Scoring

·         Awarding of ippon (一本) 'One full point'. Award of ippon decides the winner and ends the match.

·         Awarding of waza-ari (技あり). 'One half point'. When two waza-ari are awarded in the same match, it is considered to be same as ippon and the match ends (the judge exclaims 'Waza-ari, awasete ippon')

·         Awarding of yuko (有効). One score of waza-ari is considered greater than any number of yuko scores. Yuko is currently the smallest score that can be awarded.

·         Awarding of koka (効果). Was introduced in 1975 and removed from IJF competition at the end of 2008. Any number of koka scores does not add up to a yuko score.
