Sumo wrestling is more than Japan’s national sport โ it’s a millennia-old tradition that blends strength, ritual, and culture. While many see it as a clash of big bodies, sumo began as a sacred Shinto ceremony to pray for good harvests.
When we went to our first sumo tournament, we expected slow, heavy collisions. Instead, we were struck by the wrestlers’ speed, power, and agility. But, the rituals stood out too – the salt throwing, the stomping, and the referee’s robes. It was clearly more than a sport, but we didn’t really understand what we were watching. (A good guide would’ve helped.)
That first experience encouraged us to learn more about sumo.
Since then, we’ve written a series of articles to help others understand what they’re seeing.
This guide draws on ancient texts, archaeological finds, and modern research to explore sumo’s journey from Shinto ritual to professional sport. Along the way, you’ll see how sumo has shaped โ and been shaped by โ Japanese culture, from court ceremonies and samurai training to the tournaments of today.
If you’re curious about sumo’s early roots, its cultural meaning, or how it became the sport it is today, our comprehensive article on the history of sumo wrestling will explain it.

Shinto Origins of Sumo
Sumo began as part of Shinto, Japan’s traditional religion that focuses on nature, ancestral respect, and spirits known as kami.
Back then, sumo wasn’t about sport or competition โ it was a sacred ritual. Matches were held to honour the kami and ask for their blessings, especially for good harvests. These ceremonies often happened during the rice planting season and were seen as a way to pray for or predict how the crops would turn out.
Some of these early traditions are still part of sumo today. Wrestlers stomp their feet to drive away bad spirits and throw salt into the ring to purify it. Even the referees (gyลji) wear outfits inspired by Shinto priests โ a reminder of sumo’s spiritual beginnings.
Historical Evidence
There’s evidence that sumo, or something like it, has been around in Japan for well over 1,000 years. Some of it comes from ancient texts. Some from archaeology.
The Kojiki โ Mythical Roots
The Kojiki (712 CE/AD) โ Japan’s oldest surviving book โ tells a mythical story about two gods wrestling to control the land. Takemikazuchi, a god of thunder and war, defeats Takeminakata, a god linked to farming and hunting. The match is seen as the spiritual beginning of sumo.
In Section 32 of the English translation, Takeminakata demands a trial of strength. He first grabs Takemikazuchi’s hand, which turns into a sword, then a pillar of ice. Takemikazuchi responds by crushing Takeminakata’s arm “like a reed”. Takeminakata then flees and gives up control of the land.
The Nihon Shoki โ First Match Between Mortals
The Nihon Shoki (720 CE/AD) includes the first written account of a sumo match between real people.
It says that in 23 BC, Emperor Suinin ordered a bout between Nomi no Sukune, a potter from Izumo, and Taima no Kehaya, known for his strength. Nomi no Sukune won, breaking Kehaya’s ribs and back with powerful kicks.

You can read Book VI of the Nihon Shoki here. Like many stories from this era, it mixes history and legend, and its accuracy is debated.
There’s a shrine where this first bout is said to have happened. It’s part of the Yamanobe-no-Michi trail in Nara Prefecture โ considered Japan’s oldest road.
Haniwa Figures โ Archaeological Clues
Clay figures called haniwa, dating from the Kofun period (3rdโ7th centuries CE/AD), show people in wrestling poses. These were used in burial rituals, suggesting sumo โ or a similar form of wrestling โ had spiritual or ceremonial meaning long before it became a sport.

