History of Sumo
Sumo's roots run deeper than any other major sport still practiced today — a lineage that stretches from harvest ritual to modern televised spectacle.
Sacred Origins
Sumo's earliest recorded mention appears in the Kojiki (712 CE), Japan's oldest chronicle, which describes a mythical bout between the gods Takemikazuchi and Takeminakata for control of the land. A more grounded account describes a match between the strongmen Nomi no Sukune and Taima no Kuehaya, staged before the imperial court — an event still honored as sumo's symbolic founding.
For centuries, sumo remained tied to Shinto ritual. Matches were performed at shrines as offerings to the gods for a good harvest, and much of the ceremony still surrounding the sport today — the raised ring, the purifying salt, the referee's ceremonial robes — descends directly from these religious roots.
The Edo-Period Professional Era
Organized, spectator sumo (kanjin-zumo) emerged in the 1600s, originally staged to raise funds for temples and shrines. As the sport's popularity grew through the Edo period (1603–1868), permanent sumo stables (heya), a formal ranking system, and the office of the referee (gyoji) all took shape — the basic structure that still governs professional sumo today.
Did you know?
The word sumo derives from the classical Japanese verb sumau, meaning "to compete" or "to struggle."
The Modern Era
The Japan Sumo Association (Nihon Sumo Kyokai) was formally established in the early 20th century to govern the professional sport. In 1958, the calendar settled into its current rhythm: six 15-day grand tournaments (honbasho) held each year in odd-numbered months, alternating between Tokyo, Osaka, Nagoya and Fukuoka.
Legendary figures have defined different eras of the sport — Futabayama's 69-bout winning streak in the 1930s remains the sport's most famous record, while more recent Yokozuna have carried the tradition into the era of international broadcast and a growing global fanbase.
Sumo Today
Modern sumo balances centuries-old ceremony with contemporary professional sport: rikishi still train in traditional stables under strict hierarchy, and every honbasho opens with rituals unchanged for generations — even as the sport reaches new audiences worldwide through streaming broadcasts.
