About Our Founder

My name is Kohsuke Ikeda. I was a member of the Japanese team at the Tokyo Olympic Games in the men’s 4×400m relay.
Unlike many athletes, I did not have the opportunity to train under regular coaches. As a student at the Faculty of Medicine at Tottori University, it was not an environment where I could fully dedicate myself to an athletic career. As a result, I often trained alone.
Fortunately, however, I was surrounded by passionate and supportive teammates who constantly encouraged and motivated me.
Top athletes cannot achieve their dreams alone. Their success is made possible by many factors—coaches, teammates, families, fans, training facilities, and sometimes even luck.
Because of this, I believe athletes have a responsibility to give back to the people and communities that support them. I call this idea Athlete Social Responsibility (ASR).
Voice&Sport is an organization that supports and encourages athletes to create positive social impact. We believe in the power of sport, not only to inspire people, but also to address and raise awareness of important social issues.
My Career
2025 -
Founder of Voice&Sport
After retiring from competition, I founded Voice&Sport, where I work to promote Athlete Social Responsibility (ASR) and raise awareness of social issues through sport.
2020 - 2024
Professional Athlete
(Track & Field, sprinter, 400m)
While working as a medical doctor, I was selected as a member of the Japanese national team for the Tokyo Olympic Games. At the 2021 World Relays, I also set a Japanese national record in the mixed 4×400m relay.
2014 - 2020
Tottori University
Faculty of Medicine
Until high school, I specialized in long-distance running, but I switched to the 400 meters after entering university. At Tottori University, a regional university without a strong track and field tradition, I had to adapt to 400m training for the first time. Despite the challenges, I experimented with different training methods and steadily improved my performance. After switching events, my times improved dramatically, eventually leading to a runner-up finish at the Ibaraki National Sports Festival.
