Match time period and winning points
The contest period is 5 minutes for adults (men and women), and 4 minutes for juniors (under 20) (boys and girls).
The timer counts down from "5:00" (or "4:00"), and Osae-komi (hold-down) counts occur on the side of the pinned opponent.
Points display from left to right as "Ippon", "Waza-ari", and "Yuko", with the scores displayed above and below. Penalties (including Shido) display to the right of the scores, with the points corresponding to those penalties being added to the opponent's score.
