What is a Sumotori?

A sumotori needs to be large and capable of defeating their opponent in a gruelling fight. In Japan, the preferred term for a sumo wrestler is “rikishi”, which means “mister” and “strength”, showing their respect for the sacred combatant. Rikishi train from a young age in a heya, “stables” or “training quarters” where they also live. They’re used to eating food designed to gain weight. Most rikishi weight at least 22st but they can weigh as much as 34st, albeit while drastically reducing their life expectancy.

The combatants fight barefoot in the dohyo (ring) wearing just a maetate-mitsu (codpiece) with a belt known as a mawashi. Each rikishi’s hair is styled in keeping with tradition and according to their rank. Furthermore, each rikishi has their shikona or ring name. There’s an established ranking for the rikishi from apprentice (uchi-deshi) to professionals (sekitori). However, there are ranks granted to great champions.

Sumo Rules and Rituals

Rikishi fight in the dohyo which represents the heavens and is 6m². The match itself takes place in a 4m-diameter ring in the centre of the dohyo. There’s a ceiling hanging over the ring, making the arena a sanctuary and the match is dedicated to the gods.

Before starting the fight, there are several rituals for washing the rikishi’s body and spirit. They’ll rinse their mouths with water and clean their bodies with a paper towel. To protect them from injury, they’ll purify the ring with salt. To win, the rikishi needs to push their adversary out of the ring of onto the floor of the dohyo. Only a rikishi’s feet are allowed to touch the ground. They also lose if they touch the bags of straw surrounding the combat area. In sumo, you cannot throw punches or kick above the hips, strangle, or pull hair. You cannot grab the maetate-mitsu of your opponent either.

The history of sumo is intertwined with Japanese history: the first mention of sumo wrestling can be found in the Kojiki, a chronicle of Japanese history dating back to 712. According to legend, a sumo match decided who controlled the Japanese islands.

The gods Takemikazuchi and Takeminakata fought on the Shimane beach. Outside of legend, it’s difficult to say exactly when sumo wrestling arose in Japan. It seems that sumo wrestling was used as an agricultural ritual to bring about a good harvest. There were no illegal blows and these fights were to the death. In the Nihon Shoki, sumo was said to have begun between mortals around 23BCE. The first winner, Sukune, is said to be the father of sumo. Interested in Japanese culture? Find out more about geishas.

Sumo Throughout History

During the Nara Period (8th century), sumo wrestling was introduced to the imperial court and an annual festival was organised. There were several festivals in the Imperial Palace of Emperor Shomu. Thus, sumo was no longer an agricultural ritual but a ritual for peace and prosperity.

Sumo became a martial art during the reign of Emperor Saga (9th century) and the warrior class practised the sport from the 12th century. Several great Japanese military chiefs were fans of sumo including Minamoto no Yoritomo and Nobunaga Oda. During the 17th century, the rikishi started becoming professionals and entertainers for the Japanese elite. This is also when the first rings surrounded by bags of straw. They started burying them during the 18th century. During the Edo Period, the great daimyos became the sponsors for sumos grand champions. In addition to a salary, the rikishi also earnt the title of samurai. Modern sumo wrestling was developed during the Edo Period: the Kanjin-zumo was used to raise funds for buildings, sanctuaries, repairing temples, bridges, and other public works. The official ranking system was also introduced during the Edo Period. Official organisations were formed and merged during the 20th century, leading to the modern Sumo Kyokai. Now you know a bit more about Japanese culture and the national sport. If you want to learn even more, consider reading our other articles on Japan or getting Japanese language lessons from a private tutor on Superprof! There are three distinct types of private tutorial on offer for Japanese students: face-to-face tutorials, online tutorials, and group tutorials. Each type is different in terms of learning styles and cost, so what may be right for one student may not be right for another. Face-to-face tutorials involve just a single student and tutor and will include a bespoke programme or course that's being taught to the student. You will be getting a tailored service which is very cost-effective! Online tutorials also involve one student with a tutor but the two aren't physically in the same place. Thanks to the internet, you can be taught Japanese online via webcam. With fewer travel costs and the ability to schedule more tutorials each week, the tutor doesn't need to charge as much for their tutorials. Group tutorials are more like the classes you would've had in school with one teacher and multiple students. With each student footing the bill, the cost per student per hour tends to be less than the other two types of tutorial.  Don't forget that a lot of tutors on Superprof offer the first hour of tuition for free, too!
