The Byakugan is a blood-line trait that appears in the Hyuuga clan. The user can see in a near 360 degree area except for a blind-spot located behind the neck along the spinal cord. The Byakugan eyes give their user a power similar to X-ray vision, allows them to see the flow of Chakra in another being's body, gives them telescopic vision, and the gift of insight; however they cannot use the insight on themselves.

An experienced Byakugan user can temporarily close off an opponent's various flows of chakra with carefully placed chakra blows, rendering the opponent unable to move the part of their body that was struck.
