Sumo is a traditional Japanese sport where two wrestlers, called rikishi, compete in a circular ring. The goal is to force the opponent out of the ring or to make any part of their body, other than the soles of their feet, touch the ground. Matches are often quick and intense, showcasing strength, balance, and technique. Sumo has deep cultural significance in Japan, with rituals and ceremonies that date back centuries. Wrestlers live in stables, where they train and follow strict diets. The sport is governed by a set of rules and ranks, with the highest rank being yokozuna.
