【密着】福岡のK-1王者・石井一成　両目網膜剥離でも「戦い続ける理由」　 格闘家の厳しい現実

Kazunari Ishii (27 years old), who runs a Muay Thai gym in Hakata Ward, Fukuoka City, is a fighter who has achieved success as the K-1 Bantamweight Champion. His martial arts career spans 20 years, having followed in his father's footsteps, and he currently coaches many children at his gym, becoming an inspiration to them. While Ishii's career seems to be going smoothly, after his title defense in February of this year, he was diagnosed with retinal detachment in both eyes and underwent surgery. Facing a potentially life-threatening injury for a fighter, he continues to grapple with anxieties about continuing his career. It's difficult for fighters to make a living solely from fight money, and Ishii relies on sponsorship to support his activities. Looking ahead to his second career after retirement, he is considering new ventures such as the food and beverage industry, aiming to protect his beloved gym without turning it into a commercial venture. To pass on the message that "martial arts offers dreams" to the next generation, Ishii is striving to pass the baton to children through his own example. While continuing his injury treatment, he is aiming for the ring for his title defense this summer.
