Kyoji “Karate Kid” Horiguchi is a Japanese professional mixed martial artist known for his karate-based movement, knockout power, and championship success across several major promotions. A former UFC title challenger, RIZIN champion, Bellator champion, and Shooto champion, Horiguchi has built one of the most decorated careers of any Japanese fighter in modern MMA.
Horiguchi owns a professional MMA record of 36-6 with one no contest and has defeated major names including Darrion Caldwell, Kai Asakura, Manel Kape, Sergio Pettis, Ali Bagautinov, Hiromasa Ougikubo, and Ian McCall.

What Is Kyoji Horiguchi Known For?
Horiguchi is best known for five things:
- His karate-based striking style.
- Becoming a UFC Flyweight Championship challenger.
- Winning titles in RIZIN, Bellator, and Shooto.
- Becoming one of Japan’s greatest MMA fighters.
- His speed, footwork, and explosive knockout power.
Unlike many traditional MMA strikers, Horiguchi built his game around movement. He darts in and out of range, attacks from unusual angles, and forces opponents to reset constantly. As a result, he has remained dangerous across several eras of elite competition.
Why Is Kyoji Horiguchi Called “Karate Kid”?
The nickname “Karate Kid” comes from Horiguchi’s martial arts foundation.
He began training karate at just five years old and quickly developed into a talented full-contact competitor. That early training shaped his stance, rhythm, and footwork long before he entered mixed martial arts.
Even after adding wrestling, grappling, and boxing to his game, Horiguchi kept the karate identity that made him unique. Therefore, “Karate Kid” remains one of the most fitting nicknames in MMA.
Kyoji Horiguchi’s Early Life
Horiguchi was born in Takasaki, Gunma, Japan.
He started karate as a young child and soon began competing in full-contact tournaments. However, his interest in MMA grew after watching PRIDE Fighting Championships as a teenager.
At 16, Horiguchi became inspired by Japanese MMA star Norifumi “Kid” Yamamoto. After graduating high school, he joined Yamamoto’s Krazy Bee Gym and began turning his karate background into a complete MMA skill set.
How Did Kyoji Horiguchi Get Into MMA?
Horiguchi made his professional MMA debut in Shooto in 2010.
He quickly stood out because of his speed and knockout power. Soon afterward, he won the Shooto 2010 Rookie Tournament and continued building momentum against tougher opponents.
Although he suffered an early setback against Masakatsu Ueda, Horiguchi rebounded strongly. In 2013, he defeated Hiromasa Ougikubo by rear-naked choke to capture the Shooto Bantamweight Championship.
That win helped establish him as one of Japan’s top young fighters.
Kyoji Horiguchi’s First UFC Run
Horiguchi joined the UFC in 2013 and immediately made an impact.
He won his debut against Dustin Pague by second-round TKO before adding victories over Darrell Montague, Jon delos Reyes, Louis Gaudinot, Chico Camus, Neil Seery, and Ali Bagautinov.
Eventually, he earned a UFC Flyweight Championship opportunity against Demetrious Johnson at UFC 186.
Although Horiguchi lost by late fifth-round armbar, the fight gave him valuable experience against one of the greatest mixed martial artists of all time. Afterward, he continued winning before choosing not to renew his UFC contract in 2017.
Becoming a Star in RIZIN
After leaving the UFC, Horiguchi became one of RIZIN’s biggest stars.
He won the 2017 RIZIN Bantamweight Grand Prix by fighting three times in two days. During that run, he defeated Gabriel Oliveira, Manel Kape, and Shintaro Ishiwatari to become the inaugural RIZIN Bantamweight Champion.
Moreover, he produced one of his most famous highlights in 2018 when he knocked out Ian McCall in just nine seconds.
Horiguchi later added more championship success in RIZIN, proving that he could carry a major promotion while continuing to beat elite opposition.
Bellator Champion and RIZIN Champion
Horiguchi’s résumé grew even stronger when he crossed over into Bellator.
In 2019, he defeated Darrion Caldwell by unanimous decision to win the Bellator Bantamweight World Championship. Since he had already beaten Caldwell in RIZIN, the victory proved that his success translated across promotions.
However, a serious knee injury forced him to vacate the Bellator belt. After a long recovery, Horiguchi returned and defeated Kai Asakura by first-round TKO to reclaim championship momentum.
Later, he moved back to flyweight and captured the inaugural RIZIN Flyweight Championship by submitting Makoto Takahashi.
Kyoji Horiguchi’s Return to the UFC
Horiguchi returned to the UFC after vacating the RIZIN Flyweight Championship.
He made a successful comeback by submitting Tagir Ulanbekov with a rear-naked choke. Then, he defeated Amir Albazi by unanimous decision.
Although he later lost a rematch to Manel Kape, his return still showed that he could compete with elite flyweights after years away from the promotion.
What Is Kyoji Horiguchi’s Fighting Style?
Horiguchi uses a karate-based striking style built around speed, timing, and explosive entries.
He stays light on his feet, controls distance well, and launches sudden attacks before opponents can react. In addition, his wrestling and grappling have improved throughout his career, making him far more than just a striker.
Because of that balance, Horiguchi has won fights by knockout, submission, and decision at the highest level.
What Has Kyoji Horiguchi Accomplished?
Horiguchi has one of the strongest championship résumés in Japanese MMA history.
His accomplishments include:
- Former UFC Flyweight Championship challenger.
- Former Bellator Bantamweight World Champion.
- Former RIZIN Flyweight Champion.
- Two-time RIZIN Bantamweight Champion.
- 2017 RIZIN Bantamweight Grand Prix Champion.
- Former Shooto Bantamweight Champion.
- Shooto 2010 Rookie Tournament winner.
- UFC Performance of the Night winner.
- Victories over champions across multiple promotions.
Why Kyoji Horiguchi Stands Out
Few Japanese fighters have achieved what Kyoji Horiguchi has achieved.
He challenged for UFC gold, became a star in RIZIN, won a Bellator world title, captured belts across multiple divisions, and remained relevant for more than a decade. Moreover, he did it while keeping a distinct karate-based style that made him instantly recognizable.
Because of his longevity, championships, and global success, “Karate Kid” remains one of the most important Japanese MMA fighters of his generation.
