Koyama is credited among the Japanese voice cast of Solo Leveling, though the specific character he plays has not been confirmed in the sources available for this profile. His involvement extends a stage and screen career built at the Haiyuza Theatre Company across nearly four decades. Given his history with commanding, oversized characters, the casting fits a pattern that has defined much of his recent work.
Koyama's early signature roles included Yamato from Naruto Shippuden and Hunter x Hunter's Ging Freecss, plus a long-running turn as the second voice of Kogoro Mouri in Case Closed starting in 2009. He's also carved out a niche playing outsized villains, from Bleach's Coyote Starrk to the towering Deep Sea King in One Punch Man and Fairy Tail's Fukuro. On the dubbing side, he's the go-to Japanese voice for Dwayne Johnson, George Clooney, Kiefer Sutherland, and Ma Dong-seok, and has voiced numerous films starring Denzel Washington, Keanu Reeves, and Guy Pearce.
