How Did Sumo Wrestling Start? | Ancient Shinto Origins

The history of sumo is not just a record of sports; it is a timeline of Japan itself. What began as a desperate plea to the gods for rain and rice has evolved into a highly organized professional spectacle. Understanding this evolution requires looking at different eras, from mythological battles to imperial courts and samurai training grounds.

This guide breaks down the timeline, the rituals, and the political shifts that shaped the national sport of Japan.

The Mythological Roots of Sumo

Before human wrestlers entered the ring, Japanese folklore claims the gods fought first. According to the Kojiki (Record of Ancient Matters), the ownership of the Japanese islands was decided by a grappling match.

The god Takemikazuchi fought the god Takeminakata on the shores of Izumo. Takemikazuchi won, establishing the Yamato clan’s dominance over Japan. This legend gives sumo a divine origin status that few other sports possess. It was not merely a test of strength; it was a method of divine judgment.

Early matches were often dedicated to the kami (spirits). Communities gathered at shrines to watch wrestling matches known as Hounou Sumo. The intent was to entertain the gods so they would bless the village with a bountiful harvest. If the wrestling was spirited, the gods were pleased, and the rice would grow.

How Did Sumo Wrestling Start?

When asking how did sumo wrestling start in recorded history, we look to the Yayoi period. Archaeological finds suggest that wrestling rituals accompanied agricultural festivals. These were not sports matches with strict rules. They were rough, dangerous, and deeply spiritual events.

The primary purpose was agrarian. Farmers believed that the earth needed to be awakened or subdued to ensure fertility. The heavy stomping of feet, a move called Shiko that wrestlers perform today, originated here. The stomping was believed to drive away bad spirits from the soil.

During the reign of Emperor Suinin (circa 29 B.C.E – 70 C.E), the first “human” match was recorded. Nomi no Sukune fought Taima no Kehaya. This battle was brutal. It ended only when Nomi no Sukune kicked Taima no Kehaya, breaking his ribs and hip, eventually killing him. This violent beginning contrasts sharply with the strict safety rules of the modern era.

Sumai no Sechie: The Imperial Era

By the Nara period (710–794), sumo moved from the rice fields to the Imperial Court. Emperor Shomu took a keen interest in the sport. He introduced it as part of the Sechie festival. These events, known as Sumai no Sechie, were grand ceremonies held in the palace gardens.

Significant changes during the Imperial Era:

• Geographic gathering — Wrestlers were recruited from all over Japan to compete in front of the Emperor.
• Music and dance — Matches were accompanied by court music and traditional dances, emphasizing the ceremonial aspect.
• Rules formulation — While still rough, basic rules began to form to prevent death, unlike the fight between Sukune and Kehaya.

This period cemented the relationship between sumo and the Emperor. It transformed from a local agrarian ritual into a state-sponsored event. The wrestlers were not professionals yet; they were strongmen or soldiers drafted for the occasion. However, the prestige associated with winning in front of the Emperor laid the groundwork for the professional status that would come later.

The Shift to Military Combat

The gentle court life of the Heian period eventually gave way to the military rule of the Kamakura period (1185–1333). As the samurai class rose to power, the purpose of sumo shifted dramatically. It was no longer just for the gods or the Emperor’s entertainment; it was for survival.

Samurai training applications:

• Armor grappling — Samurai needed to know how to fight if they lost their swords. Sumo provided the base for grappling in armor (Yoroi Kumiuchi).
• Physical conditioning — The training built the leg and core strength necessary to move effectively on the battlefield.
• Mental fortitude — The staring contests and psychological warfare before a match honed a warrior’s focus.

During this military era, the aesthetics of the sport vanished. The focus was on efficiency and brutality. This martial application is where sumo shares a lineage with Jujitsu. Many techniques used to unbalance an opponent in sumo were adapted for battlefield combat where killing the enemy was the only goal.

Warriors like Oda Nobunaga, a powerful daimyo in the 16th century, were avid fans. Nobunaga hosted massive tournaments involving thousands of sumo wrestlers. He is credited with helping to standardize the dohyo (ring), although the defined circle we see today came slightly later.

The Start of Sumo Wrestling as a Profession

Peace eventually returned to Japan during the Edo period (1603–1867). The samurai class had fewer wars to fight, and a wealthy merchant class emerged. This socioeconomic shift created a demand for mass entertainment. This is when sumo truly became a profession.

Kanjin Sumo became the dominant form. Originally, these were charity tournaments held to raise money for constructing or repairing shrines and temples. However, they quickly evolved into commercial enterprises. Promoters began to charge admission fees, and wrestlers began to receive pay.

Development of the Banzuke

The Edo period introduced structure. The Japan Sumo Association traces its organizational roots to this time. The Banzuke, or ranking sheet, was created to track the hierarchy of wrestlers. This document is still written in a unique calligraphy style called Sumo-ji.

Key organizational milestones:

• Stable system (Heya) — Wrestlers began living and training together in communal stables under a master (Oyakata).
• License requirements — Not just anyone could wrestle publicly; promoters required official permission from the shogunate.
• Ring definition — The circular straw ring (dohyo) became the standard battlefield, separating the audience from the athletes.

