This is a list of achievements in major international judo events according to gold, silver and bronze medal results obtained by athletes representing different nations.
The objective is not to create a combined medal table; the focus is on listing the best positions achieved by athletes in major global events, ranking the countries according to the most number of podiums accomplished by athletes of these nations.
Invitational-only events were not eligible because they might impose subjective limitations on which athletes are allowed to compete.
Master, Grand Prix and Para meets, such as the Paralympic Games, were not taken into consideration.
The conventions used on these tables are namely: EL for Extra Lightweight; HL for Half Lightweight; LW for Lightweight; HM for Half Middleweight; MW for Middleweight; HH for Half Heavyweight; HW for Heavyweight; OP for Open class; and TM for Team event.