Interestingly, Nomi no Sukune (said to have participated in the first bout between people) is also credited with inventing haniwa. Instead of using people as funeral sacrifices, he suggested using clay figures. He became known as the ancestor of a family of potters called the Haji clan.
Sumo in Early Imperial Japan
As Japan entered the Nara and Heian periods, sumo evolved beyond a seasonal ritual. It became part of life at the imperial court, both as a cultural performance and a way to showcase physical strength.
Sumo enters the Imperial Court
During the Nara period (710โ794), sumo started to take on a more official role. According to the Shoku Nihongi, a government post to oversee sumo was created in 719, and ceremonial matches were held for the emperor in 734.
These early bouts were still tied to seasonal customs and were used to entertain the court and assess the strength of potential warriors.
Sumai no Sechie: Sumo at the Heian Court
By the Heian period (794โ1192), sumo had become a major event at the imperial court. The most prominent example was the ‘sumai no sechie‘, or Festival of Wrestling.
Officials sent messengers around the country to recruit strong men from the provinces. On the event day, wrestlers were split into left and right sides and paired off for up to 20 bouts.
These matches were performed before the emperor and court nobles and were accompanied by traditional bugaku music.
The Festival of Wrestling wasn’t just entertainment. It remained a ritual to pray for good harvests and divine the fortunes of the provinces. Sumo kept its spiritual roots, but it was also starting to become a spectacle.
From court display to military training
Unlike earlier sumo, which mainly focused on ritual, Heian-era sumo became more structured. Matches followed formal etiquette, and wrestlers trained to improve their technique and discipline.
During this time, many wrestlers served as imperial or military guards. At first, provinces were expected to supply wrestlers for these roles, but later, they were paid instead, and only top competitors were chosen. After their service, these wrestlers often returned home and took up roles in local government.
By the end of the Heian period, sumo began shifting from a court display to a practical skill for warriors. This type of wrestling, sometimes called buke-zumo, became part of samurai training. That shift laid the groundwork for sumo’s role in the centuries that followed โ both as a way to train fighters and as a growing public spectacle.
Sumo in Feudal Japan
As Japan entered the feudal era, sumo shifted further away from courtly ritual to practical training and entertainment for the warrior class.
Sumo as Samurai Training
During the Kamakura period (1185โ1333), when the samurai class rose to power, sumo became more than just a performance. Feudal lords (daimyล) used it to test the strength and agility of potential warriors. Some skilled wrestlers were even recruited into the samurai ranks.
These matches were rougher and less regulated than what we see today. Sumo bouts during this time were often violent and didn’t follow a formal structure.
The First Sumo Stables
The roots of sumo stables (heya) can be traced to the late 1500s, especially in the Azuchi-Momoyama period (1568โ1600). Though informal, these early groups gave wrestlers more regular training and discipline. Over time, they laid the groundwork for the structured stables that define modern professional sumo.
Nobunaga and the 1,500-Wrestler Tournament
One of sumo’s most powerful early supporters was Oda Nobunaga (1534โ1582), a warlord who helped unify Japan. His support for sumo is well documented in the Shinchล Kลki (Chronicle of Lord Nobunaga), written by his retainer ลta Gyลซichi.
In August 1578, Nobunaga held a grand sumo tournament at Mount Azuchi with 1,500 wrestlers. He introduced circular rings within the castle grounds for multiple bouts to run at once – a step toward the modern dohyล (sumo ring). The layout also improved safety for both wrestlers and spectators.

Nobunaga’s enthusiasm helped push sumo beyond ritual and into the world of competitive sport.
A Popular Pastime Across Japan
By the early 1600s, sumo had grown in popularity and spread far beyond court and military settings. It was well on its way to becoming a recognised pastime throughout Japan, paving the way for its full professionalisation in the Edo period.
The Modernisation of Sumo in the Edo Period
During the Edo period (1603โ1868), sumo changed dramatically. What had once been informal and sometimes chaotic became more structured and professional. Under the Tokugawa shogunate, sumo developed the training systems, rankings, and public tournaments that still define the sport today.
Tokugawa Ieyasu and the Push for Structure
Although Tokugawa Ieyasu was a long-time supporter of sumo, the sport in the early Edo years lacked rules and oversight. Unregulated street matches often popped up in towns and villages. These bouts could be rowdy and occasionally led to gambling problems or fights.
The Tokugawa government introduced clear regulations to bring order to the sport. Sumo was limited to specific venues like temples and shrines, reducing the risk of public disorder and helping sumo take a major step toward legitimacy.

Sumo Tournaments Open to the Public
Previously, sumo had been confined to imperial courts or used for warrior training. But during the Edo period, sumo moved into the public sphere.
Tournaments were often held to raise money for temple repairs or local causes. These events quickly became popular, attracting crowds from all levels of society. The Tokugawa government supported these matches โ as long as they followed official guidelines.
This marked the start of sumo as a form of entertainment for the general public.
The Birth of Sumo Stables
One of the most important developments of this era was the formal creation of sumo stables (heya). While earlier wrestlers often trained on their own or under temporary patronage, the new system brought them into long-term training under a stablemaster (oyakata).
By the mid-to-late Edo period, the heya system had taken hold. It gave sumo structure and discipline, offering:
- A proper environment for training and living
- Clear hierarchy, with younger wrestlers learning from senior ones
- A career pathway from entry-level ranks to the top division
This structure remains the foundation of professional sumo today.
The First Yokozuna
The first recognised yokozuna, Akashi Shiganosuke, appeared in the 1620s. Akashi was said to be 2.58 metres (8 ft 6 in) tall and weigh 340 kg (750 lb).

