Byakugan

The **Byakugan** (白眼, *literally meaning:* White Eye, *meaning (Viz):* All Seeing White Eye) is a kekkei genkai dōjutsu that originated from the Ōtsutsuki clan. After the Ōtsutsuki settled on Earth, the Byakugan became more commonly associated with the Hyūga clan, descendants of the Ōtsutsuki. It is regarded as one of the "Three Great Dōjutsu", the others being the Sharingan and the Rinnegan.

## Info

Unlike dōjutsu such as the Sharingan, which do not manifest until users meet certain conditions, the Byakugan is present from the time of birth. Individuals with the Byakugan are typically identifiable by their unique eyes: the irides are enlarged and white (light lavender in the anime), and there are no distinguishable pupils. When users activate their Byakugan, the pupils become more distinct and the increased blood flow to their eyes causes the veins near their temples to bulge. Some users' Byakugan take on atypical characteristics:

* Himawari Uzumaki is a descendant of the Hyūga clan through her mother, but ordinarily has the same blue eyes as her father. Her eyes become featureless white only while her Byakugan are in use.
* In *Itachi Shinden*, Mukai Kohinata's family split off from the Hyūga clan several generations before his birth, leading most to assume his bloodline was too diluted to possess the Byakugan. Mukai does in fact have a Byakugan, but only in his left eye and which only resembles a Byakugan when in use.
* Momoshiki Ōtsutsuki's Byakugan usually appear identical to any other Byakugan, but take on a golden colour after he absorbs Kinshiki Ōtsutsuki's power.
* Urashiki Ōtsutsuki's Byakugan, similarly to Momoshiki's, appears like any other, but also take on a golden colour after consuming the chakra he collected along his own eyes.
* Isshiki Ōtsutsuki only possesses one Byakugan, in his left eye; his right eye is seemingly a different dōjutsu.

The Byakugan's array of abilities have rendered it highly coveted. Kumogakure has made various attempts to acquire and study the Byakugan over the years, notably during the Hyūga Affair. Ao of Kirigakure was able to acquire a single Byakugan from a Hyūga he defeated, which he goes to great lengths to protect; unlike other dōjutsu that have been transplanted, Ao can activate and deactivate his Byakugan at will. When Danzō Shimura of Konohagakure learns of Ao's Byakugan, he makes immediate plans to either destroy it or take it for himself. In order to prevent the Byakugan from being acquired by enemies, the Hyūga clan developed a practice of applying cursed seals to most of its members; when those branded with the cursed seal die, their Byakugan are destroyed. The anime implies that simply possessing a Byakugan is not enough to be able to use its powers; even if one is born with visible traits of it, they must undergo intense training before the Byakugan's power can be activated, something not all users can accomplish. The anime likewise shows the Byakugan activating automatically if the user is under stressful circumstances, even if they haven't learned how to activate it on their own. Once a user does become able to use the Byakugan, they must avoid using it excessively, otherwise they will be rendered unable to keep it active until they've taken time to rest.
