A {{Nihongo|'''''honbasho'''''|本場所|lead=yes}}, or '''Grand Sumo Tournament''' in English, is an official professional sumo tournament. Only ''honbasho'' results matter in determining promotion and relegation for ''rikishi'' (sumo wrestlers) on the ''banzuke'' ranking. Before the 19th century, a wrestler's record at a tournament was of little consequence and the number of ''honbasho'' held every year varied, as did their length. ''Honbasho'' have been organized by the Japan Sumo Association since 1926, following the merger of the Tokyo and Osaka sumo associations. Since 1958, there are six tournaments held over 15 consecutive days in four locations every year. They are held every other month, with the first in January.
==Etymology== The term ''honbasho'' 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 called ''hana-sumo'' ({{lit}} flower-sumo) as it is not taken as seriously by the wrestlers.{{cn|date=January 2026}}
==History== In the Edo period, the locations of sumo tournaments and the ''rikishi'' (sumo wrestlers) who competed in them varied. Sumo was particularly popular in the cities of Edo, Kyoto, and Osaka; with tournaments held twice a year in Edo, and once a year in both Kyoto and Osaka. The tournaments lasted 10 days each.<ref>{{cite web|url=https://nikkan-spa.jp/1715448/3|title=白鵬、鶴竜は休みすぎ? 歴代横綱の休場率を調べてみた|publisher=Nikkan SPA!|language=Japanese|date=2020-11-20 |access-date=2022-12-30}}</ref>
[[File:Kuramae Kokugikan January 1950.jpg|thumb|right|Inside of the Kuramae Kokugikan during the January 1950 ''honbasho'']] In 1926, the newly formed Japan Sumo Association increased the number of ''honbasho'' 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.<ref name="mediaimpact"/> A playoff structure was implemented in 1947 to decide a champion in the case of tied records.<ref name="mediaimpact"/> In 1949, the length of the tournaments was extended from 10 days to 15. In 1958, the number of ''honbasho'' 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 the ''banzuke'' ranks was more closely tied to popularity.<ref name="mediaimpact">{{cite web|last=Singleton|first=James|url=https://www.nippon.com/en/nipponblog/m00133/|title=How the Media Shaped Sumō's Modern Traditions|publisher=Nippon.com|date=2018-01-12 |access-date=2022-12-30}}</ref> In 1884, the ''Yomiuri Shimbun'' began publishing rudimentary summaries of ''honbasho'' results in their newspaper.<ref name="mediaimpact"/> The newspaper ''Jiji Shinpō'' began offering the first award for performances in 1889, giving it to any wrestler who finished a tournament undefeated.<ref name="mediaimpact"/> Other newspapers quickly followed with their own awards. However, these prizes went unclaimed if no ''rikishi'' finished undefeated. Wanting a way to decide a definite winner each tournament, by 1900 daily newspapers such as the Osaka ''Mainichi Shimbun'' had begun bestowing awards on the wrestler with the best record of a ''honbasho''.<ref name="mediaimpact"/> The term ''yūshō'' 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.<ref name="mediaimpact"/> Each division has a championship prize for the wrestler with the most wins. The winner of the top ''makuuchi'' division's ''honbasho'' receives a plethora of trophies and prizes from various organizations, regions and countries, but most notable is the 30kg sterling silver Emperor's Cup.<ref>{{cite web |last=Gunning|first=John|author-link=John Gunning (journalist)|url=https://www.japantimes.co.jp/sports/2018/09/12/sumo/sumo-101-emperors-cup/ |title=Sumo Emperor Cup |publisher=The Japan Times|date=2018-09-12 |archive-url=https://web.archive.org/web/20200924161426/https://www.japantimes.co.jp/sports/2018/09/12/sumo/sumo-101-emperors-cup/ |archive-date=2020-09-24}}</ref><ref>{{cite web|url=https://www3.nhk.or.jp/nhkworld/en/tv/sumo/sumopedia/16/|title=Sumopedia 66: Championship Prizes|publisher=NHK World-Japan|access-date=2022-12-30}}</ref> Since 1947, three special prizes called ''sanshō'' may be awarded to wrestlers in the ''makuuchi'' division for exceptional performances during a ''honbasho''.

