Naoyuki Kotani: A Retrospective on the MMA Veteran

Naoyuki Kotani is a Japanese lightweight whose professional career began in 2000 and has stretched across several generations of the sport. A submission-oriented fighter, he competed in Japan and abroad, including appearances in RINGS, ZST, Shooto and the UFC.

A long career across promotions

Kotani made his professional debut in September 2000. His record includes bouts in Japan as well as overseas, and his résumé features encounters with established lightweights such as Yves Edwards, Marcus Aurélio, Rich Clementi and Koji Oishi. Across a lengthy career, he became known for pursuing submissions: Sherdog’s record lists 27 of his wins by submission.

Kotani made his UFC debut against Thiago Tavares at UFC Fight Night 9 in April 2007, losing a unanimous decision. Dennis Siver then stopped him with punches in the second round at UFC 75 in September 2007. After several years competing outside the promotion, he returned in 2014. He lost to Norman Parke by second-round TKO and to Yan Cabral by rear-naked choke, then lost a unanimous decision to Kajan Johnson at UFC Fight Night in Japan in September 2015. The UFC run was a small part of a much longer career across Japanese and international MMA promotions.

Kotani continued competing after his UFC appearances. He lost to Youta Hayashi at Grachan 65 in October 2023, then returned the following year. Sherdog records a December 2024 loss to Shunsuke Kusawake at Grachan Presents: Helios. As of that bout, the listed professional record was 37 wins, 20 losses and 7 draws; records can vary by database because some sources classify bouts differently.

Kotani’s career is notable for its longevity and the range of opponents and promotions it spans. His results include many submission victories, while his continued appearances late in his career show an athlete who remained active long after his initial UFC opportunity.
