Shohei Ono, the two-time Olympic judo champion, attributes his sustained dominance on the tatami to a disciplined, introspective approach he describes as “defensive pessimism.” Rather than relying on innate talent alone, the retired judoka spent his career obsessively identifying his own vulnerabilities to prevent potential defeats, a mindset that underpinned his gold medal runs at the 2016 Rio de Janeiro and 2021 Tokyo Olympic Games.

The Philosophy of Defensive Pessimism

Ono, who retired as one of the most decorated judoka in history, maintains that his strength was a direct result of acknowledging his own weaknesses. According to his former coach Yusuke Kaname, Ono adopted a strategy of “defensive pessimism,” a psychological framework where he assumed he was vulnerable and therefore required more rigorous training than any of his peers. This approach fueled his preparation for the Tokyo Games; whenever observers praised his strength or his intense practice schedule, Ono would internally challenge himself, asking, “Am I really that strong?” or “Is this level of training truly enough?”

This persistent self-questioning served as a safeguard against complacency. Ono noted that he spent his daily life analyzing exactly how he could be defeated. He viewed any possibility of loss, however small, as an unacceptable risk. By assuming the worst-case scenario, he was able to implement the necessary care and technical coverage to mitigate those risks, transforming potential negatives into a structured, proactive training regimen.

Historical Influences on Judo Strategy

Beyond modern sports psychology, Ono’s approach was informed by classical Japanese literature and philosophy. During his graduate studies, he turned to Miyamoto Musashi’s 17th-century treatise, The Book of Five Rings, to better understand the relationship between vulnerability and martial efficacy. He also cited the manga Vagabond, which fictionalizes Musashi’s life, as a significant influence. His mentor, Haruya Mochida, reinforced this perspective, often telling Ono, “You are strong because you know your own weaknesses.”

Transitioning from Athlete to Mentor

Ono’s relationship with the sport has shifted since he transitioned into a coaching and mentorship role at the Asahi Kasei Judo Club. While his career was defined by his ability to execute throws on the world stage, he now finds himself on the receiving end of those same techniques during practice sessions. He reflects on this evolution with a sense of irony, noting that while the meaning of being thrown has changed from his competitive days, there is a certain balance to his life now that he is no longer the one exclusively doing the throwing.

Reflecting on his development from a student at the renowned Kodogakusha judo school to a global champion, Ono emphasizes that no athlete begins their journey as a finished product. He points to legends like Yasuhiro Yamashita as rare exceptions to the rule, noting that for most, the growth process is inherently tied to the experience of losing. For the current generation of teenage athletes, his message remains rooted in this foundational truth: true strength is not the absence of weakness, but the active, daily process of identifying and addressing it.
