Judo Rules

Judo, a martial art and sport known for its emphasis on grappling techniques, traces its roots back to Japan. The art was founded by Jigoro Kano in 1882, who sought to develop a system that would allow individuals to use their opponent’s strength and energy against them. Over the years, Judo has evolved into a popular global sport, promoting physical fitness, mental discipline, and mutual respect among practitioners. Its techniques and principles continue to be widely studied and practiced in dojos around the world.

Judo aims to achieve victory by using an opponent’s strength against them, promoting balance, harmony, and personal growth in both sport and life.

  • A half-point score given for a throw that lacks the full impact required for an Ippon but still places the opponent on their back with considerable control and force.
  • A lesser score awarded for a throw that demonstrates some control but lacks the force or impact of an Ippon or Waza-ari.
  • The lowest score, given for throws that show minor control or impact but do not meet the criteria for higher scores.
