Ippon is the maximum score in judo and ends the match instantly. It is awarded for a throw that puts the opponent largely on their back with control, speed and force; for pinning the opponent (osae-komi) for 20 seconds; or for a successful submission — a strangle (shime-waza) or armlock (kansetsu-waza) that forces the opponent to tap out. Ippon represents the ideal of judo: a single decisive technique executed perfectly. Two waza-ari (half-point scores) also combine to make ippon. The pursuit of the clean ippon throw, rather than winning narrowly on lesser scores, is central to judo’s competitive ideal.

In practice
Ippon — judo's outright winning score, ending the match immediately — can be awarded for a clean, forceful throw landing the opponent largely on their back, a pin held for the required duration, or a submission, which is why judo rewards decisive, technically clean execution over accumulating smaller scoring advantages the way some other combat sports do.
FAQ
How is ippon scored in judo?
A clean throw landing the opponent predominantly on their back with speed, force and control, a pin held for 20 seconds, or a successful submission (armlock or strangle) are the main ways to score ippon.
Does scoring ippon end the match immediately?
Yes — ippon is an instant, outright win, ending the contest regardless of time remaining, unlike lesser scores (waza-ari) which only count toward a points-based decision.
