Para-judo, a sport included in the Paralympic Games since 1988, is specifically adapted for athletes with visual impairments, relying on tactile contact rather than visual cues. Vanessa Casu, a judoka who has recently gained attention on social media for discussing her experience in the sport, highlights the technical modifications—such as the kumi-kata grip—that allow visually impaired competitors to engage in high-level martial arts. According to the International Blind Sports Federation (IBSA), the sport follows the rules of the International Judo Federation (IJF) with key adjustments designed to ensure fair competition for athletes across different classifications of visual impairment.
Understanding the Mechanics of Para-Judo
The fundamental difference between Olympic judo and para-judo lies in how the match begins and how athletes maintain contact. In standard competition, judoka often move freely to find an opening. In para-judo, the competitors start the match with a mandatory grip on their opponent’s gi, known as the kumi-kata. If this grip is broken, the referee stops the action and resets the athletes to the neutral starting position.
This reliance on touch is essential. Because athletes must maintain physical contact, the game becomes a intense test of balance, leverage, and reaction time. According to the IBSA, the sport is divided into two primary classifications: J1 (athletes who are totally blind or have very limited light perception) and J2 (athletes with a higher degree of functional vision). These classifications ensure that athletes compete against others with similar levels of visual acuity.
The Role of Sensory Cues and Auditory Feedback
Beyond the physical grip, auditory cues play a significant role in the environment of a para-judo match. Referees use specific vocal commands and auditory signals to help the athletes understand where they are on the mat. The judo mat, or tatami, is designed with different textures or boundary markers that athletes can feel with their feet to determine their position without needing to see the edge of the competition area.
For athletes like Vanessa Casu, who shares her training and insights on platforms like TikTok, the sport is a testament to the adaptability of human performance. Her content often addresses the common question of how a non-sighted individual navigates the complex throws and pins of judo, emphasizing that the sport is fundamentally about weight distribution and body awareness rather than visual tracking.
International Standards and Paralympic Evolution
Para-judo has undergone significant evolution since its inception at the 1988 Seoul Paralympic Games. Initially, the sport was open only to men, but women’s events were officially introduced at the 2004 Athens Paralympic Games. The International Judo Federation (IJF) works in close coordination with the IBSA to refine rules, ensuring that the sport remains both safe and competitive.
The kumi-kata rules and the classification systems are regularly reviewed to keep pace with modern athletic training. For spectators or those interested in getting involved, the International Blind Sports Federation (IBSA) official website serves as the primary resource for rules, upcoming international tournaments, and classification guidelines. These resources provide the technical framework that allows athletes to compete at the highest levels, regardless of their visual impairment.
How to Follow the Sport
Fans of combat sports can follow the progression of para-judo through the official calendars of the IBSA and the International Paralympic Committee (IPC). With the sport’s profile growing through social media engagement, more athletes are sharing their training regimens and competition experiences, providing a window into the dedication required to master these techniques.

As the sport continues to develop globally, the focus remains on the skill, speed, and strategic depth of the competitors. Whether through official Paralympic broadcasts or the personal accounts of active judoka, the sport demonstrates that visual impairment does not limit the technical complexity or the competitive intensity of judo.
