Jujutsu Kaisen Season 3 drops in January 2026, but things have taken a major turn. In addition to Gojo being trapped, Sukuna is going crazy, and the jujutsu world has gone completely insane since the Shibuya Incident. With all of these reincarnated sorcerers from centuries ago being brought into the present day due to the Culling Game, one name is popping up in every conversation: Hajime Kashimo, who is regarded as the God of Lightning and hasn't lost a battle in four centuries.
Yes, Kashimo absolutely appears in Jujutsu Kaisen Season 3: The Culling Game Part 1. He entered the tournament with one mission: to fight Ryomen Sukuna. Kashimo was a warrior in the Edo Period, and he had electrified cursed energy; he eliminated more than 40 players in twelve days, and he could transform using a one-time-use technique, making him one of the most dangerous wildcards during this arc.

Kashimo is one of the coolest additions to Jujutsu Kaisen Season 3. He was a fighting dude back in the Edo period (about 400 years ago) and made a name for himself as the baddest fighter (even Kenjaku took notice of his skills).
Kashimo is driven by a singular, all-consuming desire: to find combat that is worthy of him. While many sorcerers are motivated by vengeance or ideology, Kashimo's only motivation is the battle, as he wants to experience what his true limits are against an opponent that can force him to exceed those limits.
Mythical Beast Amber: The Ultimate Gamble in Jujutsu Kaisen Season 3
Kashimo has a unique cursed technique that really is his last resort. When activated, his mythical beast technique, "Amber," allows him to recreate his body and grants him immense electrical powers. When Kashimo activates this technique, he becomes lightning itself.
With this transformation in Jujutsu Kaisen Season 3, he can now control electromagnetic waves, have increased speed, and make sound-based attacks. At the same time, he'll be so physically advanced that no other top-tier sorcerers will be able to compete with him.
But this power has a severe price. Kashimo has to activate his power, Mythical Beast Amber, which only occurs once, before he goes into the process of his body breaking down due to all the excess stress caused while exceeding his natural limitations, which means he’s putting everything he has into a single final blow with explosive force.
Role in the Jujutsu Kaisen Season 3 Culling Game Part 1

Kashimo totally owns his colony in the Jujustu Kaisen Season 3 Culling Game right from the beginning, and he takes people out super fast. He even created a new rule so that everyone can see some basic info about other players.
It's only a matter of time before he has to fight against the other big guys in the game. There are some really intense fights in the manga, and Kashimo and his opponents are pushed to their limits. The battle between Kashimo and Kinji Hakari is one of the biggest fights in this arc.
While he may have seemed like a bad guy at the beginning, Kashimo's objectives don't fit into Kenjaku's overall schemes for the ritual. As he progresses, his only goal is to beat Sukuna, and this goal becomes bigger than everything else in his life. So, rather than being just another villain, he turns out to be somewhat unpredictable.
Why Kashimo Matters in Jujutsu Kaisen Season 3

The 400-year-old warrior is not just a beast; he redefines what jujutsu sorcery means by teaching techniques and philosophies developed in a time no longer relevant to modern-day sorcerers and pushing everyone else to adapt when he arrives. Even though his story has many elements of tragedy, he becomes interesting because of the tragedy surrounding him.
His desire to have meaningful combat stems from hundreds of years of being unfulfilled by all of the fighters he fought with in his original time and still not being able to fill that void, even with all the fame and respect he gets by being a "legend".
Everyone's buzzing about the return of Hajime Kashimo in Jujutsu Kaisen Season 3: Culling Game Part 1. The dude's an absolute beast with years of fight training under his belt, plus he can zap you with some crazy electrical powers. He's obsessed with chopping heads, so expect a whole lot of challenges in this thing called The Culling Game.
