of the user. By applying a seal to the victim's body, the user brings the victim's abilities and actions under his/her control.

Kenjutsu pertains to techniques that entail the use of swords, whether the users be shinobi or samurai.

Kinjutsu are techniques that have been banned from being taught or used.

Nintaijutsu is a term used to describe the fighting style used by the Fourth Raikage. A combination of ninjutsu and taijutsu, the Raikage uses nintaijutsu by first surrounding himself with his Lightning Release Armour. This augments the strength of his physical attacks, making them more deadly.

Reincarnation Ninjutsu are techniques that require or accomplish the transfer of life force between people. Under normal circumstances, due to the death of a person being involved, such techniques are generally classified as kinjutsu. The restoration of one life typically requires the sacrifice of another.

Senjutsu refers to a specialized field of jutsu that allows the user to sense and then gather the natural energy around a person. Senjutsu practitioners can then learn to draw the energy of nature inside of them blending it with their own chakra (created from spiritual and physical energy within the shinobi), adding a new dimension of power to the sage's chakra, resulting in the creation of "senjutsu chakra". This chakra cannot be seen by anyone other than those who have been trained in senjutsu. This new chakra enables the user to enter an empowered state called Sage Mode, which can then drastically increase the strength of all ninjutsu, genjutsu, and taijutsu. A person who is able to use senjutsu is called a sage. It would seem that it stems from the toads of Mount Myōboku, as only Shima, Fukasaku, Jiraiya and Naruto have been seen using it. Gamakichi and Gamabunta also seem to be familiar with it.

Space–Time Ninjutsu are techniques that allow the users to manipulate the space–time continuum. By manipulating a specific point of space, the user can warp anything targeted into a dimensional void, and teleport it to another location instantaneously. Minato Namikaze, Madara Uchiha, and Tobirama Senju are all noted as skilled users in space-time ninjutsu.

A tailed beast skill is a unique ability or trait used by tailed beasts. These traits can vary greatly among the beasts, from nature transformations to concentrating chakra into extra limbs. The tailed beast's abilities can be transferred to its jinchūriki as a means of self-preservation, as if the host dies, the beast dies as well. These abilities can meld with the jinchūriki resulting in the beasts' power becoming their own. The ultimate technique that all tailed beasts share is the Tailed Beast Ball, which allows them to fire a concentrated blast of pure chakra, causing massive devastation.

Blood Limit Types
Kekkei genkai are abilities passed down genetically in specific clans. It's possible for a ninja to have more than one of these abilities. Kekkei genkai abilities that work via the user's eye are called dōjutsu. Other kekkei genkai include mixing one type of elemental chakra with another, creating a new one unique to the users, which is usually impossible for normal ninja.

Kekkei tōta is an advanced form of a kekkei genkai. The only known example is Dust Release, a combination of three different nature transformations.

Dōjutsu are genetic ninja abilities that utilize the eyes, enabling them to perceive chakra in some form or another. Being a by-product of specific kekkei genkai, dōjutsu are not classified as one of the major jutsu types. They do not require the use of hand seals and sometimes facilitate in the use or defence against genjutsu, taijutsu and ninjutsu and then defeat his or her opponent. All known dōjutsu also provide the user with some unique abilities, such as an extended field of vision or predictive capabilities. The use of Dōjutsu consumes chakra.
