Cursed techniques can often be seen as the reason some of the strongest characters exist at the highest levels of power in the Jujutsu Kaisen. Especially for these characters, their techniques were so powerful that they were instantly shot to higher levels of power in the environment.
However, powerful techniques do not automatically bring someone to the level of disasters like Sukuna or Gojo Jujutsu Kaisenalthough they definitely help. In this article, we will look at many eras of the series to determine which cursed technique was the most powerful in the setting at that time.

Brain transplantation was the most powerful technique before the Heian era
User: Kenjaku
To this day, Kenjaku remains one of the most elusive characters in the entire franchise, mainly because we know next to nothing about where he came from. However, due to Tengen's knowledge of him and how he managed to make a pact with Dhruv centuries before the Heian era during the Wa Civil War in the Yayoi period, Kenjaku is confirmed to be an ancient.
He may be the oldest character of them all and the reason he was still alive at the end of the original series was his Brain Transplantation technique. Although not powerful from an offensive standpoint, it allows Kenjaku to bounce from body to body, effectively making him immortal while allowing him to take on the cursed technique of the person he is inside.

The shrine was the most powerful technique of the Heian era
User: Ryomen Sukuna
As the strongest wizard in history, one would think that Sukun's technique was also the best of them all. While the Shrine is undeniably powerful, it was far from the strongest technique in the series and only really shined through Sukuna's use of it and mastery of jujutsu as a whole. Still, it was definitely the strongest technique of the Heian era.
Known as the Golden Age of Sorcery, many powerful beings and techniques were present at this time, but Sukun's legendary technique had such immense offensive power that he was able to effortlessly defeat anyone he came up against. In modern times, Sukun's use of the shrine also cemented her as one of the greatest techniques ever.

Ten Shadows was the most powerful technique 400 years ago
User: Unknown Zenin Clan Head
In the final showdown where Gojo fought against Sukuna, the Ten Shadows arguably proved to be the most powerful technique in the entire series through its crown jewel, the Mahoraga. It was due to Mahoraga's impaired adaptability that Sukuna was able to learn World Cutting Slash to bypass Gojo's Infinity.
However, Ten Shadows was definitely the most powerful technique in a setting 400 years before the start of the original series. Gojo explains that at this time, the head of the Gojo clan, who had access to Six Eyes and Limitless like him, was fighting against the head of the Zenin clan, who had ten shadows. The resulting battle saw the deaths of both, showing that Mahoraga has long been the answer to the Infinite.

The mythical beast Amber was the most powerful technique of the Edo period
User: Hajime Kashimo
Although much condemned and criticized for his performance against Sukuna, Kashimo was still one of the few people to ever hold the title of strongest in his era. His power was so legendary that he was able to kill anyone he went up against in the Edo Period just through his physicality and cursed energy manipulation.
With the Mythical Beast Amber, Kashim's strength and speed have increased to incredible levels as he can move at blinding speeds and use the air itself to launch powerful Cursed Energy projectiles. Although it is a one-time ability, Mythical Beast Amber allows Kashimo to become one of the strongest characters in the series.

Limitless was the most powerful technique of the modern era
User: Satoru Gojo
Despite being the first human in 400 years to be born together with the Limitless Six Eyes, Gojo truly owed his status as the strongest of the modern era to himself and his own hard work. Limitless is undoubtedly the most powerful technique when used with the Six Eyes, but Gojo has proven that he is definitely the strongest person to ever call these powers his own.
The main reason is that the only other mentioned user of Six Eyes and Limitless was killed by Mahoraga 400 years ago. However, Gojo not only defeated an even stronger version of the Divine General, but also took on the Curse King and Agito, proving that he was the strongest because he was Satoru Gojo and not the other way around, as Geto had wondered all those years ago.

(…) And light is the most powerful technique of the Modulo era
User: Dabura Karaba
Although some fans would argue that Yuji's technique is the strongest since he himself exists on a level even beyond Gojo and Sukuna, the truth is that Dabur's technique allows him to manipulate light as he sees fit, which can be through powerful projectiles or even on himself, allowing him to move faster than anyone else in the franchise.
The latter power makes Dabury the fastest character of all Jujutsu Kaisen by a mile, showing his technique to be one of the strongest in series history. Although Modulo Era Yuji would probably beat him in a fight, Dabur's insane power is definitely the greatest in the entire future setting of the game. Jujutsu Kaisen.
