Jōgan

The Jōgan is a unique dōjutsu that is known only by the Ōtsutsuki Clan, whose members claim it's troublesome and that it's a power strongly inherited from their clan. In the manga the dōjutsu is featureless in appearance with a barely visible pupil. When depicted in the anime, the dōjutsu is light blue in colour with a darkened sclera and visible pupil.

When first used during his time in the Academy, Boruto did not appear to have the ability to activate it on command; instead, the eye would involuntarily activate when Boruto focused his attention on a particular person or object. As a teenager, he displayed the ability to activate it at will.

Abilities
Before gaining control of this dōjutsu, it would independently activate in the presence of dangerous/hidden targets. It can perceive the flow of chakra, enabling Boruto to see the visible changes in one's chakra and likewise track a target through their chakra. It can clearly see the chakra pathway system and even the Tenketsu. It can also see through invisible barriers that connect between dimensions, as well as predicting where Yomotsu Hirasaka will be used. Apparently, unique to other dōjutsu, the wielder retains full sight and access to its power even if the eye's natural state is damaged.

Trivia

 * After the airing of episode 15, Chengxi Huang, an animator for Boruto: Naruto Next Generations, made a blog post hoping to offer clarification to debating fans. The animator explained that the eye was neither a Byakugan nor a Tenseigan, and at the time was being referred to as a . He also explained that the eye is related to the Ōtsutsuki clan's dimension and its powers are the dōjutsu equivalent of Naruto's ability to sense negative emotions. However, he also noted that he personally hadn't read all the scripts and that this information was tentative and would be explained in detail in the future, and that fans should not think too much of it for now, as the author hadn't thought everything through himself. He included an illustration of Boruto putting eyedrops into his right eye, captioned.
