Byakugan

The is a genetic trait that is shared amongst the members of the Hyuga Clan. Those that inherit the blood of this clan have almost featureless white eyes (Neji's and Hinata's eyes seem to have tints of lavender and blue-gray, respectively). Although it is not stated directly, it is assumed that all members of the Hyuga family possess the Byakugan. It is a common, but not proven belief that the Sharingan is a genetic offshoot of the Byakugan.

Abilities
The Byakugan is the primary focus of the Hyuga's special arts. When the Byakugan is activated, their pupils become more distinct and the veins near their temples bulge. Once active the Byakugan gives the user a near 360º field of vision except for one blind spot at the back of the neck above the third thoracic vertebra. They also have the ability to see through solid objects, and can use a degree of telescopic sight. The distance and the degree of telescopic sight varies from person to person. In Part I, Neji Hyuga was able to see an area of 50 meters, but later he increases his visual range to at least 800 meters. During the hunt for either of the Uchiha brothers, Hinata was shown to be able to view Amaterasu's flames and the chakra in the area from ten kilometers away.

However, one of the greatest uses of be sealed, stopping the chakra flow to those areas. Most of the Hyuga clan cannot even perform this because the Tenketsu are too small to see. Neji Hyuga is the rare exception, having taught himself the ultimate Hyuga technique, Eight Trigrams Sixty-Four Palms, along with Hinata Hyuga, who was not able to do 64 palms like Neji, but she is able to do Eight Trigrams 32 Palms, an slightly weaker version of Neji's, albeit only in the anime. Able to strike without force, and yet do more damage to a ninja than some of the most powerful Ninjutsu, the Gentle Fist is the greatest Taijutsu style known in all of Konohagakure.
