In the Cobra Kai world, the famed Sekai Taikai is the ultimate tournament in which every karate fighter wishes to participate and prove themselves. Ralph Macchio's Daniel LaRusso has described the Sekai Taikai Tournament as his "karate swan song," and throughout the six seasons, it has become so.
In the final season, Cobra Kai and Miyagi-Do are all set to perform against other world-class dojos such as the Iron Dragons. Recently, at the Newport Beach TV Fest's panel, made up of the executive producers, who also serve as directors and writers, making up the core team, Josh Heald, Hayden Schlossberg, and Jon Hurwitz. They were joined by Ralph Macchio, Mary Mouser, and Yuji Okumoto. The panel had a lot of interesting discussions, including the origin of the famed Sekai TaiKai tournament. Here's what they revealed.
Cobra Kai panel reveals the origin of the Sekai Taikai tournament

The Sekai Taikai, since its introduction in the fifth season, has grown in the sixth season of Cobra Kai into the most famed karate tournament in the canon. However, in the recent Newport Beach TV Fest panel, Heald, one of the executive producers on the panel, revealed how the showrunners created the Sekai Taikai tournament.
All through the first four Cobra Kai seasons, we as the audience have had some really big fights to look forward to:
"We already had the All Valley in season 1, we had the terrible school fight in season 2, we had an even more terrible house fight, and dojo fight, and fight to the death over a snake pit in season 3… We had another All Valley in season 4, and played around with that, because that was the first time we had boys and girls brackets. So we found a way of not repeating ourselves."
However, the showrunners felt that going into the penultimate season of the show, season 6, they were up against the audience's expectations and needed to come up with something that could exceed all expectations:
"But as we got to season 5, we started saying we can’t just beat the All Valley to death. We’re gonna be going up against audience expectations, and they’re gonna be ahead of us. So we started to introduce the idea of the Sekai Taikai in season 5 as this mythical world tournament that has lived in the shadows. It’s like in Bloodsport. It’s like, "Ooh, people have died there." And you’re just setting the stage for, "You can make a lot of money, or maybe die.""
There was something else that the showrunners and the writers' room had to figure out. They had to come up with a way to make the Sekai Takai completely different than the All Valley fights in Cobra Kai:
"When we eventually arrived at [the Sekai Taikai], we had to discuss amongst ourselves, in the writers room, and with the performers, what is this thing gonna look like? What we didn’t want to have happen was, we’re going to the world tournament, but guess what? It looks exactly like the All Valley, because that would be a letdown. So then it became, what other types of activities and competitions exist in karate tournaments?"
"And then we just stretched that truth a little bit. They’re fighting on a floating platform! They’re getting thrown off onto the hard stage floor. And then tag team tournaments where you can tag in and out. We wanted it to be frenetic. We loved the idea that every year they host the Sekai Taikai, there’s kind of this rotating possibility of events that might get sprung on the competitors so they don’t know what to prepare for, which kind of evens the playing field. And also, occasionally, there’s a new event. So [the Sekai Taikai] became a grab bag of anything we could imagine, within reason…"
"But we knew it would eventually come back to one-on-one [fights], and we’re going to have a champion, and it’s gonna be the language of The Karate Kid and Cobra Kai."
Cobra Kai needed to go really big coming into the final season, and the All Valley Under 18 Karate tournament would not catch up. The Sekai Taikai tournament, set in Barcelona, was exceptionally important, and it managed to give the showrunners a chance to introduce several new aspects, from new opponents skilled in other dojos to a special international taste, ensuring that the sixth and final season could go out with a bang.
The Cobra Kai team ensured that they didn't repeat themselves, and they did it in an exceptional style. Even though the Sekai Taikai tournament was born out of the need to do something different, it has grown into a novelty and a dedicated ode to the art of professional wrestling through its gimmick fights and multi-person format.
