The Culling Game in Jujutsu Kaisen is a massive death-game ritual set up by Kenjaku: a battle royale where sorcerers and newly awakened players are forced to fight and kill each other inside barrier “colonies” across Japan to fuel a huge cursed-energy ritual and evolve humanity.

What is the Culling Game in JJK?

At its core, the Culling Game is a lethal tournament that starts right after the Shibuya Incident, framed as jujutsu terrorism on a national scale.

Kenjaku uses it to turn Japan into one giant ritual site, using the cursed energy produced by players killing each other to merge humanity with Master Tengen and create a new form of being.

In-story, that means:

  • People across Japan suddenly awaken cursed techniques and are told they must join the game or die.
  • Ancient sorcerers from Sukuna’s era are resurrected into modern bodies and also thrown into the game as powerful “players.”
  • Ten huge barrier “colonies” are erected across Japan, and all the fighting happens inside them.

You can think of it like a supernatural battle royale: once you enter a colony and accept, you’re locked into a game with strict rules, a points system, and constant pressure to keep fighting.

Basic rules (simple version)

The rules are intentionally complicated in the manga/anime, but the gist is:

  • After awakening a cursed technique, a person must enter a colony and declare participation within 19 days, or their technique is removed in a way that is likely fatal.
  • Anyone who enters a colony and agrees becomes a player on the spot.
  • Once inside, you’re stuck as a participant, and a Shikigami-like interface tracks your points and rules.
  • Players earn points by killing other players: sorcerers are worth more points than normal awakened civilians.
  • If a player doesn’t score enough points within a set time, they face removal of their cursed technique, which is implied to kill them.
  • Players can add new rules to the game by spending points, as long as those rules don’t interfere with the core ritual or allow everyone to just walk away.

This creates a constant pressure loop: fight, kill, gain points, and manipulate rules, or be killed by the system.

Why Kenjaku created it (story purpose)

Kenjaku’s real goal isn’t just chaos; it’s a ritual to reshape humanity.

  • The Culling Game funnels insane amounts of cursed energy from deaths and battles into Tengen’s barrier system.
  • That energy is used to forcibly merge Tengen with the entire population of Japan instead of just one Star Plasma Vessel, turning millions into a single, twisted cursed-energy “being.”
  • Kenjaku believes this will “evolve” humans beyond the usual limits of sorcerers and curses.

Because of binding vows Kenjaku took on himself, killing him alone doesn’t instantly stop the game once it’s started, which is part of what makes the arc so grim.

Where it fits in JJK (anime/manga context)

  • The Culling Game arc happens after the Shibuya Incident arc, which is where Gojo gets sealed and Japan is thrown into chaos.
  • It’s a long, complex arc full of multiple colonies (Tokyo, Sendai, etc.), each with its own mini-bosses and fights.
  • Yuji, Megumi, Yuta and others enter the game both to save people like Tsumiki and to add rules that can help free Gojo and disrupt Kenjaku’s plan.

Because Season 3 of the anime is focused on the Culling Game, it’s a big talking point in current fandom and forums right now.
