Jōgan

The Jōgan is a unique dōjutsu that was awoken by Boruto Uzumaki in his right eye. Though the dōjutsu is mysterious to Boruto, Toneri Ōtsutsuki seemingly is aware of its capabilities and function. In the manga, this dōjutsu is featureless in appearance with a barely visible pupil. When depicted in the anime, the dōjutsu is 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 seemingly 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 determine its most key point. It can also see through invisible barriers that connect between dimensions.

Trivia

 * Chengxi Huang who is an animator for Boruto: Naruto Next Generations, posted a picture on his blog that shows Boruto cleaning his right eye. The caption of the picture reads and in the accompanying text, the animator elaborated that Boruto's eye was neither a Byakugan nor a Tenseigan. He also explained that the eye is related to the Ōtsutsuki clan's dimension and its powers is the dōjutsu equivalent of Naruto's ability to sense negative emotions. However, he then noted that all this information would be explained in detail in the future and fans should not think too much of it for now, as the author hadn't thought everything through himself.
