Ancient Origins of Sumo Wrestling
The origins of sumo wrestling stretch back deep into Japanese prehistory. Archaeological evidence, including clay figurines known as haniwa discovered in burial mounds, suggests that wrestling-like contests existed in Japan as far back as the Yayoi period (roughly 300 BCE–300 CE). These early forms of competitive grappling were not yet "sumo" as we know it today, but they represent the earliest physical evidence of wrestling culture on the Japanese islands.
The word "sumo" itself is believed to derive from an Old Japanese term meaning "to compete" or "to strike one another." Ancient texts describe muscular men engaging in bare-handed struggles with few rules — a raw, primal contest that gradually became codified over centuries of cultural refinement.
Unlike many sports whose origins are murky, sumo is unusual in that it has a rich written record in Japanese historical chronicles. The sport's development can be traced through religious texts, imperial court documents, and later through the records of professional sumo organizations.

Mythological Roots: When Gods Wrestled for Japan
To understand the history of sumo, one must first understand its deep entanglement with Shinto mythology. According to the Kojiki (Record of Ancient Matters, compiled around 712 CE) and the Nihon Shoki (Chronicles of Japan, completed around 720 CE), the very ownership of the Japanese islands was decided by a wrestling match between two gods.
The deity Takemikazuchi, a god of thunder and swords, challenged Takeminakata, a god associated with wind and agriculture, to a contest of strength. Takemikazuchi won decisively, establishing divine authority over the land. This mythological bout is often cited as the very first sumo match, and it elevated the sport to a spiritual plane that it has never fully left.
A second famous mythological contest involves the mortal hero Nomi no Sukune, who is said to have fought a violent wrestler named Taima no Kehaya before Emperor Suinin around the 3rd century CE. According to the Nihon Shoki, Nomi no Sukune kicked Taima no Kehaya to death — a far cry from the refined rules of modern sumo, but a story that established the sport's imperial connections. Nomi no Sukune is revered to this day as the "patron saint" of sumo, and a shrine in his honor stands in Tokyo near the Kokugikan sumo arena.
Sumo in the Nara and Heian Periods (710–1185)
It is during the Nara period (710–794 CE) that sumo first became an institutionalized activity within the Japanese imperial court. In approximately 726 CE, Emperor Shomu is believed to have organized a formal sumo viewing as part of harvest festival celebrations. This marked the beginning of Sechie Sumo — official sumo tournaments held at the imperial palace.
By the Heian period (794–1185), Sechie Sumo had become a major annual event on the imperial calendar. Wrestlers were summoned from provinces across Japan to compete before the emperor. The matches were deeply ritualistic, incorporating prayers for a good harvest, protection from evil spirits, and divine favor. The dohyo (the ring in which sumo is contested) itself evolved from a sacred space defined only by spectators standing in a circle to a more formally designated area.
Rules during this era were still relatively loose by modern standards. Striking with fists was permitted, and matches could be quite violent. Over time, however, the imperial court began to refine the rules, bringing the sport closer to the form we recognize today. During the Heian period, sumo also began to develop a distinct aesthetic — wrestlers wore elaborate ceremonial garb, and the contests were accompanied by music and ritual chanting.
Key Fact: Sechie Sumo
The annual Sechie Sumo tournament at the imperial court, established during the Nara period, is considered the first formalized sumo competition in Japanese history. It ran continuously for centuries, establishing many of the rituals still present in sumo today.
Medieval Sumo: Kamakura Through Sengoku Periods (1185–1603)
As Japan entered its feudal age, sumo's character transformed dramatically. With the rise of the warrior class (the samurai) during the Kamakura period (1185–1333), sumo became a critical part of military training. Samurai practiced sumo to develop physical strength, balance, and grappling techniques that could prove vital on the battlefield. The sport shed much of its purely ceremonial nature and took on a harder, more martial edge.
