Sumo

sports Maturity 7-9 Next article →

Sumo is the national sport of Japan and a form of professional full-contact wrestling.

In a match, two wrestlers compete to force their opponent out of a circular ring called a dohyo.

A wrestler also wins if his opponent touches the ground with any body part other than the soles of his feet. This can happen through shoving, pushing, or throwing the opponent down. While size is often a factor, skill and technique allow smaller wrestlers to defeat much larger opponents. There are no weight divisions in professional sumo, meaning a wrestler might face someone twice his weight.

The mechanics of a match involve specific techniques and strict rules. The Japan Sumo Association recognizes 82 different winning techniques, known as kimarite. Some of these moves are similar to those found in judo. Two common styles are yotsu-zumo, which involves grabbing the opponent's mawashi (belt), and oshizumo, which is a style of pushing without a firm grip. Certain actions are strictly forbidden and called kinjite. These illegal moves include hair-pulling, eye-poking, kicking, or strangulation. The match begins with the tachiai, a synchronized charge by both wrestlers.

Rituals and ceremonies are central to the identity of sumo. Many of these traditions are connected to Shinto, a Japanese religion. Before a bout, wrestlers may toss salt into the ring for purification. They might also rinse their mouths with water, much like the rituals performed before entering a Shinto shrine. Wrestlers perform a warm-up routine called shiko to prepare their bodies.

At the start of tournament days, wrestlers participate in ring-entering ceremonies called dohyo-iri. During these ceremonies, they wear elaborate clothing. The dohyo itself is a raised pedestal constructed of rice-straw bales. It has a diameter of 4.55 meters.

The history of sumo reaches back into ancient times. Prehistoric wall paintings suggest it began as an agricultural ritual dance to pray for good harvests.

Ancient manuscripts from the year 712 describe a wrestling match between gods to decide the possession of Japanese islands. In one legend, the thunder god Takemikazuchi defeated Takeminata by crushing his arm. Another early record from 23 BC describes a match between Nomi no Sukune and Taima no Kuehaya. Nomi no Sukune is regarded as the mythological ancestor of sumo.

During the Japanese Middle Ages, sumo changed from a court ceremony to military training. In 1578, the leader Oda Nobunaga held a massive tournament with 1,500 wrestlers. Because he held many matches at once, he used circular arenas to protect spectators. This event helped lead to the invention of the modern dohyo. During the Edo period, sumo became more organized with professional wrestlers and ranking systems. In 1884, Emperor Meiji organized a tournament that helped restore sumo's popularity.

Life for a professional wrestler is highly regulated and follows strict traditions. Most wrestlers live in communal training stables known as heya.

In a heya, every part of daily life is dictated by tradition, including meals and clothing. This regimented lifestyle can impact health, leading to a lower life expectancy than the average Japanese man. The top division wrestlers have seen significant weight increases over time. In 1969, the average weight was 127 kilograms. By 1991, that average had risen to over 150 kilograms.

Officials ensure that matches are fair and follow the rules. A referee called a gyoji directs the match. He is assisted by five judges who watch the action closely. If a decision is unclear, the judges may call a mono-ii, which is a conference in the middle of the ring. They may even use video reviews to see if a wrestler touched the ground first. In rare cases, a wrestler might be declared a shini-tai, or "dead body." This means the opponent's superior sumo put him in a position where he could not win.
