What is sumo?
Sumo is an ancient Japanese style of grappling with a recorded history of well over a thousand years. In modern amateur competition, the objective is straightforward: force your opponent out of the ring, or make any part of their body other than the soles of their feet touch the ground. The basics are quick to learn, and technical development can continue for years.

Amateur sumo vs Grand Sumo
Grand Sumo is the professional sport competed in Japan under the Japan Sumo Association system, with long-established rituals and ranking traditions.
Amateur sumo is the version trained at clubs and competed worldwide. It is open and inclusive, organised into weight categories, and governed internationally through federation rules. In England, this is the pathway used for club training, domestic events, and progression toward European and World competition routes.
Basic rules of a sumo bout
You win a sumo bout when one of these things happens to your opponent:
- They step or are pushed out of the ring (the dohyo).
- Any part of their body other than the soles of their feet touches the ground inside the ring.
Bouts usually last only seconds, but the technical depth — grip fighting, balance, footwork, and timing — is significant. Sumo does not use punching, kicking, strangles (chokes), or joint locks: it is a pure grappling sport built on movement and balance.
The dohyo (the ring)
The dohyo is the sumo ring. In international amateur sumo (under the International Sumo Federation), the dohyo is a circle of approximately 4.55 m in diameter. The match takes place inside this circle, with a safety run-off area around it.
Weight classes
Amateur sumo uses weight categories so that athletes of all sizes can compete fairly. There are senior men's and women's categories, junior categories for under-18s, and open-weight divisions. See the full breakdown on Sumo weight classes.
Who can do sumo?
Sumo is for all ages, sizes, genders, and abilities. Amateur sumo includes different age groups and weight categories, and beginners do not need to fit a stereotype to take part. Women and girls take part across all levels, and there are junior pathways for children and teenagers at many clubs.
What you need to start
For most beginner sessions, all you need is shorts and a T-shirt, plus water and a willingness to learn. A mawashi can be introduced later as you progress. If a club or event needs anything more specific, it will tell you in advance.
Try sumo in England
The fastest way to start is to visit an affiliated club in England. Most clubs run beginner- friendly sessions and welcome people with no prior martial arts experience.
