What is Judo: Principles, Techniques and Belt Rankings

Judo is a Japanese martial art and combat sport founded in 1882 by educator Jigoro Kano, built on the principle of using an opponent's momentum rather than opposing brute strength. Translating to the “gentle way,” the discipline relies on throwing, holding, joint-locking, and choking techniques while entirely eliminating strikes, kicks, and weapons.

The Core Principles and Techniques of the Sport

The foundation of judo rests on efficiency and timing. Practitioners, known as judoka, win by unbalancing opponents through calculated yielding rather than direct resistance. Because the sport prohibits punches, kicks, and weaponry entirely, physical safety during high-impact contact relies heavily on the proper execution of breakfalls, known as ukemi, which are taught on traditional straw mats called tatami.

Competitors wear a reinforced cotton jacket and trousers called a judogi, designed to withstand intense gripping and pulling during bouts. Matches and training sessions take place barefoot on the mat surface. The historical evolution of the sport traces back to jujutsu. Kano removed the striking and kicking elements of traditional jujutsu to create a rigorous combat sport where practitioners could apply maximum physical effort during sparring without sustaining severe injuries.

Ranking Systems and Belt Colors in Ludwigsfelde

Progression through the ranks is marked by specific belt colors that denote technical mastery rather than raw combat strength. Nine student grades, known as Kyu-grade, run from white up to brown before reaching the black belt master levels, or Dan-grades. The initial rank of 1st Dan is viewed within the sport as the starting point for serious study rather than a final destination. V. maintains a structured grading syllabus that extends up to the 6th Dan, incorporating both technical examinations and contributions to club leadership, coaching, and refereeing.

The grading hierarchy progresses through distinct color tiers:

  • 9th Kyu: White
  • 8th Kyu: White-Yellow
  • 7th Kyu: Yellow
  • 6th Kyu: Yellow-Orange
  • 5th Kyu: Orange
  • 4th Kyu: Orange-Green
  • 3rd Kyu: Green
  • 2nd Kyu: Blue
  • 1st Kyu: Brown
  • 1st to 5th Dan: Black
  • 6th to 8th Dan: Red-White
  • 9th and 10th Dan: Red

Training Schedules and Getting Started on the Mat

Beyond physical combat techniques, the philosophy established by Kano places heavy emphasis on mutual welfare and benefit. Training sessions always begin and end with a bow, placing legal and moral responsibility on the person executing a throw to ensure their partner lands safely. Core values taught alongside physical drills include courtesy, respect, courage, modesty, and self-control.

Introductory trial training is available free of charge without requiring prior registration or a specialized judogi, allowing prospective members to experience tatami workouts directly during scheduled club hours.
