Sumo is a traditional form of Japanese wrestling that has evolved into a dynamic and energetic modern sport, now enjoyed in many countries all around the world. The compact arena, measuring just 4.55 meters across, is where the action unfolds. The wrestler who steps out of the area first, is thrown out, or touches the ground with any body part besides their feet, loses the match. This simple yet strict set of rules, combined with the short and intense bouts, make sumo an exciting and engaging spectacle. Physical and mental training in sumo is demanding, as the outcome of a match often hinges on a single explosive moment, where the wrestler's body, skills, and spirit must work together in harmony. Sumo strictly upholds principles of courtesy and etiquette, and the various rituals involved symbolise how the wrestlers must engage each other fairly, and the art's noble values are respected.

The popularity of sumo has led to the organization of many tournaments, both in Japan and overseas. Currently, the International Sumo Federation has over 90 affiliates.
