It is a combat game which originated from the Chinese and Japanese as a way of self-defence without the use of weapons. JUDO means GENTLE WAY (JU means Gentle and DO means way or principle).

Professor Jigoro Kano took up the sport and developed it to the accepted stage throughout the world. He established the Kidokan School of Judo in 1882 in Tokyo. He was named the father of Judo by the International Olympic Committee.

The International Judo Federation is the governing body with the headquarters in Berlin, Germany. The Nigeria Judo Association was established in 1973.

Nature of the Game

The two contestants (JUDOKAs) will come to the mat facing each other at a distance of about 3 – 5 m. each will put on a JUDOGI.

At the referee’s signal, the contestants bow to each other, grasp each other’s jacket and begin the match.

  2. The gripping

  2. Judokas must not apply joint lock other than elbow locks.
  3. The contestants are prohibited from biting, pinching and chocking.
  4. Judokas should not wind the end of the belt or jacket around any part of the opponent’s body.
  5. They should not leave the area for any reason, except as a result of a technique or action of the opponent.
Weight Categories

As in most combat sports, this is also divided into weight categories, so you only fight with someone with a similar weight to yours, thus being a fairer and more balanced fight.

The weight categories and their weights are:

  1. Extra lightweight (up to 60 kg)
  2. Lightweight (up to 66 kg)
  3. Lightweight (up to 73 kg)
  4. Average medium weight (up to 81 kg)
  5. Average weight (up to 90 kg)
  6. Medium weight (up to 100 kg)
  7. Heavyweight (over 100 kg)
Field of Judo

The Judo field is called a mat and is a square area, formed by thin mattresses of 2 meters long by 1 meter wide, and they fit so as to make the mat.

This must have a size between 14 meters and 16 meters total, being that it is divided into three areas:

  1. Combat Area:

This is located in the center of the mat, measuring between 8 and 10 meters aside. This is where the judokas fight and score points. There are only two marks in this area that indicate where each one of them must begin and end the combat.


  1. Hazardous area:

This area is marked by red colour and is around the combat area, taking 1 meter wide. It is red to warn the judokas who are leaving the scoring zone and to apply the manoeuvre or return to the combat area.


  1. Security area:

The security area only exists to give some clearance to the judo if they leave the combat area, measuring it 3 meters wide. Here, it is no longer possible to rate.