This martial embrace of sumo reached its peak during the Sengoku period (the "Warring States" era, roughly 1467–1615), a time of near-constant civil war in Japan. Several of the era's most powerful warlords were passionate supporters of sumo. Most famously, the great unifier Oda Nobunaga was an ardent sumo enthusiast who reportedly organized large sumo tournaments at Azuchi Castle, reportedly gathering as many as 1,500 wrestlers for competition. Nobunaga used these events both for entertainment and to identify talented, physically powerful men who might serve in his armies.
His successors, Toyotomi Hideyoshi and later Tokugawa Ieyasu, also patronized sumo, cementing the sport's status as a pastime of the powerful. During this period, many of the basic techniques and throws that define sumo today began to be catalogued and named, forming the foundation of the official list of recognized winning techniques (kimarite) that governs the sport today.
The Edo Period: The Rise of Professional Sumo (1603–1868)
The Edo period was arguably the most transformative era in the history of sumo. With Japan unified under the Tokugawa shogunate and enjoying a long peace, sumo evolved from a military exercise and imperial spectacle into a professional commercial entertainment. It was during the Edo period that sumo as we know it today was truly born.
Early in the Edo period, itinerant wrestlers (called tsuji sumo, or "street sumo") performed in public spaces for donations. The authorities frequently cracked down on these events as disorderly. To bring structure to the sport, Buddhist temples and Shinto shrines began hosting organized sumo tournaments as a means of raising funds for construction and maintenance. These kanjin sumo (charity sumo) events proved enormously popular and helped standardize the rules and format of competition.
By the mid-Edo period, the first permanent sumo organizations emerged in the great cities of Osaka and Edo (modern-day Tokyo). Around 1757, organized sumo in Edo began operating on a regular seasonal schedule. The system of ranking wrestlers — the banzuke — was formalized, providing a clear hierarchy from the lowest beginners to the exalted champions. The rank of yokozuna, the grand champion, was officially recognized, though it took further decades to become fully codified. Read our full guide to sumo ranks and the banzuke.
The dohyo (the clay ring) also took on its definitive form during the Edo period. The circular ring marked with a rice-straw bale boundary (the tawara), the elevated clay platform, and the suspended roof modeled after a Shinto shrine roof (yakata) all became standardized. The elaborate pre-match rituals — the leg stomps (shiko), salt throwing, and the tachiai (initial charge) — became formalized as part of the sumo ceremony.
The Birth of the Yokozuna
The first wrestler to receive a yokozuna license from the Yoshida family (the traditional authorities on sumo rank) was Akashi Shiganosuke, who is regarded as the 1st Yokozuna, though historical records from his era are incomplete. The title became more formally recognized with wrestlers such as Miyagiyama and, most famously, Tanikaze Kajinosuke, the 4th Yokozuna, who dominated sumo in the late 18th century with a remarkable winning record and is celebrated as one of the greatest wrestlers in the sport's history.
The Meiji Era and the Modernization of Sumo (1868–1912)
The Meiji Restoration of 1868 brought dramatic upheaval to Japan as the country rapidly modernized and Westernized. For sumo, this was a period of existential crisis. Western sports and ideas flooded into Japan, and there were serious debates about whether a sport so deeply tied to feudal culture and Shinto ritual had a place in modern Japan. Some reformers advocated for abolishing sumo entirely.
Sumo survived — and thrived — largely due to imperial patronage. Emperor Meiji attended a sumo tournament in 1884, effectively bestowing imperial legitimacy on the sport and signaling that sumo was not a relic to be discarded but a treasured national tradition. This endorsement transformed sumo into a symbol of Japanese national identity, a role it has maintained ever since.
The Meiji era also saw significant organizational reforms. In 1925, the Japan Sumo Association (Nihon Sumo Kyokai) was formally established to govern professional sumo, unifying the previously separate Osaka and Tokyo sumo organizations (the merger of the two organizations was finalized around 1925). This consolidation created a single national governing body that standardized rules, rankings, tournament schedules, and wrestler training across the country.
