Jujutsu Kaisen: The Physics of the Culling Game Barriers Explained
I watched Jujutsu Kaisen Season 3 as it aired, and when the Culling Game arc started, I was confused. The barriers, the colonies, the rules—it felt like a lot to process. I went back to the manga to understand what was happening, and I realized the Culling Game barriers aren't just physical walls. They're something much more complex: a massive jujutsu ritual machine designed by Kenjaku to harvest cursed energy and force humanity's evolution. In this guide, I break down the "physics" of how these barriers work, why they're structured the way they are, and what Kenjaku's plan actually means for the series.
If you've been following jujutsu kaisen news or JJK Season 3, you've likely seen discussions about the Culling Game rules, the 10 colonies, and the mysterious "merger." The barriers themselves are the key to understanding everything. They use Bon Barriers—the most intricate type of barrier in the series—built on top of Master Tengen's pre-existing Pure Barriers. They function as a self-sustaining system that collects cursed energy, enforces rules through binding vows, and ultimately drives toward a catastrophic merger. Whether you're trying to understand the Culling Game mechanics, curious about why Hokkaido is excluded, or want to know how Kenjaku's plan connects to the series' finale, this guide covers the barrier architecture, the ritual mechanics, the energy dynamics, and the binding vow loopholes that make the game so dangerous.

What Are the Culling Game Barriers?
When I first saw the Culling Game barriers in Jujutsu Kaisen Season 3, I thought they were just walls that trapped players. But after diving into the manga and analyzing the mechanics, I realized they're much more than that. The barriers are a complex jujutsu ritual system—a machine designed to harvest cursed energy and facilitate humanity's evolution. They're not passive structures; they're active participants in the game, enforcing rules, collecting energy, and driving toward a specific end goal.
The barriers function on multiple levels. On the surface, they create isolated zones—the 10 colonies—where players fight and earn points. But underneath, they're part of a larger ritual that spans all of Japan. The energy collected from battles within the colonies powers a massive barrier that moves eastward across the country, "prepping" every human it passes over for the final merger. I think that's what makes the Culling Game so terrifying: it's not just a battle royale; it's a country-wide ritual that's already in motion.
Bon Barriers: The Foundation
The Culling Game uses Bon Barriers, which are the most intricate type of barrier seen in Jujutsu Kaisen. I've been analyzing barrier techniques throughout the series, and Bon Barriers are significantly more powerful than the standard "Pure Barriers" used by the Jujutsu Society. Here's how they work.
The Foundation: Hijacking Tengen's Pure Barriers
Kenjaku didn't build the barriers from scratch. Instead, he hijacked the four pivotal Pure Barriers maintained by Master Tengen—including those at the Imperial Palace and Mount Hida—to serve as the bedrock for the game. I think this is a crucial detail. Tengen's barriers were already in place across Japan, suppressing cursed spirits and maintaining the balance of the jujutsu world. Kenjaku essentially repurposed that existing infrastructure, turning a defensive system into an offensive ritual machine.
When I first learned about this, I was struck by the audacity of it. Kenjaku didn't just create new barriers; he corrupted the very foundation of Japan's jujutsu protection system. The Pure Barriers were meant to keep cursed spirits in check, but Kenjaku transformed them into a collection system for cursed energy. It's a perfect example of how he thinks: use existing systems, exploit their weaknesses, and repurpose them for his own goals.
The Architecture: 10 Connected Colonies
The 10 colonies form a literal line across the Japanese archipelago. I've seen maps of the Culling Game colony locations, and they're positioned strategically to create a secondary, extremely large boundary. This isn't random placement—the colonies are connected, forming a network that allows energy to flow between them and accumulate in the larger barrier system.
Each colony is an isolated zone where players fight, but they're all part of the same ritual machine. The energy collected in one colony contributes to the overall system, and the rules enforced in one colony apply to all of them. I think that's why the game feels so overwhelming: you're not just fighting in one location; you're participating in a country-wide ritual that's bigger than any individual battle.
Hokkaido Exception: The Sacred Zone
One detail that caught my attention is that Hokkaido is excluded from the Culling Game. I've seen a lot of questions about this—why is Hokkaido not in the Culling Game?—and the answer is that it's considered a "sacred zone" protected by its own long-standing Jujutsu Society barrier. Kenjaku couldn't hijack that barrier, so Hokkaido remains outside the game's influence. I think this is important because it shows that even Kenjaku has limits—he can't override every barrier in Japan, only the ones he can access and corrupt.
