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'' ( flower-sumo) as it is not taken as seriously by the wrestlers.
History
In the
Edo period
The , also known as the , is the period between 1600 or 1603 and 1868 in the history of Japan, when the country was under the rule of the Tokugawa shogunate and some 300 regional ''daimyo'', or feudal lords. Emerging from the chaos of the Sengok ...

In 1926, the newly formed

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.
A playoff structure was implemented in 1947 to decide a champion in the case of tied records.
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.

The newspaper ''Jiji Shinpō'' began offering the first award for performances in 1889, giving it to any wrestler who finished a tournament undefeated.
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 ''

The term ''

Format
With ''honbasho'' lasting 15 days, sumo wrestlers ranked in the top two divisions (''makuuchi'' and ''
jūryō'') 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. As ''honbasho'' results determine

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.

'' 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. 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.
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, tournaments were held at the
Kuramae Kokugikan in Tokyo.
Future venue
The sumo tournament held in Nagoya every July is scheduled to move from the older
Aichi Prefectural Gymnasium (Dolphins Arena) to the new IG Arena starting in 2025, which the Japan Sumo Association will refer to as the Aichi International Arena.
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

. 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.
The March 2020 tournament was
conducted without spectators due to the recent
COVID-19 pandemic in Japan and surrounding areas.
It was the first time since World War II that a ''basho'' had been closed to the general public.

that major public events be cancelled, postponed or scaled down in order to control the spread of the virus. 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.[ The May tournament that year was cancelled as the pandemic continued in Japan.]
