Overview of Jujutsu Sorcery’s Barrier System
- Jujutsu Sorcery relies heavily on barriers, which serve various functions and vary in complexity.
- These barriers are essential for domain expansions and provide protection to designated areas.
- Each barrier type, including curtain and bon barriers, is designed for specific purposes and demands different levels of skill to create.
Jujutsu Sorcery is intricately built on the principles of Cursed Techniques, derived from a user’s inherent cursed energy, enabling them to channel phenomenal abilities. At the heart of the power dynamics in Jujutsu Kaisen is the critical concept of barriers. These barriers range from basic forms that restrict entry to advanced implementations found in domain expansions, illustrating their versatility and significance.
In total, five distinct barrier types exist within Jujutsu Sorcery, each varying in complexity and strength. Barriers can either be simple, functioning to restrict access to certain areas, or complex, capable of executing powerful domain expansions. Instances of barriers are prevalent throughout the narrative, highlighting their fundamental importance in the mechanics of Jujutsu Kaisen.
The Role of Barriers in Jujutsu Kaisen
Barriers as Fundamental Constructs

In Jujutsu Kaisen, barriers represent zones crafted from cursed energy, primarily intended for area protection. Constructed using talismans and binding vows, their functionalities vary significantly based on the complexity of the conditions set for their creation. The process of generating intricate barriers can be daunting, even for adept sorcerers.
While basic barriers are relatively easily erected, constructing customized barriers with specific conditions—such as denying entry to certain individuals—requires unparalleled skill. These barriers not only shield users from enemy assaults but also serve critical purposes in overall strategy and defense. It’s essential to recognize that most barriers can be nullified by defeating the caster, although advanced barriers can endure even when their creator is incapacitated.
Understanding Domain Barriers
Essential for Domain Expansions

Within Jujutsu Kaisen, barriers serve multiple functions, with their most prominent application seen in domain expansions. A domain expansion is a manifestation of a user’s intrinsic cursed technique, created within a contained area initiated by a barrier. When a barrier is established using a sorcerer’s innate abilities and curse energy, along with a binding vow, it forms a complete domain expansion.
These barriers typically maintain a spherical shape, either suspended in the air or grounded, ensuring that those trapped inside find it exceedingly difficult to escape. Conversely, the integrity of these barriers is vulnerable, as experienced sorcerers can breach them from the outside, effectively dissolving the barrier’s effectiveness.
Anti-domain techniques and incapacitating the caster also represent feasible methods of dismantling these barriers. The complexity of barriers used in domain expansions is emphasized by their limited number—only fourteen have been documented in the series thus far, showcasing their challenging nature.
Curtain Barriers
Visual Barriers with Unique Functions

Curtain barriers serve as visual veils, designed to conceal certain areas from external view. These barriers are particularly utilized by Jujutsu sorcerers during the covert exorcism of cursed spirits but can also selectively permit or deny entry to individuals. Notable usage of curtain barriers was exhibited during the Kyoto Sister-School event, where Juzo erected a curtain allowing passage for some while prohibiting Satoru Gojo from entry.
Creating curtain barriers necessitates a level of skill that can range in difficulty, with more complex configurations reserved for highly experienced sorcerers.
Pure Barriers
Advanced Barriers Mastered by Tengen

Pure barriers are a superior form of barrier technique, recognized for their potency and extensive coverage. Tengen, a central figure in Jujutsu Kaisen, uniquely holds the capability to maintain these potent barriers, which are strategically positioned across Japan.
Among these barriers, four serve critical functions, such as deterring cursed spirits and enhancing the defenses established by Jujutsu sorcerers. Notable locations, such as the Tomb of the Star and the Imperial Palace, uphold significant importance due to their sanctity within the sorcerer community. Importantly, pure barriers do not obstruct other sorcerers or humans; their primary purpose is the containment of cursed spirits.
Exploring Empty Barriers
Non-Combat Vacant Zones

Empty barriers represent another category of barrier techniques, establishing zones that are predominantly devoid of content. Casters can freely manipulate these barriers by altering their shapes and boundaries, thus creating an adaptable environment for various uses, diverging from the infusion of any innate curse techniques.
Rather than serving as combat tools, empty barriers allow users to visualize and create any environment within their confines. A specific instance of this is when Kenjaku transformed an empty barrier into a movie theater setting to display his plans to Choso.
Bon Barriers
Intricate Constructs in the Culling Games

Bon barriers are some of the most elaborate barriers featured in Jujutsu Kaisen, introduced during the Culling Games arc orchestrated by Kenjaku. These barriers, constructed using existing pure barriers, signify an advanced level of strategy and complexity.
Tengen’s pure barriers served as the foundational base for these bon barriers, reinforcing them further. Tengen retains the power to dismantle these barriers but would face the consequence of relinquishing his other pure barriers, thereby losing control over the suppression of cursed spirits, potentially empowering them.
For those eager to immerse themselves in the intricate world of Jujutsu Kaisen, the series is readily available for streaming on Crunchyroll.
