In Boruto, Himawari accidentally triggers her Byakugan during a tantrum, instantly bashing out both Naruto and Kurama with a single punch. Meanwhile, Boruto watches from afar, his eyes lacking any noticeable change. This setting perfectly encapsulates a baffling riddle in the Next Generation series - why doesn't the protagonist inherit his mother's legendary white eyes?
The shocking truth that has divided the fanbase is that Boruto entirely lacks the Byakugan despite being Hinata's firstborn son. Unlike his sister, who easily shows the Hyuga clan’s iconic eye power, he possesses a unique dojutsu known as the Jougan. This genetic lottery has sparked much furor about bloodline inheritance and destiny in the shinobi world.
The Byakugan is defined as a formidable visual ability in the shinobi world. This "white eye" endows users with nearly full 360-degree vision, with only a small blind spot behind the neck. They can detect chakra flow, monitor targets from far away, and strike precisely using the lethal Gentle Fist technique.

Normally, Hyuga clan members inherit this ability innately. The Byakugan is the Hyuga clan’s trademark ability, handed down through their bloodline for generations. However, genetic inheritance doesn't ensure that every descendant will embody these powers.
Boruto has genes from two distinct bloodlines. His father, Naruto, hails from the Uzumaki clan, and his mother comes from the noble Hyuga lineage. This hybrid heritage forms interesting options but doesn't guarantee specific abilities.
Genetics work unpredictably, even within pure-blooded shinobi clans. Just as some Uchiha never gain the Sharingan, not all Hyuga inherit the Byakugan. He simply didn't inherit his mother's signature eye technique, while his younger sister Himawari successfully manifested it.

Rather than the standard Byakugan, he has the mysterious Jougan, or "Pure Eye." This uncommon dojutsu delivers different capabilities compared to his mother's inherited ability. The Jougan allows him to detect unusual chakra signatures, perceive dimensional portals, and identify threats that remain invisible to others.
Why Boruto Lacks the Byakugan
Several factors explain Boruto's lack of Byakugan abilities. First, genetic traits aren't guaranteed to be transferred between generations. Mixed bloodlines can produce unexpected combinations, with some abilities skipping individuals entirely.
The series creator initially overlooked giving him the Byakugan during early development. By the time this oversight was recognized, significant story elements had already been established. Instead of rewriting past lore, the story chose to highlight his distinct journey with the Jougan.

Additionally, his character development focuses on forging his own identity separate from his parents' legacies. Inheriting traditional Hyuga abilities might have overshadowed his individual growth and unique storyline.
Currently, no evidence suggests he will develop Byakugan abilities later in the series. His story arc continues, emphasizing the Jougan's development and its connections to larger cosmic threats. The narrative appears committed to this unique direction rather than traditional Hyuga powers.
However, anime and manga series often contain surprises. Future developments could theoretically introduce new power manifestations, though current storytelling trends suggest otherwise. His journey seems destined to explore uncharted territory rather than familiar clan abilities.
In the end, Boruto clearly lacks the Byakugan, even though he inherits Hyuga blood from his mother, Hinata. This genetic variation adds complexity to the series while allowing him to establish his own ninja way. The lack of Byakugan doesn't lessen Boruto's potential as a shinobi. His specific abilities open new storytelling possibilities.