The lower division matches begin at 8:30am.<ref>{{cite web|last=Gunning|first=John|url=https://www.japantimes.co.jp/sports/2019/01/18/sumo/sumo-101-wrestlers-typical-tournament-day/#.XEI3UZxKiUk|title=Sumo 101: A wrestler's typical tournament day|publisher=The Japan Times|date=2019-01-18|access-date=2019-01-18}}</ref> As ''honbasho'' results determine promotion and relegation on the ''banzuke'', the first aim for most wrestlers is to achieve ''kachi-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 of ''toshiyori'' a day or two in advance of a tournament day and may be announced from the ''dohyō'' the day prior by a senior ''gyōji''. Although there is no fixed method, for the first half of a tournament the top ''makuuchi'' division will generally see its higher-ranked wrestlers (''san'yaku'') paired against its lower-ranked wrestlers (''maegashira''), with the rest of the ''maegashira'' fighting among ranks closer in strength. The schedule for the second half of the tournament will have mainly ''san'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 of match-fixing where wrestlers will allow another wrestler on the border of a winning and losing record to win and achieve a ''kachi-koshi''; wrestlers with top records will also face each other to increase the possibility of a decisive bout.
Matchmaking in the second-highest ''jūryō'' division works somewhat similarly to the top division, although there are no ''san'yaku''. In the third-highest ''makushita'' 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 same ''heya'' (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 as ''fusenpai''. 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.

The Ryōgoku 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 respective ''honbasho'' begins a week in advance.<ref>{{cite web|url=https://www3.nhk.or.jp/nhkworld/en/tv/sumo/sumopedia/66/|title=Sumopedia 66: GRAND SUMO in Osaka|publisher=NHK World-Japan|access-date=2022-12-30}}</ref> 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 the COVID-19 pandemic in Japan.<ref>{{cite web|url=https://www.japantimes.co.jp/sports/2021/01/29/sumo/spring-basho-tokyo-osaka/|title=Spring Basho moved from Osaka to Tokyo amid pandemic|publisher=The Japan Times|date=2021-01-29|access-date=2022-12-30}}</ref>
===Former venues=== The current Ryōgoku Kokugikan was opened in 1985. Prior to that an arena of the same name hosted ''honbasho'' in Tokyo from 1909 to 1946. From the 1950s through 1984, Tokyo tournaments were held at the Kuramae Kokugikan.<ref>{{cite web |last=Gunning|first=John|url=https://www.japantimes.co.jp/sports/2019/09/10/sumo/sumo-101-kuramae-kokugikan/ |title=Sumo 101: Kuramae Kokugikan |publisher=The Japan Times|date=2019-09-10 |archive-url=https://web.archive.org/web/20190920223928/https://www.japantimes.co.jp/sports/2019/09/10/sumo/sumo-101-kuramae-kokugikan/#.XYVVYO3P3IU |archive-date=2019-09-20}}</ref>
From 1958 to 1964, the July ''honbasho'' was held at Kanayama Gymnasium.

==Cancelled tournaments== The March 2011 tournament was cancelled due to the Japan Sumo Association launching an investigation into allegations of match-fixing involving several ''sekitori''-ranked wrestlers. This was the first cancellation of a ''honbasho'' since 1946, when the May tournament was not held because of renovations to the Ryōgoku Kokugikan following damage sustained in World War II. The May 2011 tournament went ahead but was described by the Sumo Association as a "Technical Examination Tournament" rather than a full-fledged ''honbasho'', with free admission and no prize money or trophies awarded.<ref>{{cite web |url=https://www.japantimes.co.jp/sports/2019/05/20/sumo/sumo-101-cancellations/ |title=Sumo 101: Cancellations|last=Gunning|first=John|date=20 May 2019|publisher=Japan Times|access-date=27 June 2023}}</ref>
