How Old Is Satoru Gojo?

Gojo is 28 for most of the main Jujutsu Kaisen storyline in 2018, and he turns 29 after December 7, 2018. His birthday is December 7, 1989, which is the anchor that makes every arc and flashback easy to calculate.

This matters because Jujutsu Kaisen frequently jumps between 2006, 2017, and 2018. If you read the manga on ComicK and bounce between arcs like Hidden Inventory and the present-day story, it is very easy to lose track of what year you are in. The guide below pins Gojo’s age to the timeline so you can always know which version of Gojo you are looking at.

How Old Is Satoru Gojo? The quick answer you can quote

Here is the simplest way to state it accurately for SEO, for forums, and for quick explanations:

• Satoru Gojo was born on December 7, 1989.
• In 2018 before December 7, Gojo is 28.
• From December 7, 2018 onward, Gojo is 29.
• In Gojo’s Past (Hidden Inventory) set in 2006, Gojo is 16 for most of the arc (he turns 17 after his birthday later that year).
• In Jujutsu Kaisen 0 set in 2017, Gojo is 27 before Dec 7 and 28 after Dec 7.

That is the full logic. Everything else in this article simply maps that logic onto specific arcs and dates so you do not have to guess.

Why people keep getting Gojo’s age wrong

Most confusion comes from three common habits:

People assume the present-day story spans multiple years

In reality, many of the biggest “present-day” events cluster within a relatively short window. A lot happens, but not across a long stretch of calendar time.

People mix up the prequel, flashback, and main series

Jujutsu Kaisen 0 is set before the main series, and Hidden Inventory goes back even further. If you read chapters out of order or jump between arcs on ComicK, your brain naturally averages details like age unless you anchor the year.

People quote different points in 2018

If someone is mentally anchored to Shibuya, they will usually say 28. If someone is anchored to late-December events, they will often say 29. Both can be right depending on which date they are referencing.

Gojo’s birthdate and what it implies across the timeline

Gojo’s birthday, being December 7, is crucial because it sits at the end of the year. That means:

• For almost the entire year, he is the age he turned the previous December.
• Near the end of the year, he increments by one, and the fandom immediately splits into two “correct” answers depending on whether the speaker is thinking pre-birthday or post-birthday.

A practical way to remember it:

If you are in any part of 2018 before early December, Gojo is 28.
If you are past December 7, 2018, Gojo is 29.

Gojo’s age in the main Jujutsu Kaisen story (2018)

When most readers ask “how old is Gojo,” they mean the Gojo who teaches Yuji, Megumi, and Nobara, the Gojo who dominates early battles, and the Gojo whose presence reshapes the modern jujutsu world.

That Gojo is living in 2018.

Early 2018 and the “teacher Gojo” era

Across the early arcs, Gojo is 28. This is the version of Gojo most anime viewers first meet, and it is why Gojo feels like such an unusual mentor archetype. He is not a grizzled veteran in his forties or fifties. He is a young adult, operating at the absolute peak of power, and teaching students who are still teenagers.

That gap matters narratively because it changes how you interpret his behavior:

• His humor and teasing land differently when you realize he is not that far removed from being a student himself.
• His impatience with bureaucracy reads as a clash between a late-20s powerhouse and an old system, not a generational mentor calmly guiding a new era.
• His ambition to reform jujutsu society feels urgent rather than philosophical.

Gojo’s age during the Shibuya Incident

The Shibuya Incident begins on October 31, 2018. On that date, Gojo has not reached his December 7 birthday yet, so he is still 28.

This is one of the most important anchors because Shibuya is a common reference point in discussions. If someone says, “Gojo is 28,” they are often implicitly referencing Shibuya without stating it.

Gojo’s age after his birthday in 2018

Once the timeline passes December 7, 2018, Gojo becomes 29.

This is where many online answers drift into contradiction, because readers remember “2018 Gojo” and default to 28. But late-December story beats occur after his birthday, so the correct age becomes 29.

A clean way to phrase this in your own content:

• Gojo is 28 through Shibuya and most of 2018.
• Gojo turns 29 in early December 2018.
• Any late-December 2018 event places him at 29.

Gojo’s age in Hidden Inventory (Gojo’s Past) set in 2006

Hidden Inventory is the arc that shows Gojo and Geto as students, before the modern status quo locks into place. The arc is set in 2006, when Gojo is a second-year student.

Because Gojo was born on December 7, 1989, he is:

• 16 for most of 2006 before December 7
• 17 after December 7, 2006

Most readers refer to him as 16 in this arc, and that is a safe shorthand for the majority of conversations.

Why “16-year-old Gojo” is the right mental model

Calling him “16-year-old Gojo” is not just trivia. It explains the tone of his confidence and the rawness of his worldview.

In Hidden Inventory, Gojo often reads like someone who has never been forced to accept limits. That is exactly what he is: a teenager at the peak of talent, protected by power and status, until the arc forces him to face consequences that do not care about talent.

When you treat him as a teen rather than “adult Gojo with a different outfit,” the character development becomes much easier to track:

• His arrogance becomes less “annoying mentor behavior” and more “untested prodigy behavior.”
• His bond with Geto feels like a peer relationship rather than a professional partnership.
• His later adult fixation on reform feels like a scar that formed early, not an ideology that appeared out of nowhere.

