Yuji Itadori is 15 years old at the start of Jujutsu Kaisen, and he remains physically a teenager even decades later due to anti aging effects tied to Sukuna, as discussed on HariManga. Many fans ask how old is Yuji Itadori because the series plays with time and biology. The main story establishes his age clearly, but later material adds a surprising twist. This guide explains his real age, physical age, and what changes across timelines.
Yuji Itadori Age in the Main Jujutsu Kaisen Story
In the main Jujutsu Kaisen series, Yuji Itadori begins the story at 15 years old. His birthday is March 20, 2003, which supports the timeline shown early on. This age is consistent with his first year high school setting and recruitment into jujutsu society.

During major arcs like Shibuya, he is still treated as a 15 year old by allies and enemies. His responsibilities become extreme, but his official age does not change quickly. The narrative emphasizes how young he is compared to the burdens he carries.
When readers search how old is Yuji Itadori, the simplest canon answer remains fifteen for most of the main run. He is written with teenage instincts, emotional swings, and growth through trauma. That characterization depends on him being a minor facing adult level stakes.
Yuji Physical Age Versus Chronological Age in Later Timeline
Later materials introduce the idea that Yuji’s body does not age normally because of Sukuna’s influence. This is described as an anti aging effect that halts physical development for decades. As a result, Yuji can remain physically teenaged even when much more time has passed.
In a time jumped sequel context often referenced as Jujutsu Kaisen: Modulo, Yuji is implied to be in his early eighties chronologically. However, his physical presentation stays close to a teenage body. This separation between calendar age and body age is the core reason the keyword keeps trending.
So if someone asks how old is Yuji Itadori in the newest time jumped setting, the accurate answer needs two parts. Chronologically he is decades older, roughly early eighties by that framing. Physically he still reads as a teenager because his growth effectively stopped.
Why Yuji’s Age Confuses Fans and How to Explain It Simply
Age confusion comes from mixing three different concepts: canon starting age, time passage, and body preservation. The main series gives a straightforward number, which is why many answers say fifteen. Later continuity complicates that number without changing his outward appearance.
A simple explanation is that Yuji’s official starting age is fifteen, and his birthday anchors that fact. Then supernatural biology linked to Sukuna prevents normal aging. The story uses this to explore identity, humanity, and what it means to live beyond your natural span.
For SEO clarity, the best response to how old is Yuji Itadori is to state the main series age first, then add the later distinction. In the main story he is fifteen years old. In the time jumped sequel framing he is chronologically in his early eighties but physically still teenaged.
Conclusion
Yuji Itadori is 15 in the main Jujutsu Kaisen timeline, with a March 20, 2003 birthday confirming that age during key arcs like Shibuya. Later time jump material suggests he becomes chronologically much older, roughly in his early eighties, while remaining physically teenaged due to anti aging effects connected to Sukuna. This is why the question how old is Yuji Itadori has more than one correct sounding answer depending on context. For quick accuracy, lead with fifteen for the main series, then add the later physical and chronological split, as summarized here on HariManga.
