====== In the event of a disputed result, it is the who can challenge the 's decision by calling in a . When doing so, they correspond through an earpiece to a
video review room, managed by either a single judge (for lower division matches) or two (for matches involving ). Judges have been using replays since the 1969 May tournament. That standard was set after
Taihō was wrongly declared the loser in his match against
Toda during the 1969 March tournament, ending his streak of consecutive victories. Denounced by the press with photographic evidence, the controversy, dubbed the "miscall of the century", prompted the Japan Sumo Association to make video refereeing standard practice. The introduction of video refereeing was a pioneering move in Japanese sports, contrasting with the very traditional nature and setting of sumo. Judges can confirm the decision of the by announcing , overturn it by announcing , or order a . The decision supported by the judges is subject to a majority vote by the members present before being announced to the public. The chief judge then acts as spokesman. Unlike , whose careers are affected if they make too many bad judgments, judges are not affected if they make a bad decision after a controversial match. In the rare case of a judging error, a rematch () can be called. In a
top division match between
Kotozakura and
Atamifuji at the 2025 January tournament, judge Asahiyama (former
Kotonishiki) raised his hand to stop the contest believing that Kotozakura's foot stepped out of the . Video replays confirmed that the foot did not touch the ground outside of the
straw bales at the time the hand was raised, and the judges decided to order a rematch. The accuracy of the judges' decision after a on the spot is never questioned. Its legitimacy is partly based on the fact that, with all sides of the ring covered by the judges, they have a better view of what is happening in the ring than the referee, who will always have a blind spot. In amateur sumo, the use of video refereeing has also become more widespread since the 2020s, following a series of controversial decisions at the highest level of national competition, with the use of tablet computers.
Around and during the matches The judges are divided into seven teams that take turns throughout the day, with two teams dedicated solely to the division, switching places when half of the matches of that division have been completed. Like wrestlers, who must not show emotion, judges must also maintain a neutral expression while officiating. However, it is not uncommon to see judges smile or laugh openly when young teenage professionals struggle to perform their tasks melodiously as they go through
voice change. It is widely accepted that the personalities of judges play a major role in the promotions and demotions of wrestlers. During the meeting, the serve only as observers and are not invited to speak. Three are responsible for recording decisions on promotions and demotions, and their work is then used as the basis for the calligraphy known to the public. In the event of promotion to the rank of , the board of directors considers the request of the judges and forwards it to the
Yokozuna Deliberation Council. In both cases, it is then traditional for a director and a member of the Judging Department to then visit the newly promoted wrestler's
stable to announce the news, which takes place as part of a formal traditional ceremony. It is customary for the board of directors to follow the recommendations of the judges.
Organizing matches and monitor practices The matches are decided by judges during planning meetings, deciding which combinations of wrestlers will compete against each other. As with the deliberations of the , the are also involved in the meeting as they act as clerks during the debates. The matches for the first two days are decided two days before the start of the tournament. From the third day onwards, the matches are decided the morning of the day before, meaning that the next day's matches are decided before the results of the same-day matches are known. The fourteenth and fifteenth days are exempt from this practice, and their matches are decided in the evening, after all matches have been completed. Judges may also reinforce their instructions by issuing warnings to the coaches of wrestlers who break the rules. Recent examples of rules enacted by the Judging Department includes prohibiting a wrestler suffering from a concussion from continuing a match, even if the outcome of the match is being contested. ==See also==
