Teppei Kisugi, recognized internationally as Johnny Mason, emerges as a determined Japanese forward and classmate of Genzo Wakabayashi at Shutetsu Institute. Beginning in Shutetsu’s lower-tier squad, he hones his skills through intense training sessions at Wakabayashi’s mansion, ascending to the main team. His pivotal moment arrives in the Prefecture finals against Shimizu FC, where his decisive goal against goalkeeper Morimichi Kawakami clinches Shutetsu’s triumph in the 5th Yomiuriland National Junior Tournament alongside Wakabayashi, Izawa, Taki, and Takasugi. As part of the Shutetsu Trio with Mamoru Izawa and Hajime Taki, Kisugi masters rapid combination plays, particularly the Shutetsu Trio One-Two—a seamless technique refined since elementary school. This synergy dismantles defenses with precision. His collaboration with Taki evolves into the Nankatsu Silver Combi during their Nankatsu Middle School years, renowned for dynamic, high-speed attacks. Transferring to Nankatsu’s middle and high school teams solidifies his role as a leading striker, though national team opportunities dwindle amid fierce competition from forwards Kojiro Hyuga and Shun Nitta. Kisugi’s professional career launches with Cerezo Osaka in the J1 League, followed by a place on Japan’s U-23 Olympic squad. Despite limited playtime—highlighted by a brief appearance in a preparatory match against Denmark—his sharp opportunistic instincts and tactical acumen secure recurring call-ups across national youth teams. Technically adept, Kisugi employs the Sliding Shot, a low-driven strike executed mid-sprint, alongside collaborative strategies like the Shutetsu Trio One-Two. These tools define his supportive yet impactful style, prioritizing teamwork over solo brilliance. His 172 cm, 64 kg frame complements an agile, positionally astute approach. Central to his narrative is a longstanding camaraderie with Taki, rooted in elementary school. This bond fuels their on-field chemistry and personal resilience, shaping Kisugi’s journey of perseverance as he adapts to shifting team hierarchies and contends with elite rivals, embodying tenacity in pursuit of growth.
