Exploring the Roots of Groundwork: Kosen Judo and Its Influence on Jiu Jitsu

When we trace the lineage of Brazilian Jiu Jitsu, one of the most fascinating branches we encounter is Kosen Judo—a specialized style of judo that emphasizes groundwork (newaza). At El Dorado Hills Jiu Jitsu, we strive to honor the traditions that have shaped the art we practice today, and Kosen Judo holds a unique place in that history.

What is Kosen Judo?

Kosen Judo originated in Japan in the early 20th century, gaining popularity in high schools and universities. While traditional judo, developed by Jigoro Kano, emphasizes a balance between throwing techniques (nage waza) and groundwork, Kosen Judo became renowned for its focus on grappling on the mat.

The name “Kosen” refers to higher education institutions, as it was primarily practiced in academic settings. Competitions often featured prolonged exchanges in newaza, allowing practitioners to develop intricate submissions, escapes, and positional control.

Kosen Judo’s Role in the Evolution of Jiu Jitsu

Kosen Judo significantly influenced the development of Brazilian Jiu Jitsu. Mitsuyo Maeda, a judoka trained in both traditional and Kosen-style techniques, brought his skills to Brazil in the early 1900s. Maeda’s teachings, combined with the innovations of the Gracie family, evolved into what we now recognize as Brazilian Jiu Jitsu.

One of the key contributions of Kosen Judo to modern Jiu Jitsu is its focus on positional hierarchy and submissions. Techniques like guard passing, sweeps, and transitions from guard to dominant positions stem from Kosen principles. These foundational concepts are still core to the curriculum we teach at El Dorado Hills Jiu Jitsu.

Why Kosen Judo Matters Today

In an age where combat sports often emphasize athleticism and explosive techniques, Kosen Judo reminds us of the art of patient, methodical grappling. By studying the principles of Kosen Judo, practitioners can deepen their understanding of leverage, timing, and strategy on the mat.

For students at El Dorado Hills Jiu Jitsu, exploring Kosen Judo serves as a bridge between tradition and modernity. It connects us to the historical roots of groundwork while reinforcing the techniques and strategies we use every day.

Bringing Kosen Principles to Your Training

If you’re interested in incorporating Kosen Judo-inspired techniques into your Jiu Jitsu journey, consider focusing on the following:

• Guard Retention and Sweeps: Kosen practitioners excelled in using guard to control and reverse opponents. Dedicate time to perfecting your sweeps and escapes.

Kosen Judo and Brazilian Jiu Jitsu: Exploring the Grappling Connection

At El Dorado Hills Jiu Jitsu, we are deeply connected to the history and evolution of grappling arts. One of the most fascinating influences on Brazilian Jiu Jitsu (BJJ) is Kosen Judo, a specialized form of judo with a strong emphasis on ground fighting, or ne-waza. Understanding the connection between these two arts can enrich our approach to BJJ and shed light on how the grappling world evolved.

What is Kosen Judo?

Kosen Judo originated in Japan in the early 20th century as a subset of traditional judo. While judo, founded by Jigoro Kano, is known for its dynamic throws and stand-up grappling (tachi-waza), Kosen Judo placed much greater emphasis on ground techniques, including pins, joint locks, and strangles. The style developed largely within Japan’s university system, where teams competed under special rules that favored longer periods of groundwork, unlike traditional judo competitions.

Kosen Judo quickly became known for its sophisticated and technical approach to controlling opponents on the ground—a trait that heavily influenced the development of BJJ.

The Evolution of BJJ from Judo

Brazilian Jiu Jitsu owes much of its foundation to judo, and especially to Kosen-style ne-waza. When Mitsuyo Maeda, a Kodokan judoka, arrived in Brazil in the early 20th century, he passed on his grappling knowledge to the Gracie family and others. Maeda’s teachings included many of the ground-fighting techniques that had been refined in Kosen Judo, which eventually evolved into the distinct style we know as BJJ today.

While early judo retained a focus on both throws and groundwork, BJJ took the groundwork aspect to a new level. Practitioners honed their skills in controlling, submitting, and neutralizing opponents on the mat, developing a vast array of sweeps, guards, and submissions.

Key Similarities Between Kosen Judo and BJJ

  1. Emphasis on Groundwork: Both arts prioritize the ability to control an opponent on the ground. While Kosen Judo does incorporate throwing techniques, the majority of the strategy revolves around transitioning to the mat and gaining a dominant position.
  2. Submissions: Just like in BJJ, Kosen Judo includes various joint locks and chokes. The key difference is that BJJ refined these techniques further, allowing for even more diverse and fluid submissions from various positions.
  3. Guard Play: Kosen Judo’s influence can be seen in the way BJJ developed guard positions. Guard, in BJJ, is a key part of defense and attack, where a practitioner can control or submit an opponent from their back. Kosen Judo already contained the seeds of this idea, though it was in BJJ where it truly flourished.
  4. Competitive Focus: In modern judo competitions, groundwork is often limited due to rule changes that favor stand-up techniques. However, Kosen Judo, with its university competition rules, allowed for a much greater focus on groundwork, similar to how BJJ competitions play out today.

Why Understanding Kosen Judo Matters for BJJ Practitioners

As BJJ continues to evolve, understanding its roots in Kosen Judo can provide a deeper appreciation for the techniques we practice daily. By studying the methods of Kosen Judo, we can refine our own ground game, gaining insights into leverage, control, and the finer details of ne-waza.

In fact, some techniques used in BJJ today, such as certain sweeps, transitions, and escapes, can be traced back to the strategic groundwork of Kosen Judo. Recognizing this historical lineage helps us to approach BJJ not just as a modern martial art, but as part of a larger grappling tradition.