This era smoothed out the rough military edges. Strikes with fists were banned. Kicking was restricted. The sport became safer for the athletes and more palatable for a general audience. The aesthetics of the ring entrance ceremonies (Dohyo-iri) were refined to show off the strength and dignity of the champions.

Survival During the Meiji Restoration

The Meiji Restoration in 1868 brought rapid Westernization to Japan. Traditional practices were viewed as backward or barbaric. Sumo faced a crisis. The new government considered banning it because the near-nakedness of the wrestlers was seen as an embarrassment in front of Western visitors.

Tactics used to save sumo:

• Emphasis on tradition — Leaders argued that sumo was not just a sport but a repository of Japanese spirit and history.
• Imperial support — A tournament was arranged for Emperor Meiji in 1884. His enjoyment of the matches signaled to the government that sumo was acceptable.
• Nationalism — Sumo was rebranded as the “Kokugi” or national sport, aligning it with the rising nationalist sentiment of the era.

This period is critical because it solidified the “Shinto” elements we see today. The canopy roof (yakata) over the ring, which resembles a Shinto shrine roof, was standardized during this time to emphasize the religious connection. The referee’s clothing was updated to resemble that of a Shinto priest.

Why Do Sumo Wrestlers Throw Salt?

If you ask how did sumo wrestling start utilizing salt, you must look back to the rituals of purification. Salt is a powerful purifier in Shinto belief. Before a wrestler enters the ring, he tosses a handful of salt to cleanse the ground of evil spirits.

This act serves two purposes. First, it is a spiritual cleansing. Second, it is a practical disinfectant. In the past, cuts and scrapes were common, and salt helped prevent infection. Today, it serves as a moment of mental preparation for the wrestler (rikishi).

The quantity of salt thrown can also be a display of spirit. Crowd favorites often throw massive clouds of salt to hype up the audience. It demonstrates energy and a fearless attitude before the bout begins.

The Modern Sumo Association

Today, the Japan Sumo Association (JSA) governs professional sumo. It operates under the Ministry of Education, Culture, Sports, Science and Technology. This keeps the sport aligned with its educational and cultural mission rather than becoming a purely commercial sports league.

There are six Grand Sumo tournaments (Honbasho) held each year. Three are in Tokyo, and one each in Osaka, Nagoya, and Fukuoka. Each tournament lasts 15 days. A wrestler’s rank rises and falls based on his win-loss record during these 15 days.

The hierarchy is strict. At the top is the Yokozuna (Grand Champion). A Yokozuna is expected to display not just physical strength but hinkaku (dignity). If a Yokozuna cannot win consistently, he cannot be demoted; he is expected to retire. This pressure maintains the sanctity of the highest rank.

Foreign Influence on Ancient Origins

While the origins are Japanese, the modern roster is international. In recent decades, wrestlers from Hawaii, Mongolia, Georgia, and Bulgaria have reached the top ranks. This influx has sparked debates about tradition versus globalization.

Impact of international wrestlers:

• Size increase — Foreign wrestlers often brought different body types and dietary habits, pushing the average weight higher.
• Technique evolution — Wrestlers from Mongolia brought judo and wrestling backgrounds, introducing new throwing techniques to the ring.
• Cultural friction — The strict adherence to traditional Japanese etiquette can be difficult for foreigners to master, leading to occasional controversies regarding hinkaku.

Despite these changes, the core rituals remain untouched. A foreign Yokozuna must still perform the ring entering ceremony exactly as a Japanese Yokozuna would have done centuries ago.

Frequently Asked Questions

Who was the first sumo wrestler?

Mythologically, the god Takemikazuchi is considered the first wrestler. Historically, Nomi no Sukune is cited as the human ancestor of sumo after his match in 23 B.C.E. He is now worshipped as a patron deity of sumo wrestlers at certain shrines.

Why do sumo wrestlers wear mawashi?

The mawashi (loincloth) protects the vital organs while allowing the opponent a grip to perform moves. In the Edo period, this became the standard uniform to ensure fairness—it prevented wrestlers from hiding weapons, forcing them to rely solely on technique and strength.

Are women allowed to wrestle in sumo?

Women are banned from professional sumo and cannot enter the dohyo (ring) because of Shinto beliefs regarding purity. However, there is an amateur circuit for women’s sumo, and historical records show that female sumo (Onna-zumo) existed as entertainment in the Edo period.

How much do sumo wrestlers eat?

Wrestlers consume massive calories, often 5,000 to 10,000 daily, primarily through Chanko Nabe. This protein-rich stew helps them build the mass needed for stability in the ring. They eat large meals and then sleep to maximize weight gain.

What happens if a sumo wrestler retires?

Upon retirement, a top-ranked wrestler has a hair-cutting ceremony (Danpatsu-shiki). High-profile figures and friends snip pieces of his topknot (Oicho) before the stable master makes the final cut. Many retired wrestlers become stable masters or coaches.

Wrapping It Up – How Did Sumo Wrestling Start?
