If you are wondering how old is Satoru Gojo, HariManga has the full breakdown. Gojo was born on December 7, 1989, making him 28 years old at the beginning of Jujutsu Kaisen in 2018 and 29 years old during the major December 24 arc. However, because of the time dilation effect inside the Prison Realm, Gojo experiences time differently than the outside world, creating a unique difference between his biological age and the real-time progression of the story.
Understanding Gojo’s age requires looking at both the in-story timeline and the impact of his sealing. Below is a clear timeline of how Gojo’s age fits into the events of Jujutsu Kaisen.
Gojo Satoru’s Official Birthdate
Gojo’s birthday is December 7, 1989, a detail confirmed through official character materials. This places him among the older adult sorcerers in the main series, though his youthful attitude and playful personality often make him seem younger.
How Old Is Gojo at the Start of Jujutsu Kaisen?
Jujutsu Kaisen begins in 2018, making Gojo 28 years old when Yuji Itadori becomes his student. At this stage, Gojo is already recognized as the strongest sorcerer alive and holds a teaching position at Tokyo Jujutsu High.
How Old Is Gojo When He Gets Sealed?
Gojo is 29 years old at the time he is sealed in the Prison Realm during the Shibuya Incident. His birthday passes just before the December 24 battle, so his age is firmly 29 at the moment of sealing.
How Time Dilation Affects Gojo’s Age
Inside the Prison Realm, time flows differently, meaning Gojo does not experience the full passage of time occurring in the outside world.
Physically and mentally, Gojo remains around 28–29 years old during the main events.
In real-world chronological terms, by late 2024 or early 2025, Gojo would be mid-30s if his age were calculated by actual elapsed years.
However, Jujutsu Kaisen canon treats Gojo consistently as 28–29 throughout the core events, because the story timeline moves much slower than real time.
Why Gojo’s Age Matters in JJK?
Gojo’s age highlights several narrative elements:
- He became the strongest sorcerer at a very young age.
- He carries immense responsibility despite being under 30 for most of the story.
- His maturity, wisdom, and combat experience contrast with his playful personality, adding depth to his character.
Whether he appears as an overpowered mentor or as someone still growing into his role, Gojo’s age plays a significant role in how fans understand his development.
Conclusion
So, how old is Satoru Gojo? He is born on December 7, 1989, making him 28 years old at the start of Jujutsu Kaisen and 29 years old during the Shibuya Incident when he is sealed. Although real-world years would place him in his mid-30s today, the story timeline keeps him locked at 28–29 because of Prison Realm time distortion.
