(残った、残った！), which roughly means: "still in, still in!" The gyōji also has the responsibility to encourage the wrestlers to fight when action between them has completely stopped: for instance, when both of them are locked up on each other's mawashi in the middle of the ring. To do this, he uses a phrase similar to that which marked the beginning of the bout: "oi hakkeyoi, oi!" (発気揚々!). If the match time exceeds four minutes with little movement, the time-keeper will usually indicate to the gyōji to call for a mizu-iri, or water break. The gyōji will then record the exact positions of both wrestlers' hands and feet, and put them back in this position once the break has concluded. Additionally, the gyōji may call for a short break if he needs to fix a wrestler's mawashi. Mid-match breaks are rare, but do happen. When a wrestler has apparently fallen to the clay, the gyōji is expected to determine the winner of the bout. His most obvious accessory is a solid wooden war-fan, called a gunbai, which he uses in the prebout ritual and in pointing to the winner's side at the end of each bout, and will often shout "Shobu-ari" ("There is a result"). The gyōji's decision as to the winner of the bout is not immediately final and can be called into question by one of the five shinpan (judges) who sit around the ring. If they dispute the result, they hold a mono-ii (lit: a talk about things) in the center of the ring, and correspond through an earpiece to a further two judges in the video review room. They can confirm the decision of the gyōji (gunbai-dōri or "way of the gunbai"), overturn it (sashi-chigae or "wrong/different indication"), or order a rematch (torinaoshi). The gyōji is not expected to take part in the discussion during a mono-ii unless asked to do so. In many cases, a match may be too close to call, or the gyōji may not have managed to get a clear view of the end of the bout. Regardless, he is still obliged to make a split second decision as to his choice of "winner". This creates pressure on the gyōji, especially considering that a reversed decision (sashi-chigae) is like a black mark. Every time a gyōji's call is overturned they must submit a written report about the ruling to the Japanese Sumo Association.