The 10 Colonies: Structure and Locations
The Culling Game has 10 colonies spread across Japan, each functioning as an isolated battle zone. I've been tracking the Culling Game colony map locations, and they form a line from west to east across the archipelago. Each colony has its own set of players, its own battles, and its own rules, but they're all connected to the larger ritual system.
I don't have the exact locations for all 10 colonies memorized, but I know they're positioned to create that secondary boundary I mentioned. The colonies aren't just random battlefields—they're strategic points in a larger barrier network. When players fight and die within a colony, the cursed energy released is absorbed by the barrier system and contributes to the eastward-moving boundary that's "prepping" humans for the merger.
If you're looking for a Culling Game colony map, I'd recommend checking the manga or official Jujutsu Kaisen resources. The locations matter because they show how the ritual is structured—the colonies aren't isolated incidents; they're nodes in a country-wide system.
The Ritual Mechanics: How Energy Is Collected
This is where the "physics" of the Culling Game gets interesting. The barriers function as a collection system for cursed energy, and the mechanics are surprisingly intricate. I've been analyzing how the ritual works, and here's what I've learned.
Energy Accumulation: The Harvest
As players kill each other within the 10 colonies, the released cursed energy is harvested by the barriers. I think this is the core mechanic of the ritual. Every death, every battle, every use of a cursed technique releases energy, and the barriers absorb it all. The more players fight, the more energy is collected, and the more powerful the ritual becomes.
The point system—5 points for a sorcerer, 1 point for a non-sorcerer—isn't just a scoring mechanism. It's a way to track how much energy has been collected. I've noticed that the game rewards killing sorcerers more than non-sorcerers, which makes sense from an energy perspective: sorcerers have more cursed energy, so their deaths release more power into the system.
The "Eastward" Movement: The Large Barrier
As cursed energy accumulates, an "extremely large barrier" starting from Japan's westernmost point is pushed eastward. I think this is one of the most fascinating aspects of the ritual. The barrier isn't static—it's moving, expanding, consuming the country as it goes. Every human it passes over is "prepped" for the final ritual, marked by the barrier system as a participant in the merger.
I've been thinking about what "prepped" means, and I think it's about connection. The barrier doesn't just mark people; it connects them to the ritual system, making them part of the energy network that will facilitate the merger. Once the large barrier reaches the boundary created by the 10 connected colonies, it conveys all those prepped humans to "the other side"—a state of formless existence modeled after Buddhist Nirvana.
Crossing the Boundary: The Vow
Entering a barrier signifies a "vow" to participate. This binding vow strengthens the barrier's ability to confine players, as it relies on the premise that they entered of their own free will. I think this is a crucial detail. The barriers aren't just physical walls; they're reinforced by the players' own consent. By choosing to enter, players implicitly agree to the game's rules, which gives the barrier the authority to enforce fatal penalties.
I've seen people ask why players can't just leave, and the answer is the binding vow. Once you enter a colony, you're bound by the game's rules. The barrier has authority over you because you consented to participate, and breaking that consent—by violating rules or trying to escape—triggers the lethal penalty of Cursed Technique Removal.
Binding Vows: The Loophole That Makes It Work
Kenjaku designed the Culling Game to be self-sustaining, and he did it through binding vows. I've been analyzing how these vows work, and I think they're the key to understanding why the game is so difficult to stop.
Voluntary Entry: The Consent Loophole
The barriers are reinforced by the premise that players entered of their own free will. I think this is a brilliant—and terrifying—exploitation of binding vow mechanics. In Jujutsu Kaisen, binding vows are more powerful when both parties consent. By making entry into a colony a voluntary act, Kenjaku ensures that every player has implicitly consented to the game's rules, which gives the barriers maximum authority to enforce penalties.
I've noticed that even players who are forced into the game—like those who were reincarnated against their will—still count as "voluntary" participants once they enter a colony. The barrier doesn't care about the circumstances that led to entry; it only cares that entry happened, which it interprets as consent. This loophole makes the game nearly impossible to escape, because the barriers have been strengthened by the players' own actions.
No Game Master: Self-Governing System
Kenjaku designed the game to be self-governing so that his own death would not end the ritual. I think this is one of the most important aspects of the Culling Game. The "Game Master" isn't a person; it's an AI-like protocol enforced by the Kogane shikigami. The game runs itself, enforcing rules, tracking points, and managing the ritual without any human oversight.
