Jujutsu Kaisen Season 2 what is the Prison Realm

Jujutsu Kaisen Season 2 has been introducing us to new concepts, theories, and conspiracies, which have been an enthralling experience for the viewers. An introduction of one such conceptual reality is the Prison Realm in Jujutsu Kaisen, a pocket dimension that is meant to trap Satoru Gojo and is an elaborate plan laid out by Pseudo-Geto and his allies – Mahito, Choso, Jogo, and Hanami. In this article, we will look at the Prison Realm as a cursed object and the process of sealing Gojo.

Jujutsu Kaisen Season 2 – the Prison Realm and its conceptual existence

The Prison Realm is a special-grade cursed object that works as a barrier that holds the capability to absolutely seal the target inside an inescapable pocket dimension. It is said to be the final remains of the Buddhist Monk Genshin and is referred to as a taboo object. This cursed object is a living barrier and it can seal anybody or anything. While it is dormant, it takes the shape of a small cube that can easily fit into the palm of an individual and is bounded and secured by talismanic restraints.

  • This realm is activated when the incantation “gate open” is spoken.
  • The cube opens into a fleshy mass that stretches out to four corners and the giant bleeding eye remains in the middle of it.

This eye is kept open with stitches to stare at the target. The conditions and stages for the Prison Realm to activate are as under:

  • This realm is placed in front of the target and must be within a four-meter radius.
  • The target should be held long enough for the cursed object to activate.
  • It opens and expands, proceeding to ensnare the target. The gates close and the sealing is complete.

How did the Prison Realm seal Satoru Gojo?

In Jujutsu Kaisen S2, the Prison Realm is the entire highlight of Pseudo-Geto’s plan. It was meant to seal Satoru Gojo and he convinced Mahito, Jogo, Hanami, and Choso to carry it forward. While they were aware that they couldn’t defeat Gojo, they also knew that if they bought enough time for the Prison Realm to activate, they might be able to seal him off and then proceed forward with their plan to get Sukuna as their ally.

  • The plan of sealing Satoru Gojo took place on October 31st in Shibuya. Mahito, Hanami, Jogo, and Choso worked together to keep him engaged.
  • While the battle went on, the Prison Realm suddenly appeared behind Gojo and the latter was met by the bloody eye.

While he was about to escape, Pseudo Geto revealed himself and it froze Satoru Gojo. The realm earned enough time to get a hold of Gojo and it sealed him off completely, taking its own time to process him but eventually sealing him nonetheless.

How does the Prison Realm look from the inside in Jujutsu Kaisen Season 2?

The pocket dimension is a boundless space that traps individuals in a frighteningly distraught environment with skeletons and an unsettling atmosphere. It has also been revealed that this dimension has two gates, a front and a back. The front gate is meant for sealing purposes while the back gate is meant for unsealing.

The unlocking process requires a cursed technique that nullifies other cursed techniques. This realm has no concept of time. Here, time doesn’t flow and therefore doesn’t pass.


The Prison Realm is a pocket dimension that is meant to seal any individual or person. It is a necessary tool to trap Gojo as the sorcerer is extremely powerful and cannot be trapped or stopped otherwise. The entire Shibuya Arc revolves primarily around this plan and the use of this cursed tool to imprison Satoru Gojo.
