Choo Sung Hoon
Choo Sung Hoon (추성훈), known internationally as Yoshihiro Akiyama and to many fight fans as Sexyama, built a crossover career few athletes manage. Born in Osaka to a Zainichi Korean family, he first made his name as an elite judoka, winning the 2001 Asian Championships, then carried that competitive edge into mixed martial arts, where his charisma turned him into a rare combat-sports figure with mainstream entertainment pull in both Korea and Japan.
That second life on screen is what keeps him culturally relevant now. Choo translated fight-world credibility into broad television recognition through The Return of Superman, then found another global audience through Netflix's Physical: 100. His own YouTube channel pushed that reach even further by showing a version of him that feels less like a legend on loan and more like a naturally entertaining veteran who understands the camera.
In 2026, ENA added him to the master lineup for The Scout: Stars Reborn, a move that made immediate sense. Choo brings discipline, pressure-tested experience, and an energy that cuts through safer mentor casting. That combination is why he still matters in Korean entertainment. He is not a retired athlete making occasional appearances. He is a durable crossover personality with real authority, real humor, and a public image that still carries weight.