I've been thinking about what this means for stopping the game, and I think it's nearly impossible. Even if Kenjaku dies, the ritual continues. The barriers are self-sustaining, the rules are automated, and the energy collection happens automatically. The only way to stop it would be to destroy the barriers themselves, which is incredibly difficult given how powerful they are.
Game Rules and Mechanics
The Culling Game has strict rules enforced by the barrier system. I've been tracking the JJK Season 3 rules as they're revealed, and here's what I've learned about how the game actually works.
Automated Registration
Any non-player who enters a barrier is immediately registered as a player. I think this is one of the most dangerous aspects of the game. You don't have to sign up or agree to participate—just crossing the boundary is enough. I've seen characters accidentally enter colonies and get registered, which puts them at risk of the game's penalties.
Point System
Players earn points by ending lives—typically 5 points for a sorcerer and 1 point for a non-sorcerer. I've been analyzing why this system exists, and I think it's about energy collection. Sorcerers have more cursed energy, so their deaths release more power into the barrier system. The point values reflect that energy difference, incentivizing players to target stronger opponents.
Rule Negotiation
100 points allow a player to negotiate a new rule for the game, provided it doesn't significantly hinder its continuation. I think this is a fascinating mechanic. It gives players agency within the game, but only if they're willing to kill enough people to earn the points. The protagonists use this system to add rules that help them, like allowing players to transfer points or leave colonies, but even those rules are constrained by the barrier's requirement that the game must continue.
Forced Participation: The 19-Day Rule
Players must enter a colony within 19 days of awakening or face "Cursed Technique Removal," a fatal process that effectively destroys the brain. I think this is one of the most brutal rules. It forces participation—you can't just ignore the game and hope it goes away. If you're registered as a player, you have to participate, or you die.
Cursed Technique Removal: The Lethal Penalty
If a player breaks a rule—like not entering a colony within 19 days—they undergo "Cursed Technique Removal." I've been researching what this actually means, and it's terrifying. Because cursed techniques are engraved on the brain, "removing" them effectively destroys the brain, leading to certain death for the player.
I think this penalty is designed to be absolute. There's no way to survive it, no loophole to exploit, no technique that can counter it. Once the barrier enforces the penalty, the player dies. It's a perfect example of how binding vows work in Jujutsu Kaisen: the stronger the vow, the more absolute the penalty.
I've seen discussions about whether Reverse Cursed Technique could heal the damage, but I think the answer is no. Cursed Technique Removal isn't just physical damage; it's a fundamental destruction of the brain's structure. The technique is "engraved" on the brain, so removing it means removing part of the brain itself. Even if you could heal the physical damage, the technique would be gone, and the brain would be permanently altered. It's a death sentence disguised as a penalty.
The Kogane: The Automated Game Master
The Kogane shikigami functions as the automated game master, enforcing rules, tracking points, and managing the ritual. I've been analyzing how it works, and I think it's one of the most interesting aspects of the Culling Game. The Kogane isn't sentient; it's a protocol, a set of rules encoded into the barrier system. It can't be reasoned with, bribed, or manipulated—it just enforces the game's mechanics automatically.
I think this is why the game is so difficult to stop. There's no central authority to target, no person to defeat. The Kogane is part of the barrier system itself, so destroying it would require destroying the barriers, which is nearly impossible. The game is designed to be self-sustaining, and the Kogane is the mechanism that makes that possible.
Kenjaku's Plan: The Merger Explained
The ultimate goal of the Culling Game barriers is to generate enough energy to force all humans in Japan to evolve into a collective, formless state of existence without individuality—a concept inspired by Buddhist "Nirvana." I've been analyzing Kenjaku's plan, and I think it's one of the most ambitious and terrifying goals in the series.
The Merger: Humanity's Evolution
The "merger" is the final stage of Kenjaku's plan. Once the large barrier has passed over all of Japan and collected enough cursed energy, it will merge all humans with Master Tengen, creating a single, formless entity. I think this is inspired by Buddhist concepts of Nirvana—a state beyond individual existence, where all beings are united in a single consciousness.
