Satoru Gojo is 28 years old at the start of Jujutsu Kaisen and 29 when he dies. He was born on December 7, 1989, and the main story begins in 2018 before his birthday passes that year . That single date explains why search results disagree, because his age depends entirely on which arc you are watching.
The confusion is understandable. Gojo appears at radically different points in his life across the anime and manga, from a cocky teenager in the Hidden Inventory arc to a seasoned teacher in Season 1. Each appearance carries a different number, and fans often mix them together when asking how old is Satoru Gojo at any given moment .
The earliest extended look at Gojo comes in the Hidden Inventory arc, adapted in Season 2. The events take place in 2006, when Gojo is a second-year student at Tokyo Jujutsu High. He is 16 years old during his fight with Toji Fushiguro, since his December birthday has not yet arrived that year .
A decade later, Gojo appears as a teacher in the prequel film Jujutsu Kaisen 0. The movie is set in 2017, roughly one year before the main series. Gojo is 27 for most of that story, turning 28 after December 7 passes within the film’s timeline .
The main series picks up about six months after the events of Jujutsu Kaisen 0. Season 1 begins in 2018, and because Gojo’s birthday falls late in the year, he remains 28 throughout the early arcs. That includes the Cursed Womb arc, the Kyoto Goodwill Event, and most of the Shibuya Incident .
By the time of the Shinjuku Showdown, the final battle against Ryomen Sukuna, Gojo has turned 29. Multiple entertainment outlets confirm he dies at that age, though the manga does not pause the action to announce a birthday chapter . The number is calculated from the established birth date and the story’s internal calendar.Quick Bio: Satoru Gojo
Notes on verification: Gojo’s exact birthplace is not established in canon materials. His age reflects the main 2018 timeline and the December birthday calculation. “Net worth” is unavailable as a precise figure; the creator’s salary comparison is the closest verified statement. Voice actor awards are attributed to Yuichi Nakamura’s performance, not the character himself.
One persistent source of disagreement online involves Wikidata, which lists Gojo’s birth date as December 7, 1987 rather than 1989 . That two-year discrepancy would make him 30 or 31 in the main timeline, which contradicts the widely cited 1989 date used by outlets like TheGamer and The Escapist . The 1989 date is the one consistently supported by anime journalism and timeline breakdowns.
Another factor is that Gojo’s age is effectively frozen after his death. Fans sometimes ask how old he would be in the present day, but within the narrative he remains 29 permanently. That detail matters for readers who encounter wiki pages or social posts calculating a real-world age and wonder why the number keeps climbing.
For a quick comparison, Gojo is significantly older than his students. Yuji Itadori is 15 when the series begins, and Megumi Fushiguro and Nobara Kugisaki are the same age. That roughly thirteen-year gap shapes their dynamic, with Gojo acting as a mentor who is young enough to understand their struggles but powerful enough to seem impossibly distant .
Gojo’s age also matters because it underscores how early he achieved his reputation. He was already called the strongest sorcerer as a teenager, and by 28 he had spent over a decade as the Jujutsu world’s most feared weapon. His youth relative to his power is part of what makes his character so unsettling to the higher-ups he opposes.
The simplest answer, then, is this. Satoru Gojo is 28 for most of Jujutsu Kaisen and 29 when he dies. His birth date is December 7, 1989, and any other number you see online either refers to a different arc, a different timeline, or a source that has mixed up the years.
Gojo Satoru was born on December 7, 1989, making him 28 years old at the start of the main Jujutsu Kaisen storyline and 29 at the time of his death. The main story begins in 2018, and since his birthday falls in December, he remains 28 for most of Season 1 and the Shibuya Incident arc .
He is 16 years old during the Hidden Inventory arc and 27 during Jujutsu Kaisen 0. The Hidden Inventory arc takes place in 2006, when Gojo is a second-year student at Tokyo Jujutsu High . The prequel film Jujutsu Kaisen 0 is set in 2017, roughly one year before the main series, where Gojo appears as a 27-year-old teacher .
Gojo turns 29 by the Shinjuku Showdown arc. After his December birthday passes within the story’s timeline, he is 29 during his final battle against Ryomen Sukuna . Multiple timeline breakdowns confirm this age progression from 28 to 29 across the main narrative .
Some sources list conflicting ages because they mix different arcs or use incorrect birth years. Wikidata and certain wikis have cited December 7, 1987, which would make him two years older, but anime outlets like The Escapist and The Mary Sue consistently use the 1989 date . The discrepancy often comes from calculating his age in real-world years rather than within the story’s internal timeline.
Gojo is significantly older than his students, with Yuji Itadori being 15 at the series start. That roughly thirteen-year gap shapes their mentor-student dynamic, positioning Gojo as a young but overwhelmingly powerful figure in the Jujutsu world . His age also underscores how early he achieved his reputation as the strongest sorcerer.