Gojo’s age in Jujutsu Kaisen 0 (set in 2017)

Jujutsu Kaisen 0 occurs in 2017, which places Gojo one year before the main series.

With his birthdate on December 7:

• Before Dec 7, 2017: Gojo is 27
• After Dec 7, 2017: Gojo is 28

If you see two different answers online, this is why. They are often both trying to be precise, just anchored to different months in 2017.

A practical way to talk about Gojo’s age in JJK 0 for SEO

If you are writing a long-form SEO article, you want phrasing that is accurate, readable, and not overly technical. These lines work well:

• “In Jujutsu Kaisen 0 (2017), Gojo is 27 turning 28.”
• “Gojo is 27 for most of 2017, and he becomes 28 after his December 7 birthday.”

That avoids sounding uncertain while still being accurate.

Gojo’s age in the anime, explained without confusion

Many searches for how old is Satoru Gojo are actually anime-driven. People want to know the age of the Gojo they are watching, not necessarily the Gojo they are reading in a specific chapter.

Here is the clean anime logic:

Gojo’s age in Season 1 content

Season 1 is part of the present-day 2018 storyline. That places Gojo at 28.

Gojo’s age in Season 2 content

Season 2 includes two distinct time periods:

• Hidden Inventory / Gojo’s Past is set in 2006, where Gojo is 16 (turning 17 after Dec 7, depending on the month).
• Shibuya-era content is set in 2018, where Gojo is 28 during Shibuya.

So if someone says “Gojo is 16 in Season 2,” they mean the flashback. If they say “Gojo is 28 in Season 2,” they mean Shibuya.

A no-math method to remember Gojo’s age while reading on ComicK

If you want a simple mental shortcut that works even when you are skimming chapters:

If you see student Gojo with Geto in their school days, think 2006, Gojo is 16.
If you see Yuta and the JJK 0 framing, think 2017, Gojo is 27 to 28.
If you see Yuji’s era and modern Tokyo, think 2018, Gojo is 28 until early December, then 29.

This is particularly helpful on ComicK because manga reading often involves quick arc navigation, and your “year awareness” can drop when you read multiple arcs in a single sitting.

Why Gojo feels older than he is

Even though the correct answer is late twenties, many people feel like Gojo “should be” in his thirties or older. That reaction makes sense, and it usually comes from three narrative signals:

Authority position
Gojo is not a side instructor. He is treated as a pillar of the modern sorcerer world. In most series, that role belongs to someone older.

Competence gap
Gojo’s skill level is so far above most characters that viewers subconsciously assume years of experience must be responsible. JJK subverts that by making him a generational anomaly.

Mentor framing
Shonen mentors are often coded as older. Gojo is coded as a mentor, but his behavior and style are coded as youthful. That contrast makes his age feel “wrong” until you see the timeline.

Understanding that he is 28 in the present-day story makes the character design more impressive. He is not a slow-burn master. He is a rare case of someone who reached the top early and then had to decide what to do with that power in a broken system.

Common misconceptions and how to correct them cleanly

When you publish SEO content, you want to anticipate the incorrect variations people search and fix them politely in your copy.

Misconception: Gojo is 30 in the main story

This usually comes from rounding or from confusing post-2018 assumptions. The main story’s present-day core is in 2018, making him 28, and later in 2018 he becomes 29. There is no need to jump to 30 unless you are discussing hypothetical future years.

Misconception: Hidden Inventory Gojo is 18 or 19

This happens when people assume “high school age” and guess. Hidden Inventory is 2006, and Gojo’s birth year is 1989, which puts him at 16 (or 17 after Dec 7).

Misconception: JJK 0 Gojo is the same age as present-day Gojo

JJK 0 is 2017, while the main story is 2018. That is why Gojo is 27 to 28 in JJK 0, then 28 to 29 in the main story depending on the month.

How to phrase Gojo’s age correctly in your own article or social post

If you want copy that is both accurate and natural, these are safe templates:

• “Satoru Gojo is 28 for most of Jujutsu Kaisen’s 2018 timeline, and he turns 29 on December 7, 2018.”
• “Gojo was born on December 7, 1989, which makes him 16 in the 2006 flashback arc and 28 in the main 2018 story.”
• “In JJK 0 (2017), Gojo is 27 turning 28, and in the main series (2018) he is 28 turning 29.”

These lines also naturally include SEO-friendly variants like “Gojo age,” “Satoru Gojo birthday,” and “Gojo age in JJK 0.”

ComicK brand integration that stays useful, not promotional fluff

If your goal is to optimize for ComicK, the best strategy is to integrate ComicK where it improves the reader experience rather than forcing sales language.

Here are natural placements you can use in the article:

• Mention ComicK when talking about jumping between arcs: “If you are reading on ComicK and switching between Hidden Inventory and the present-day chapters…”
• Mention ComicK for clarity around arc order: “On ComicK, following the arc sequence makes Gojo’s age changes much easier to track.”
• Mention ComicK as a consistent reading hub: “Keeping your reading in one place on ComicK reduces timeline whiplash when you revisit earlier arcs.”

This keeps the brand visible while still serving user intent, which is what Google and readers tend to reward.