But at that time, it was an honorary title, not an official rank. Early yokozuna were allowed to perform a special ring-entering ceremony (dohyล-iri) wearing a thick rope, but they didn’t yet sit at the top of the rankings.
Introducing the Banzuke Ranking System
The first known banzuke โ a formal list ranking sumo wrestlers โ was published in 1684. At first, these rankings weren’t consistent across all tournaments. However, by the early 1700s, a clearer system was in place and adopted throughout the country.
Wrestlers were divided into divisions based on skill and performance, with the main ranks being:
- Makuuchi โ top division
- Jลซryล โ second division
- Makushita, Sandanme, Jonidan, and Jonokuchi โ lower and developmental ranks
The system created clear incentives for wrestlers to train hard and advance.
Yokozuna Becomes an Official Rank
By the late 1700s, the yokozuna title shifted from ceremonial to official. Tanikaze Kajinosuke (1750โ1795) was the first wrestler to be formally listed as a yokozuna in the banzuke.
From this point on, yokozuna were not just strong wrestlers โ they represented the highest rank in the sport.
The change reflected sumo’s growing professionalism and the increasing expectations placed on its top athletes.
Sumo in the Meiji Period
When Japan entered the Meiji period (1868โ1912), the country was rapidly changing. Western ideas were flooding in, and many traditional practices were questioned. Sumo wasn’t immune. Some saw it as outdated or too crude, especially with its near-naked wrestlers and religious overtones. Public interest dropped, and there were even calls to ban the sport altogether.

But in 1884, sumo received a major boost. A special exhibition was held for Emperor Meiji, featuring top wrestlers Umegatani I and ลdate. The emperor’s support helped restore sumo’s reputation and confirmed its place in modern Japan. From that point, sumo worked hard to adapt without losing its traditions.

The Building of a Permanent Home for Sumo in Tokyo
For much of the Edo and early Meiji periods, tournaments were held at open-air venues such as Ekล-in Temple in Tokyo’s Ryลgoku district. Temporary wooden structures were built next to the temple to host the events, but they offered little protection from the weather and limited spectator comfort.
The First Ryลgoku Kokugikan (1909โ1944)
In 1909, sumo got its first indoor arena โ the original Ryลgoku Kokugikan. Built next to Ekล-in, it had a capacity of about 13,000 and marked a turning point in how sumo was viewed as a public spectacle.


However, the building faced several disasters:
- 1917 โ A fire destroyed the arena’s roof. Matches were moved to Yasukuni Shrine until it was rebuilt and reopened in 1920.
- 1923 โ The Great Kantล Earthquake caused significant damage. Tournaments were again temporarily relocated, this time to Nagoya.

- 1944โ1945 โ During World War II, the building was requisitioned by the Japanese military for balloon bomb production and suffered extensive damage from air raids. It never reopened and was eventually dismantled.

The Creation of the Japan Sumo Association
As sumo continued to evolve, it became clear that stronger central governance was needed. On 28 December 1925, the Japan Sumo Association was officially established under the name Zaidan Hลjin Dai Nihon Sumล Kyลkai. This marked a key shift in how the sport was managed.
Before this, regional factions and individual promoters organised tournaments with little standardisation. The new association created a unified structure, overseeing rankings, stables, rules, and tournament operations โ laying the foundation for the modern professional sumo system.
Sumo After World War Two
Like much of Japan, sumo had to recover and rebuild after World War II. With Tokyo heavily bombed and the original Ryลgoku Kokugikan damaged beyond repair, tournaments were held at temporary venues, including baseball stadiums and public halls, as the country regained its footing.
Despite the upheaval, sumo remained a popular draw and helped lift national spirits in the postwar recovery.

Kuramae Kokugikan (1950โ1984)
After the war, the damaged Ryลgoku Kokugikan was eventually torn down, and sumo needed a new venue. The Kuramae Kokugikan was built in the Kuramae neighbourhood in Taito Ward, Tokyo, to become the new permanent home of sumo. Tournaments were held there from 1950 to 1953 while it was still under construction, but it was officially completed in September 1954.