I've been thinking about what this means for the series, and I think it's the ultimate expression of Kenjaku's philosophy. He sees individuality as a source of suffering, and he wants to eliminate it by merging all humans into a single entity. It's not about killing everyone; it's about transcending individual existence and achieving a state of perfect unity.
Tengen and Kenjaku: The Connection
Master Tengen is central to the merger. His barriers provide the foundation for the ritual, and his existence as an immortal, evolving entity makes him the perfect vessel for the merger. I think Kenjaku chose Tengen specifically because of his unique nature—he's already transcended normal human existence, so merging humanity with him would create a new form of being.
I've seen discussions about Tengen and Kenjaku merger mechanics, and I think the key is that Tengen's barriers are the infrastructure, but Kenjaku is the architect. Kenjaku designed the ritual, but he's using Tengen's existing barriers and his unique nature to make it possible. The merger isn't just about combining humans; it's about combining them with Tengen, creating something entirely new.
The "Other Side": Formless Existence
Once the large barrier reaches the boundary created by the 10 connected colonies, it conveys all the prepped humans to "the other side"—a state of formless existence. I think this is the most abstract part of Kenjaku's plan. The "other side" isn't a physical place; it's a state of being where individuality no longer exists, where all consciousness is merged into a single entity.
I've been analyzing what this means for the series' themes, and I think it connects to the Buddhist concept of Nirvana—a state beyond suffering, beyond individuality, beyond the cycle of birth and death. Kenjaku wants to force humanity into this state, whether they want it or not. It's not about enlightenment; it's about forced evolution, about eliminating the source of suffering by eliminating the self.
The Philosophical Implications
I've been thinking about what the merger means philosophically, and I think it's one of the most complex aspects of Kenjaku's plan. The merger isn't about killing everyone; it's about transcending individual existence. In Buddhist philosophy, Nirvana is the end of suffering, achieved by eliminating desire and the self. Kenjaku wants to force that state on everyone, creating a collective consciousness where individuality no longer exists.
I think this connects to the series' broader themes about suffering, existence, and the nature of humanity. Jujutsu Kaisen has always been interested in what makes us human, and the merger is the ultimate expression of that question. If you eliminate individuality, do you eliminate suffering? Or do you eliminate what makes life meaningful? I think that's the central conflict of the Culling Game arc—not just stopping Kenjaku, but questioning whether his goal is even desirable.
FAQ: Culling Game Barriers
What are the Culling Game barriers?
The Culling Game barriers are complex Bon Barriers that function as a massive jujutsu ritual machine. They're built on top of Master Tengen's pre-existing Pure Barriers and are designed to harvest cursed energy and facilitate humanity's evolution through the merger.
How do the Culling Game barriers work?
The barriers collect cursed energy from battles within the 10 colonies, powering a large barrier that moves eastward across Japan. This barrier "preps" every human it passes over for the final merger, where all humans will be merged with Master Tengen into a formless state of existence.
Why is Hokkaido not in the Culling Game?
Hokkaido is excluded because it's considered a "sacred zone" protected by its own long-standing Jutsu Society barrier. Kenjaku couldn't hijack that barrier, so Hokkaido remains outside the game's influence.
What is Cursed Technique Removal in JJK?
Cursed Technique Removal is the lethal penalty for breaking Culling Game rules. Because cursed techniques are engraved on the brain, "removing" them effectively destroys the brain, leading to certain death for the player.
How many colonies are in the Culling Game?
There are 10 colonies forming a line across the Japanese archipelago. Each colony is an isolated battle zone where players fight and earn points, but they're all connected to the larger barrier system that powers the ritual.
What is Kenjaku's plan in the Culling Game?
Kenjaku's plan is to use the Culling Game to collect enough cursed energy to force all humans in Japan to evolve into a collective, formless state of existence—a merger with Master Tengen inspired by Buddhist Nirvana concepts.
Can the Culling Game be stopped?
The game is designed to be self-sustaining, so even Kenjaku's death wouldn't stop it. The barriers are self-governing, enforced by the Kogane shikigami, and the ritual continues automatically. Stopping it would require destroying the barriers themselves, which is incredibly difficult.
Conclusion: Understanding the Culling Game's Physics
The Culling Game barriers are more than just walls—they're a complex jujutsu ritual machine designed to harvest cursed energy and force humanity's evolution. From the Bon Barriers built on Tengen's foundation to the binding vows that enforce participation, every aspect of the system is designed to be self-sustaining and nearly impossible to stop.
