DJB Kata Event 2026: How Germany’s Elite Judo Athletes Refined Their Craft in Cologne

By Daniel Richardson, Editor-in-Chief

COLOGNE, Germany — For three days in late April, the German Judo Federation (DJB) transformed its national training center into a laboratory of precision, tradition, and innovation. The DJB Kata Event 2026, held from April 24–26 at the Bundesleistungszentrum Köln, drew athletes, coaches, and kata enthusiasts from across Germany and beyond for a weekend of intensive training, technical refinement, and cross-disciplinary exchange. Among the participants were two rising stars from northern Germany: Kajsa Kuballa and Tjorge Daberkow, members of the Judo-Verband Schleswig-Holstein e.V. (JVSH), who used the event to sharpen their skills ahead of a packed competitive calendar.

What Is Kata — And Why Does It Matter in Modern Judo?

For those unfamiliar with the term, kata (型 or 形) refers to pre-arranged forms in judo that demonstrate fundamental principles of the sport. Unlike randori (free sparring), kata emphasizes precision, control, and the philosophical underpinnings of judo, such as balance, leverage, and mutual respect. While often associated with belt examinations and traditional practice, kata remains a vital tool for high-performance athletes seeking to refine technique, deepen understanding of movement mechanics, and maintain a connection to judo’s roots.

The DJB Kata Event 2026 was designed to bridge the gap between tradition, and innovation. According to the official program, the weekend offered a mix of classical kata forms — including Nage no Kata (forms of throwing), Itsutsu no Kata (five forms of natural energy), and Katame no Kata (forms of grappling) — alongside modern adaptations like Ralf Lippmann’s Modan’na Nage no Kata, which integrates contemporary competitive techniques with classical elements. This hybrid approach reflects a growing trend in elite judo: using kata not just for formal testing, but as a dynamic training tool to enhance randori performance.

The Weekend in Cologne: A Timeline of Intensity and Insight

Kuballa and Daberkow arrived in Cologne on the afternoon of Friday, April 24, joining athletes from across Germany for a weekend that blended structured workshops, free training, and peer exchange. Here’s how the event unfolded, based on verified reports from the JVSH and DJB:

Friday: Foundations and First Feedback

The weekend began with an open training session, allowing participants to acclimate and receive initial feedback from coaches. Kuballa and Daberkow worked with Jochen Müller, a respected figure in German judo, before shifting focus to the evening’s main event: a workshop on Itsutsu no Kata, led by Dirk De Maerteleire, a Belgian judo expert and frequent collaborator with the DJB. The session explored the kata’s five movements, each representing natural forces — a conceptual framework that resonated with the athletes as they prepared for upcoming competitions.

Saturday: A Deep Dive into Nage no Kata

The second day was the most intensive, with Kuballa and Daberkow dedicating nearly 12 hours to Nage no Kata, their primary competitive discipline. The day began with Taiso, a dynamic warm-up routine led by Jenny Frey, designed to enhance mobility, coordination, and body awareness. From there, the athletes immersed themselves in the 15 throws that comprise Nage no Kata, working in pairs to perfect timing, posture, and execution.

What set this session apart was the real-time feedback loop. De Maerteleire, along with other high-level coaches, provided individualized critiques, while peer exchanges allowed athletes to compare interpretations and troubleshoot common challenges. “The opportunity to train alongside athletes from different regions and receive direct feedback from experts like Dirk was invaluable,” Kuballa later reflected in a JVSH report. “We left with concrete adjustments to implement in our next training cycle.”

Sunday: Innovation and Reflection

The final day offered a lighter, more exploratory tone. Participants sampled various kata forms, including a presentation of Lippmann’s Modan’na Nage no Kata, which reimagines classical throws through the lens of modern competitive judo. The weekend concluded with a group discussion, allowing athletes to share takeaways and network with peers and coaches.

Who Attended — And Why It Matters

The DJB Kata Event 2026 was not limited to elite competitors. According to the DJB’s official announcement, the event was open to “all kata-interested individuals,” from beginners to advanced practitioners, including:

• Youth athletes (via the “Kata Fun for Kids” and “Jugend Kata-Quest” programs),
• Trainers and coaches seeking to expand their pedagogical toolkit,
• Dan candidates preparing for belt examinations (the event included modular testing for ranks up to 5th Dan), and
• International participants, reflecting the DJB’s role as a hub for European judo development.

The inclusive structure underscores a broader shift in judo’s approach to kata. Once viewed as a niche or ceremonial practice, kata is increasingly recognized as a performance enhancer. For athletes like Kuballa and Daberkow, the weekend was less about tradition for tradition’s sake and more about gaining a competitive edge. “The details we worked on — grip adjustments, footwork timing, the transition between throws — are directly applicable to randori and competition,” Daberkow noted in a post-event interview with JVSH.

What’s Next for Kuballa and Daberkow?

The timing of the DJB Kata Event 2026 was strategic for the Schleswig-Holstein duo. Just one week after the Cologne workshops, they made their international debut at the Kata World Series in Louvain-la-Neuve, Belgium — a significant milestone in their careers. The event, held on May 2, marked their first exposure to the global kata circuit, where precision and presentation are judged as rigorously as technical execution.

“The feedback and refinements from Cologne gave us confidence heading into Belgium,” Kuballa said. “We were able to focus on the mental aspects of competition, knowing our technique was solid.” While results from the Kata World Series have not yet been published by the International Judo Federation (IJF), the experience is expected to inform their preparation for Germany’s domestic competitions, including the upcoming Landeseinzelmeisterschaften der U11 und U13 in Itzehoe on May 30–31.

The Bigger Picture: Kata’s Role in Modern Judo

The DJB Kata Event 2026 is part of a larger resurgence of kata in competitive judo. While randori remains the cornerstone of high-performance training, kata is experiencing a renaissance as athletes and coaches rediscover its utility. Key factors driving this trend include:

1. Technical Precision: Kata forces athletes to leisurely down and dissect movements, revealing inefficiencies that may go unnoticed in fast-paced randori.
2. Injury Prevention: The controlled nature of kata allows for high-repetition training with minimal risk of injury, making it ideal for recovery periods or off-season conditioning.
3. Mental Conditioning: The focus required for kata — memorizing sequences, synchronizing with a partner, and maintaining composure — translates to improved concentration in competition.
4. Cultural Preservation: As judo continues to evolve, kata serves as a link to the sport’s philosophical and historical foundations, ensuring that core principles are not lost amid the pursuit of medals.

The DJB’s investment in events like this reflects a broader strategy to integrate kata into the athlete development pipeline. By offering workshops that cater to all levels, the federation is not only preserving tradition but also equipping the next generation of judoka with tools to excel in both kata and randori.
