The gentle way

Judo turns an opponent's force into their own downfall. No strikes, no weapons — only balance, timing and the willingness to be thrown a thousand times before you throw.

Three pillars

Nage-waza

Throwing techniques. Break the balance, fit in, execute — kuzushi, tsukuri, kake.

Katame-waza

Grappling on the ground: holds, strangles and armlocks that end a contest without a strike.

Ukemi

The art of falling. The first thing every beginner learns, and the reason judo is safe to practise hard.

The belt

White to black is a beginning

Kano invented the coloured belt system so progress could be seen at a glance. Shodan — first-degree black belt — does not mean mastery. It means you have learned enough to start learning properly.

  • 6th kyu — white
  • 5th–4th kyu — yellow / orange
  • 3rd–1st kyu — green, blue, brown
  • 1st dan and above — black
“Softness controls hardness.”
