He began practicing sumo in sixth grade, later advancing to Hotoku Gakuen High School and Ritsumeikan University before joining the Kasugayama stable to enter professional sumo. After retiring in 2016, he appeared in a popular subscription-based drama series titled Sanctuary.

Sumo boasts a long history as part of Japan’s traditional culture, but its rules and rituals may seem complex to first-time viewers.
This article provides a clear and simple explanation of the fundamental structure and how matches are decided, especially tailored for beginners and foreign audiences.

Basic Rules of Sumo

A sumo match takes place on a circular ring called the dohyō, with a diameter of 4.55 meters. Two wrestlers face off and the first to force the opponent out of the ring or cause any part of their body other than the soles of the feet to touch the ground wins.

Displaying passivity or excessive delayMay result in disqualification

There are no time limits for bouts, and most are decided within seconds. The initial clash, called tachiai, is especially crucial as it often determines the outcome. Ceremonial gestures like salt throwing before the bout also enrich the viewing experience.


Winning Techniques and Prohibited Moves

Sumo recognizes 82 official winning techniques, known as “kimarite”. Some of the most frequently seen are as follows:

Winning TechniqueExplanation
Oshidashi (Push out)Forcing the opponent out by pushing
Yorikiri (Force out)Pushing while gripping the opponent’s belt
Uwatenage (Overarm throw)Throwing by grasping the upper belt
Shitatenage (Underarm throw)Pulling and throwing with the inner belt grip
Tsuri-dashi (Lift out)Lifting the opponent and carrying them out

Sumo also enforces strict rules against dangerous moves. The following are considered fouls and result in immediate disqualification:

Prohibited MoveDescription
Pulling hairGrabbing the opponent’s topknot is forbidden
Twisting fingersDangerous joint manipulation is banned
Excessive throat pushingLimited due to safety concerns
Eye or face attacksStrictly prohibited

When the outcome is unclear, judges hold a consultation called “mono-ii”, and the match may be redone if necessary. This reflects sumo’s commitment to fairness.


Understanding the Sumo Ranking System

Sumo features a strict ranking hierarchy called “banzuke”, which changes based on match results at each tournament. The rankings directly affect salary, status, and match pairings.

RankDetails
YokozunaTop rank; requires dignity and sustained excellence
OzekiSecond-highest; consistent strong performance
Sekiwake & KomusubiKnown as “sanyaku,” upper-middle ranks
MaegashiraGeneral top division wrestlers
JuryoFirst salaried division; called “sekitori”
Lower divisionsNon-salaried ranks below Juryo

Being a sekitori (from Juryo upward) comes with privileges like personal attendants and better living conditions. The banzuke chart is published before tournaments and helps fans understand the wrestler matchups.


Rituals and the Flow of a Bout

Sumo matches include a series of rituals before and after the actual fight, each rich in meaning. Wrestlers enter the ring in groups, purify it by scattering salt, and perform a ritual stance known as “shikiri.”

During shikiri, both wrestlers crouch and stare at each other to time the perfect tachiai. The tension during this moment builds anticipation in the crowd. Once the match begins, the explosive clash and swift resolution are intense and captivating.

The victor returns to the center, bows respectfully, and exits. This is followed by award ceremonies like kensho-kin (prize money) and yumitori-shiki (bow twirling ceremony), making sumo a spectacle that blends tradition with excitement.


How to Enjoy Watching Sumo

Sumo isn’t just about winning or losing. Watching with a deeper understanding reveals layers of tradition, drama, and athleticism.