It introduced several upgrades, including:
- An interior roof (called the tsuriyane) suspended above the ring by cables was installed in 1952, designed without the traditional supporting pillars of the previous tsuriyane. It gave spectators a clear view from all angles.
- Heating
- A new space for the Sumo Museum

This stadium became the main venue for tournaments for over 30 years. While it wasn’t as iconic as Ryลgoku, it kept the sport going and allowed sumo to rebuild its fan base. However, it began to show its age, so planning began to return sumo to Ryลgoku in a new purpose-built arena.
The Second Ryลgoku Kokugikan
In 1985, sumo returned to its spiritual home of Ryลgoku with the opening of the new Ryลgoku Kokugikan โ a modern stadium that still hosts three of the six annual tournaments today. With a capacity of over 11,000, the new arena brought sumo back to where it belonged.

Sumo Goes Global: International Tours and Foreign Wrestlers
After World War II, sumo started gaining attention outside Japan. In 1965, top wrestlers like Taihล and Kashiwado took part in goodwill matches in the Soviet Union, helping introduce the sport overseas. These tours sparked a growing interest abroad.
In the 1960s, wrestlers from outside Japan began making their mark in sumo. Hawaiian-born Takamiyama became the first foreign wrestler to win a top division championship in 1972. He was followed by Konishiki, also from Hawaii, who was promoted to ลzeki in 1987, becoming the first foreigner to reach that rank. Akebono, another Hawaiian, made history as the first non-Japanese yokozuna in 1993.โ
European wrestlers also found success: Kotoลshลซ from Bulgaria reached ลzeki in 2005, and Baruto from Estonia achieved the same rank in 2010. Mongolian wrestlers like Asashลryลซ, Hakuhล, and Terunofuji have dominated the upper ranks in recent years.โ
In 2025, two Ukrainian wrestlers reached the top makuuchi division. Aonishiki, aged 21, made his debut in March and achieved an impressive 11โ4 record, earning the Fighting Spirit Prize. His compatriot Shishi, 28, returned to the top division for his second appearance and secured a solid 9โ6 record. Their achievements highlight sumo’s growing international diversity.
Places to Explore If You’re Interested in Sumo History
If sumo has caught your interest and you’re visiting Japan, there are some great spots to explore that bring the sportโs long history to life.
Sumo Museum (Tokyo)
Located inside the Ryลgoku Kokugikan stadium in Tokyo, the Sumo Museum is a small but fascinating stop. Established in 1954, it features rotating displays of sumo-related items like woodblock prints, ceremonial aprons, and photos of famous wrestlers.
Entry is free, but if you’re visiting during a tournament, you’ll need a valid ticket to get in. Be aware itโs a small space โ good for a quick visit if youโre already at the Kokugikan.
Sumo Sites Near Nara
Nara is best known for its temples and deer park, but itโs also linked to some of the oldest sumo stories.
Sumo Shrine โ Sakurai City, Nara Prefecture
The Sumo Shrine (Sumo Jinja) is traditionally seen as the birthplace of sumo. This is where the first recorded match between mortals โ Nomi no Sukune vs Taima no Kehaya โ is said to have taken place around 23 BCE, during Emperor Suininโs reign.
The shrine has a sumo ring and monuments marking this early event. Itโs a peaceful spot to reflect on the sportโs spiritual origins and can be reached via a short bus ride from Sakurai Station. It’s also part of the Yamanobe-no-Michi trail โ Japanโs oldest road.

Kehayaza Sumo Museum โ Katsuragi City, Nara Prefecture
Dedicated to Taima no Kehaya, this museum has around 13,000 documents and artifacts tied to early sumo history. Youโll also find a full-sized sumo ring you can walk around and learn from.
The Kehayaza Sumo Museum is a five-minute walk from Kintetsu Taimadera Station and makes a great side trip for sumo fans staying in Nara or Osaka.
Viewing the Kojiki and Nihon Shoki Texts
The Kojiki (712 CE) and Nihon Shoki (720 CE) are the oldest written sources mentioning sumo โ including both the mythological match between gods and the first recorded human bout.
The original manuscripts no longer exist, but early copies are sometimes displayed at major museums like the Tokyo National Museum and the Kyoto National Museum during special exhibitions. Check their schedules ahead of time if you’re hoping to view them.
You can also access English translations online:
- Kojiki โ translated by Basil Hall Chamberlain (1882). See Section 32 for the story of Takemikazuchi and Takeminakata.
- Nihon Shoki โ translated by William George Aston (1896). Book VI includes the story of Nomi no Sukune.
