Jougan is not considered a kekkei genkai.
While it is a unique and powerful dojutsu, it doesn't meet the criteria for a kekkei genkai. Here's why:
- Kekkei genkai are special bloodline limits that involve the combination of two chakra natures. Jougan, however, is not associated with any specific chakra nature combination. It is a unique dojutsu that operates on its own principles.
- Kekkei genkai are typically passed down through bloodlines and are not acquired through training. While Jougan's activation is triggered by specific circumstances, it is not a learned ability. It is inherent to the user.
Therefore, Jougan is a distinct dojutsu with its own unique characteristics and is not classified as a kekkei genkai.
