Nature Transformation

is an advanced technique for manipulating chakra. While form transformation changes the shape and movement of chakra, nature transformation changes the actual nature of the chakra, altering its properties and characteristics.

Basic Types
There are five basic types in which the nature of chakra can be transformed, called the

These five types are also called elements and are not only the origin of the names of the Five Great Shinobi Countries, but also the foundation of all Ninjutsu.

These elements allow for elemental Ninjutsu to be performed. Fire natured chakra allows for Ninjutsu, Wind natured chakra allows for  Ninjutsu, Water natured chakra for  Ninjutsu, Lightning natured chakra for  Ninjutu, and Earth natured chakra for  Ninjutsu.

The five basic natures are all connected to each other in a circle, each being weaker then one and stronger then another. Fire nature is weak against Water, but strong against Wind. Wind is weak against Fire, but strong against Lightning. Lightning is weak against Wind, but strong against Earth. Earth is weak against Lightning, but strong against Water. Water is weak against Earth, but strong against Fire. Basically this means that if an elemental jutsu is put against an elemental jutsu of the same level, but of a stronger nature, then the stronger natured jutsu will prevail. However, a weaker natured jutsu can overpower a stronger natured jutsu if the weaker natured jutsu is of a higher level.

In general, every person has a chakra that has an affinity towards one of these types, a characteristic that seems to be genetic, since whole clans sometimes share the same affinity. Most members of the Uchiha clan, for example, had an affinity towards the Fire nature. To find out what affinity someone has, special pieces of paper are used that react to even the slightest hint of chakra in any of a number of ways, depending on the nature latent in the chakra.

This affinity makes it easier to learn how to create and control the nature in question, although even with an affinity this progress will usually take any number of years. Shinobi are not limited to the nature they have an affinity to, though. By the time they reach the rank of Jonin, most shinobi have mastered two natures. However, because of the difficulty of mastering a nature and the time required to learn it, it is almost impossible to master all five natures.

Advanced Types
Besides the five basic nature types, there are several more advanced types. By using two basic types simultaneously, one can create a completely new nature with unique properties. This is not something every shinobi can do, though. Only those people who have certain Kekkei Genkai have this ability.

So far, two advanced natures have been shown:


 * The nature used by Haku is created by simultaneously using the Water and Wind natures. This nature allows for the use of  Ninjutsu.
 * The nature used by the First Hokage and Tenzo is created by simultaneously using the Earth and Water natures. This nature allows for the use of  Ninjutsu.

There have also been two other possible advanced natures. The first is used by the Third Kazekage, who had special magnetic chakra unique to him, allowing him to use his signature Iron Sand techniques. The second is used by the Four-Tailed Beast and his Jinchūriki and allows them to use Ninjutsu.

Yin and Yang
Aside from the five basic types of nature transformation, there is also a sixth type: the transformation of the and  nature of chakra. Not much is know about this so far, except that it seems to allow certain otherwise non-elemental jutsu like Shadow Imitation Technique, Multi-Size Technique, medical Ninjutsu, and Genjutsu.