Sumo in the 20th Century
The 20th century brought both tremendous challenges and remarkable growth to sumo. World War II (1939–1945) severely disrupted the sport, as Japan's military mobilization left little room for entertainment. Tournaments were suspended or significantly reduced during the war years, and the Kokugikan arena in Tokyo (first built in 1909) was repurposed for non-sumo uses, including as a military goods distribution center and later an ice skating rink during the post-war occupation.
The post-war recovery of sumo was remarkable. As Japan rebuilt, sumo re-emerged as a powerful symbol of national resilience and cultural pride. In 1958, the Japan Sumo Association expanded the number of official tournaments per year from four to six — the system still in place today. Each of these tournaments (honbasho) lasts 15 days, with each wrestler competing once per day.
The advent of television in Japan proved transformative. Sumo broadcasts began on NHK in the 1950s, and by the 1970s and 1980s, sumo was one of Japan's most-watched sports. The television era created the first truly nationally famous sumo stars. Wrestlers like Taiho, who won an extraordinary 32 tournament championships and dominated the sport in the 1960s, became household names across Japan. His rivalry with Kashiwado captivated the nation, and together they were known as "Hakuho and Taiho" — a popular cultural expression of the era.
The Internationalization of Sumo
One of the most significant developments of the late 20th century was the emergence of foreign-born wrestlers at the top levels of sumo. The first non-Japanese wrestler to reach the rank of sekitori (a top-division professional) was Takamiyama (Jesse Kuhaulua from Hawaii), who debuted in professional sumo in the 1960s and became a popular figure in Japanese sumo culture. His success opened the door for a wave of foreign talent.
By the 1990s, Hawaiian-born wrestlers such as Konishiki, Akebono, and Musashimaru had risen to the highest levels of the sport. Akebono made history in 1993 by becoming the first foreign-born wrestler to be promoted to yokozuna. This achievement was both celebrated and controversial, sparking ongoing national conversations in Japan about cultural identity and the nature of sumo as a national sport.
Contemporary Sumo: The Global Era
The 21st century has seen sumo reach unprecedented global visibility, even as it has navigated significant internal controversies. The early 2000s brought a wave of Mongolian wrestlers who would come to dominate the sport in a way never seen before. Wrestlers like Asashoryu and, most remarkably, Hakuho, rewrote the record books entirely.
Hakuho Sho (born Mönkhbatyn Davaajargal in Ulaanbaatar, Mongolia) is widely considered the greatest sumo wrestler of all time. He accumulated approximately 45 tournament championships over the course of his career before retiring in 2021 — a record that far surpasses any wrestler in history. His technical mastery, mental composure, and physical dominance redefined what was possible in the sport.
The dominance of Mongolian wrestlers — who have held the yokozuna rank continuously for much of the 21st century — has prompted significant cultural debate within Japan. Supporters celebrate the sport's international quality; critics worry about the impact on sumo's identity as a Japanese tradition. This tension reflects a broader question the sport continues to grapple with: how to honor ancient tradition while embracing a globalized world.
Sumo has also had to navigate scandals. In 2011, a serious match-fixing scandal (yaochō) led to the cancellation of a tournament for the first time since World War II and significant reforms within the Japan Sumo Association. The organization has since implemented more rigorous governance and transparency measures.
Today, sumo is broadcast to audiences around the world, with growing fan bases in Europe, the Americas, and across Asia. English-language commentary, international streaming services, and social media have made sumo more accessible than ever to non-Japanese audiences.

Key Historical Stats and Milestones
Frequently Asked Questions About Sumo History
How old is sumo wrestling?
Sumo wrestling has a documented history of more than 1,500 years, with references to wrestling contests appearing in the Kojiki (compiled 712 CE) and Nihon Shoki (720 CE). Archaeological evidence of wrestling culture in Japan may extend even further back, potentially to the Yayoi period (around 300 BCE–300 CE). The formalized sport with standardized rules began developing during the Nara and Heian imperial court periods.
What is the mythological origin of sumo?
