Satoru Kitaoka: A Master of the MMA Arena

Satoru Kitaoka is a Japanese lightweight mixed martial artist and grappler whose career has stretched across more than two decades of competition. A longtime fixture of Pancrase and other Japanese promotions, he became known for pursuing submissions and using a persistent ground game against both domestic rivals and international names. His path includes championship success in Sengoku and DEEP, as well as a later run in RIZIN.

A grappler shaped by Pancrase

Kitaoka was born in Nara on February 4, 1980. Pancrase’s fighter profile lists judo and Brazilian jiu-jitsu as his background and records his promotional debut in October 2000. He developed into a submission specialist, with victories by guillotine, heel hook, and other grappling finishes. His approach could make bouts difficult to watch for fans seeking constant striking, but it gave him a clear identity and a durable route to success against experienced opponents. The Pancrase profile documents his early career and training background.

Sengoku and DEEP championships

A major breakthrough came in 2008, when Kitaoka won the Sengoku lightweight Grand Prix. In January 2009, he defeated former PRIDE champion Takanori Gomi to become the inaugural Sengoku lightweight champion. MMA Fighting’s event report covers the title result. Kitaoka later won the DEEP lightweight championship and defended it, including a 2014 decision over Naoto Miyazaki. These accomplishments established him as one of Japan’s leading lightweight grapplers.

His career also included difficult periods. Kitaoka was stopped by Ramazan Esenbaev at the 2013 Inoki Bom-Ba-Ye event, then returned to win and defend the DEEP belt. He continued to compete in RIZIN and DEEP into his forties, making his longevity itself part of his story.

Still competing

Kitaoka has not retired. As of September 2026, his record stood at 45 wins, 30 losses, and 10 draws. His most recent bout was a unanimous-decision loss to Yajuro Yamasaki at DEEP 133 Impact on September 13, 2026. The updated Sherdog record lists the result and career totals. His long career reflects the persistence of a specialist who continued to test himself across promotions, generations, and changing eras of Japanese MMA.
