Hyūga Clan

The is one of the oldest and most powerful clans in Konohagakure. All members born into the family possess the Byakugan, a kekkei genkai that gives them extended fields of vision and the ability to see chakra. The Uchiha clan's Sharingan is believed to be descended from the Byakugan.

The clan is separated into two parts, the and the, a system that protects the secrets of the Byakugan from outsiders. The main house runs the family while the branch house protects it. The members of the branch house are branded with a cursed seal. This seal gives the main house members absolute control over the branch members, because they can destroy the branch members' minds with a simple hand gesture, or cause them great pain to punish them. This seal also makes sure the secret of the Hyūga's Byakugan is safe, because it seals the Byakugan after the wearer of the seal dies. Because they are essentially servants, simply because of their birth order or heritage, some branch house members are hostile to those of the main house. After the Chūnin exams in part I, the two houses have managed to at least start working out their differences. In Part II, they finally brought the two Houses together as a family, which they showed when the Hyūga battled Pain in a show of family unity.

Members of the clan are instructed in the use of the Gentle Fist style, which uses the Byakugan to view the opponent's Chakra Pathway System and deal precise blows to disable and impede the flow of chakra. Due to training in this style, Hyūga clan members tend to have excellent chakra control. This is emphasized in jutsu that utilize this chakra control, as well as the nuances of the Gentle Fist style. The clan's strongest techniques, like the Eight Trigrams Sixty-Four Palms, are only allowed to be taught to members of the main house. Neji Hyūga, however, has bypassed this restriction by learning them on his own, earning a reputation as a "genius" in the clan.

Trivia
שבט האיוגה
 * means "Towards the Sun", and is the name of a city in the Miyazaki Prefecture in Japan.
 * The name "Eight Trigrams" is a reference to the Chinese martial art Baguazhang, a fighting style usually made up of circular movements, allowing the practitioner a wider range of motion and full use of momentum, without giving his or her opponent much of a chance for a direct strike. In Japan, it is known as Hakkesho.
 * Ao of Kirigakure has defeated a member of the Hyūga clan, and took the member's Byakugan and transplanted into his right eye.
 * The Rinnegan seems to have a trait with the Byakugan which is to see from long distances and see someone's chakra points as pointed out by Pein in his battle against Jiraiya.