According to Japanese mythology recorded in the Kojiki and Nihon Shoki, the ownership of the Japanese islands was decided by a wrestling match between the gods Takemikazuchi and Takeminakata. A second foundational story involves the mortal hero Nomi no Sukune, who reportedly defeated a violent wrestler before Emperor Suinin. Nomi no Sukune is honored as sumo's patron saint, with a shrine dedicated to him near the Kokugikan arena in Tokyo.
When did sumo become a professional sport?
Professional sumo developed gradually during the Edo period (1603–1868). It grew from itinerant street performances and charity tournaments held at temples and shrines into an organized commercial entertainment with regular schedules, formal rankings (the banzuke), and stables (training houses for wrestlers). By the mid-18th century, professional sumo organizations operated in both Edo (Tokyo) and Osaka, and these were eventually unified under the Japan Sumo Association, formally established around 1925.
Who was the first foreign-born yokozuna?
Akebono (Chad George Haaheo Rowan), a wrestler from Hawaii, became the first foreign-born wrestler to be promoted to yokozuna, receiving the promotion in January 1993. He became the 64th Yokozuna in sumo history. His promotion was both celebrated as a sign of sumo's international appeal and controversial among those who felt the honor should remain exclusive to Japanese-born wrestlers.
Who is considered the greatest sumo wrestler of all time?
Hakuho Sho (Mongolian-born Mönkhbatyn Davaajargal), the 69th Yokozuna, is widely regarded as the greatest sumo wrestler in history. He won approximately 45 tournament championships during his career — far more than any other wrestler in recorded sumo history — before retiring in 2021. His technical mastery, consistency, and longevity at the top of the sport set him apart from all who came before him.
What is the Kokugikan and why is it important in sumo history?
The Kokugikan is sumo's premier arena, located in the Ryogoku district of Tokyo. The first Kokugikan was built in 1909, marking the establishment of a permanent, dedicated venue for sumo. The current Kokugikan, opened in 1985, hosts three of the six annual official tournaments (January, May, and September). The arena is central to sumo's identity and includes a sumo museum that documents the sport's long history.
How has sumo changed over the centuries?
Sumo has evolved dramatically from its origins. Ancient sumo permitted striking with fists and had few formal rules. Gradually, through the Heian court period, the Edo professional era, and modern governance by the Japan Sumo Association, the rules were refined. Punching is no longer allowed. The circular clay dohyo, the 15-day tournament format, the six annual tournaments, the formal ranking system, and the elaborate pre-match rituals all developed over centuries. The sport has also globalized, with wrestlers from Mongolia, Eastern Europe, and elsewhere now competing at the highest levels.
What role did the Edo period play in sumo's development?
The Edo period (1603–1868) was the single most formative era in sumo's development. During this time, sumo transformed from a military exercise and imperial ritual into a professional commercial sport. Key Edo-period developments include: the formalization of the banzuke ranking system, the establishment of the yokozuna rank, the standardization of the dohyo (clay ring with tawara straw-bale boundary), the founding of training stables (heya), and the emergence of sumo as popular mass entertainment in Japan's great cities.
Why do sumo wrestlers throw salt before a match?
The ritual of throwing salt (known as shio) before a sumo match is rooted in Shinto religious practice. In Shinto belief, salt is a purifying substance that cleanses the dohyo (wrestling ring) of evil spirits and impurities, protecting both wrestlers and ensuring a fair contest. This ritual, along with the leg-stomping exercises (shiko) and other pre-match ceremonies, dates back to the sport's origins as a Shinto religious practice performed before the gods and emperor. The salt-throwing ritual remains one of sumo's most recognizable and beloved traditions.
How many official sumo tournaments are held each year?
There are six official sumo tournaments (honbasho) held each year, each lasting 15 days. This schedule has been in place since 1958. The tournaments are held in January (Tokyo), March (Osaka), May (Tokyo), July (Nagoya), September (Tokyo), and November (Fukuoka). Each wrestler in the top divisions competes once per day throughout the 15-day tournament. Learn more about how sumo tournaments work.
