SUMO 101
The national sport of Japan, sumo, is rich in history and tradition. Wrestlers adhere to a strict lifestyle,
and unlike American sports, there is no off-season.
SUMO TERMS
Chanko-nabe = A rich and filling stew with vegetables such as tofu, cabbage and bean sprouts mixed
with seafood, chicken, pork or beef, and seasonings.
Heya = A “sumo stable,” the building where sumo wrestlers eat, sleep and train.
Mawashi = A heavy silk loincloth or belt worn by a sumo wrestler during a bout. Many winning
tricks involve maneuvers with a grip on the opponent’s mawashi.
Rikishi = Literally, “strong man,” a general term for sumo wrestlers.
Sumotori = Another term for rikishi, or sumo wrestlers.
HISTORY
Sumo is a form of wrestling with deep origins in Japanese legend and history. The sport dates back
over 1,500 years. Ancient wall paintings suggest sumo was performed in prehistoric times as part of
agricultural rituals for the gods to determine the success of farmers’ crops. Several stories exist of
sumo matches held in the seventh and eighth centuries as part of Imperial court ceremonies. In
1909, sumo was established as the national sport of Japan. Today it is a widely popular form of
professional entertainment.
LIVING ARRANGEMENTS
Sumo wrestlers must join a sumo stable, or heya. This is where they live, eat, sleep and train
throughout their career. An average heya contains about 15 wrestlers. Life is hierarchical, with lower-
ranked wrestlers cooking, serving and doing chores for the higher-ranked wrestlers. The stable
master or higher-ranked wrestlers may hit others with bamboo sticks as a form of discipline.
DIET
Sumo wrestlers begin their day with a hard practice, so they do not eat breakfast. Lunch is a
communal meal of chanko-nabe, a nutritious, high-calorie stew which is served with large portions of
rice and many side dishes. Wrestlers eat huge amounts of food and nap immediately following a
meal in order to gain weight.

ATTIRE
Rikishi practice and wrestle in a mawashi, a thick belt about 30 feet in length that is wrapped around
the body several times and knotted securely in the back. It can weigh around 10 pounds. During
practice, wrestlers wear mawashi made of canvas; during tournaments, professionally-ranked wrestlers
wear mawashi made of silk. Depending on their wrestling styles, some sumo wrestlers wear their
mawashi very tight, so an opponent cannot get a good grip, or somewhat loose, because the slack
helps them to avoid being jerked quickly.
Anytime a rikishi leaves the sumo stable, he must dress in the traditional Japanese kimono or yukata
(light cotton dressing gown). Whether in practice or outside of the heya, a sumo wrestler must wear
his hair in a chonmage, or topknot. During tournaments or special occasions, a higher-ranked wrestler
wears his hair in an elaborate oichomage, which resembles a ginkgo leaf.
TRAINING
Each day, younger and lower-ranked wrestlers must wake for practice first, around 4 or 5 a.m.
Practice consists of many flexibility and strength exercises, followed by challenge matches.
Shiko = Stomping in large, sweeping motions,

alternating legs. Shiko is a form of both exercise and
ritual; it is done both to train the lower half of the body
and to sweep away evil spirits underfoot.
Shiko
Suriashi = Leg strengthening exercise done
in a crouched position. A wrestler bends
his elbows with his hands in front and steps
forward with alternating legs, keeping low
to the ground.
Suriashi
Matawari = Thigh splits. A wrestler must sit in a split

position and lean forward until his stomach touches
the ground. If he cannot do it alone, another wrestler
will hold his legs or
push him down.
Matawari
Sonkyo = Squatting down with a straight back,

hands placed on the knees, breathing deeply,
sonkyo is almost a meditative state.

RANKING
Sumo wrestlers are ranked in a pyramidal hierarchy. A winning record allows a wrestler to move to a
higher ranking, while a losing record moves him to a lower ranking. Lifestyle and treatment inside
and outside of the heya is based on this ranking.
The top five rankings are collectively referred to as the makuuchi division. The highest ranking is
yokozuna, or sumo Grand Champion. Only a very small handful of wrestlers have achieved this
status. The next highest ranking below the makuuchi division is called juryo. Only one in ten wrestlers
achieves this status. All other rankings below juryo are still apprentice stages. A juryo wrestler is
considered a professional. He begins to receive a monthly salary as well as other bonuses and perks,
such as receiving permission to marry, having attendants assigned to take care of his personal needs,
and wearing a silk kimono and mawashi.
TOURNAMENTS
There are six major sumo tournaments (basho) a year, held every other month and lasting two weeks
each. Various exhibitions are held between tournaments, but they have no affect on the ranking
system.
Centered inside a sumo arena is the dohyo, an 18-square-foot clay area where the sumo bouts take
place. The inner ring is 15 feet in diameter, covered in sand and marked by straw bales. The dohyo is
blessed by a Shinto priest prior to tournaments. A gyoji is a sumo referee.
Wrestlers participate in a variety of pre-bout rituals, including shiko leg stomps and throwing salt to
drive away evil spirits and purify the ring. Opponents face each other, crouch down and place their
knuckles on the ground, staring at each other in a sort of mental battle, called niramiai. The sumo
match begins at the moment of tachiai, the initial clash when
opponents rush at each other in synchrony with great force.
Matches are often determined at this moment.
A bout is lost if a wrestler steps or is forced out of the ring,

or touches the ground with anything but the soles of his feet.
Punching, eye-poking, and kicking above the knees are
among the illegal sumo moves.
After a match, both wrestlers again face each other on

opposite sides of the ring and bow.
