Jougan Abilities

We've only seen glimpses of its true abilities, and at this time, Boruto still doesn't have complete control over it. Here's what we've learned so far: The Jougan, like the Sharingan and Byakugan, allows Boruto to sense chakra and visualize the pathway system.

Has the Jougan been explained?

The Jougan has been revealed to be able to see and sense chakra. In the Naruto franchise, chakra is the power used to form the attacks the ninjas use. Using his eye, Boruto has been able to track certain chakra signature. In the future, it may be possible for Boruto to use his eye to track anyone.
