Early Career
From a scrawny 14-year-old who could barely crank out three push-ups, Takayama’s early days were all about determination. His friend first introduced him to a local boxing gym, and he immediately vowed to become a world champion.
Despite initial struggles on the bag and in sparring, his work ethic saw him win the All-Japan Rookie King Tournament in December 2001. He built an unblemished record over his first ten fights, defeating opponents by decision and knockout across schools and local promotions.
By age 21, he had already earned a shot at the WBC mini-flyweight title, marking the start of a career defined by international travels—from South Africa to Mexico—in pursuit of world crowns. His combination of rapid footwork, straight punches and unshakeable resolve set him apart as a rising star long before he first hoisted a green and gold belt.
Professional Career
Takayama’s pro career has spanned more than 20 years and five gyms, making him one of the most well-traveled Japanese world champions. In April 2005 he won the WBC mini-flyweight title by unanimous decision over Isaac Bustos, becoming only the 50th Japanese fighter to claim a world boxing crown.
After losing that belt later that year, he spent the next decade capturing the WBA interim, IBF and WBO titles, often fighting on enemy soil. Notable highlights include dethroning Mario Rodríguez in Mexico in 2013 for the IBF title and unifying vacant belts against Go Odaira in Osaka in 2014.
He retired in 2017 as the reigning WBO mini-flyweight champ to pursue an Olympic dream, then returned to pro boxing in late 2020. His comeback has featured victories over Reiya Konishi, Jerome Baloro and most recently Kha Lu for the IBO belt.
Across four organizations, he has proven time and again that age is just a number, delivering action-packed performances well into his 40s.
