Kento Nanami from Jujutsu Kaisen (JJK) is 28 years old.

This age reflects his status during key events like the Shibuya Incident arc, where he's portrayed as a mature Grade 1 sorcerer with a pragmatic outlook shaped by his corporate past.

Born on July 3, 1990, Nanami would have turned 28 that year amid the series' 2018 timeline, making him a standout adult figure among younger protagonists like Yuji Itadori.

Character Timeline

Nanami's age anchors his backstory:

  • Early 20s : Left Jujutsu High after Gojo's year, tried salaryman life, and returned disillusioned.
  • 27-28 : Active sorcerer, emphasizing "work-life balance" with his 7:3 rule—only fighting curses until 7 PM.
  • By April 2026 (over six years post-manga end), fans still debate if he'd be 34 now in a hypothetical revival.

Why the Age Confusion?

Some sources say 27 at intro, but consensus pins 28 during major arcs.

  • Reddit threads highlight his "mature" look from stress, contrasting teen designs.
  • Playbite and older guides approximate 27, but detailed wikis confirm 28 with birthday math.
