Anton Geesink set the judo world on fire by defeating Koji Sone in the 1961 World Championships. The tall and imposing Dutchman was the first non-Japanese judoka to win in any weight-class in a world championship.

However, Geesink wasn’t satisfied with the way he won. He wrote in his book, My Championship Judo, that he used a “halfway trick” to put Sone to the ground before immobolising him for victory. He felt that despite being the world champion, he needed to continue to improve.

When Geesink visited Japan in 1963 at the invitation of Tenri University, which had some of the best judoka in the world, he learned that Ne-Waza, or ground technique, was the Judo of the future. “In fact, it was the finals of the open weight class competition at the 1964 Tokyo Olympics when Geesink took advantage of a failed Tai-Otoshi attempt by his opponent, Akio Kaminaga. Geesink instead ended up pushing the Japanese to the mat, immediately maneuvering for a Ne-Waza technique Geesink no doubt sharpened at Tenri University.

 

Geesink wrote in his book that in his time (the 1960s), Ne-Waza, or ground technique, was considered minor by many Japanese judoka purists. “They are – in my opinion – too romantic with their insistence on deciding the contest by a spectacular throw.” But he learned in Japan that for training to be successful, 60% of the time needed to be spent on Ne-Waza, and the remaining 40% on Tachi-Waza.

Here is how Geesink explains a particular Ne-Waza technique – the Kesa-Gatame:

My opponent is recumbent on his back. I am at his right side, my right leg stretched forward, resting on the outside of the foot. My left leg is bent, so that I sit in what one might call a hurdling posture (think of hurdle-racing). My right arm passes around his head, so that I can hold his upper-arm with my right hand. With my left arm I lock in his right arm, which is gripped around my body. My armpit presses against his wrist and with my left hand I grip him precisely under his elbow. Consequently my opponent’s right arm forms a right angle; his elbow sticks out.

By concentrating my full weight on his trunk, resting only on the outside of my right foot and on the sole of my left foot, so that my buttocks have no contact with the ground, it has become impossible for him to move. If my opponent should succeed in resting the back of his head on the ground, he might be able to develop enough strength to free himself from my immobolising hold. To prevent this, I draw my right arm so tight that his head is moved forward, away from the ground. He has now become quite helpless, immobolised.

And when that actually happened in the finals of the open weight class at the 1964 Tokyo Olympics, when Geesink immobolised Kaminaga in this Kesa-Gatame hold, an entire country fell into collective shock.
