Rikishi (Japanese: 力士) is the Japanese term for a professional sumo wrestler. The characters literally mean "strong man". In modern Japan rikishi are athletes who compete in regulated tournaments, but they also embody a long cultural tradition that blends sport, ceremony and Shinto-derived ritual. The word applies to all ranked competitors who live and train within the professional sumo world.
Career structure and ranking
Rikishi follow a strict hierarchical system that determines daily duties, pay and tournament seeding. At the top are yokozuna and ōzeki, followed by the junior titled ranks (sekiwake and komusubi) and the maegashira rank which makes up most top-division wrestlers. Promotion and demotion depend on performance in official six-basho (tournament) cycle. Wrestlers adopt a ring name called a shikona, which they use for most of their career.
Life in a stable (heya)
Professional rikishi live and train in communal stables, called heya, run by a retired wrestler who has become an elder (oyakata). Life in a heya is regimented: junior members perform chores, follow set training schedules, and help care for senior wrestlers. Training emphasizes technique, balance and explosive power through daily practice bouts, conditioning and bodywork under the supervision of coaches and senior rikishi.
Rituals, ring and equipment
Competition takes place on the dohyo, a clay ring elevated and bordered by rice-straw bales. Matches are brief and ritualized: before each bout rikishi perform rituals such as stomping and salt scattering to purify the ring. They wear only a heavy silk loincloth called a mawashi during competition and maintain a distinctive topknot hairstyle (oicho-mage), which is also a symbol of rank and tradition.
Physique, diet and techniques
Rikishi are known for a large, powerful physique achieved through targeted training and a high-calorie diet, often centered on chankonabe, a nutrient-dense hotpot that supports mass and recovery. Matches are decided by forcing an opponent out of the ring or making any part of their body other than the soles touch the ground. A wide range of throws and pushes exists, and many rikishi specialize in particular grips or tactics.
When rikishi retire, experienced wrestlers may remain in the Japan Sumo Association as elders if they meet licensing and other requirements; others move into coaching, media or business. The rikishi remain prominent cultural figures in Japan, recognized both for athletic skill and for their role in preserving centuries-old customs surrounding sumo.
