Ahonbasho (Japanese:本場所), orGrand Sumo Tournament in English, is an official professionalsumo tournament. Onlyhonbasho results matter in determiningpromotion and relegation forrikishi (sumo wrestlers) on thebanzuke ranking. The number ofhonbasho held every year and their length has varied; since 1958 there are six tournaments held over 15 consecutive days in four locations every year. Since 1926 thehonbasho are organized by theJapan Sumo Association, after the merger of theTokyo andOsaka sumo associations.
The termhonbasho means "main (or real) tournament" and is used to distinguish these tournaments from unofficial tournaments which are held as part of sumo tours, between the six major tournaments. Such display tournaments may have prize money attached but a wrestler's performance has no effect on his ranking. This type of sumo is often calledhana-sumo (lit. flower-sumo) as it is not taken as seriously by the wrestlers.
In theEdo period, the locations of sumo tournaments and therikishi (sumo wrestlers) who competed in them varied. Sumo was particularly popular in the cities ofEdo,Kyoto, andOsaka; with tournaments held twice a year in Edo, and once a year in both Kyoto and Osaka. The tournaments lasted 10 days each.[1]
In 1926, the newly formedJapan Sumo Association increased the number ofhonbasho held each year from two to four. In 1928, they introduced rules such as marking uncontested bouts as forfeitures (fusenshō) to help guarantee tournaments end with a clear winner.[2] A playoff structure was implemented in 1947 to decide a champion in the case of tied records.[2] In 1949, the length of the tournaments was extended from 10 days to 15. In 1958, the number ofhonbasho held each year increased again, this time to six.
Before the 19th century, a wrestler's record at a tournament was of little consequence, and promotion through thebanzuke ranks was more closely tied to popularity.[2] In 1884, theYomiuri Shimbun began publishing rudimentary summaries ofhonbasho results in their newspaper.[2] The newspaperJiji Shinpō began offering the first award for performances in 1889, giving it to any wrestler who finished a tournament undefeated.[2] Other newspapers quickly followed with their own awards. However, these prizes went unclaimed if norikishi finished undefeated. Wanting a way to decide a definite winner each tournament, by 1900 daily newspapers such as the OsakaMainichi Shimbun had begun bestowing awards on the wrestler with the best record of ahonbasho.[2] The termyūshō emerged to indicate a wrestler who had finished with a perfect record, but has since come to denote the tournament champion regardless of his record.[2] Eachdivision has a championship prize for the wrestler with the most wins. The winner of the topmakuuchi division'shonbasho receives aplethora of trophies and prizes from various organizations, regions and countries, but most notable is the 30kg sterling silverEmperor's Cup.[3][4] Since 1947, three special prizes calledsanshō may be awarded to wrestlers in themakuuchi division for exceptional performances during ahonbasho.
Withhonbasho lasting 15 days, sumo wrestlers ranked in the top two divisions (makuuchi andjūryō) wrestle once a day, while those of the lower divisions wrestle seven times total, approximately once every alternate day. The lower division matches begin at 8:30am.[5] Ashonbasho results determinepromotion and relegation on thebanzuke, the first aim for most wrestlers is to achievekachi-koshi, or a majority of wins, and thus ensure a promotion for the next tournament. A playoff on the final day is used to decide the winner in case of a tie.
Unless a playoff is required, two wrestlers will fight each other no more than once in a whole tournament. The bout schedule is set by a committee oftoshiyori a day or two in advance of a tournament day and may be announced from thedohyō the day prior by a seniorgyōji. Although there is no fixed method, for the first half of a tournament the topmakuuchi division will generally see its higher-ranked wrestlers (san'yaku) paired against its lower-ranked wrestlers (maegashira), with the rest of themaegashira fighting among ranks closer in strength. The schedule for the second half of the tournament will have mainlysan'yaku fighting each other, with the remainder of the ranks determined by their win–loss records up to that point. One consideration is to minimize the necessity for a tie-breaking bout, particularly if a contender for the championship is lower-ranked and has thus far faced only other lower-ranked wrestlers. In the last day, wrestlers with 7-7 records are scheduled to face each other if possible, to avoid any possibility ofmatch-fixing where wrestlers will allow another wrestler on the border of a winning and losing record to win and achieve akachi-koshi; wrestlers with top records will also face each other to increase the possibility of a decisive bout.
Matchmaking in the second-highestjūryō division works somewhat similarly to the top division, although there are nosan'yaku. In the third-highestmakushita division and below, wrestlers are matched against those with the same record almost without exception, with ranks kept as close as possible. Outside playoff bouts, neither wrestlers from the sameheya (stable) nor wrestlers related by blood are scheduled to fight each other in any division.
If a wrestler has withdrawn due to injury or retirement from a scheduled bout, his opponent wins by default (fusenshō). A loss by default is known asfusenpai. Any remaining bouts that a wrestler misses will be regarded as losses when drawing up the next tournament's rankings. If a withdrawal results in an odd number of wrestlers in one division, the schedule is filled in by pairing a lower-ranked wrestler against a higher-ranked wrestler from the next-lowest division.

TheRyōgoku Kokugikan is owned by the Japan Sumo Association and is therefore the only venue set up for sumo all year round. Preparing the other venues for their respectivehonbasho begins a week in advance.[6] 2020's July and November tournaments and the March 2021 tournament were all held at the Ryōgoku Kokugikan in Tokyo to avoid unnecessary travel during theCOVID-19 pandemic in Japan.[7]
Thecurrent Ryōgoku Kokugikan was opened in 1985. Prior to that an arena ofthe same name hostedhonbasho in Tokyo from 1909 to 1946. From the 1950s through 1984, tournaments were held at theKuramae Kokugikan in Tokyo.[8]
The sumo tournament held in Nagoya every July is scheduled to move from the olderAichi Prefectural Gymnasium (Dolphins Arena) to the new IG Arena starting in 2025,[9] which the Japan Sumo Association will refer to as the Aichi International Arena.[10]
The March 2011 tournament was cancelled due to the Japan Sumo Association launching an investigation into allegations ofmatch-fixing involving severalsekitori-ranked wrestlers. This was the first cancellation of ahonbasho since 1946, when the May tournament was not held because of renovations to the Ryōgoku Kokugikan following damage sustained inWorld War II. The May 2011 tournament went ahead but was described by the Sumo Association as a "Technical Examination Tournament" rather than a full-fledgedhonbasho, with free admission and no prize money or trophies awarded.[11]
The March 2020 tournament wasconducted without spectators due to the recentCOVID-19 pandemic in Japan and surrounding areas.[12] It was the first time since World War II that abasho had been closed to the general public.[12] The move followed a request from theJapanese Government that major public events be cancelled, postponed or scaled down in order to control the spread of the virus.[13] The Sumo Association added that if any of the wrestlers during the tournament were found to be infected with COVID-19, the rest of the tournament would have been cancelled.[13] The May tournament that year was cancelled as the pandemic continued in Japan.[14]
