Sumo, Japan's national wrestling sport, keeps an explicitly Shinto ritual frame around every professional bout in a way most major modern sports have long since shed, and the ritual elements are not treated as vestigial decoration but as an integral, structurally central part of the event: the dohyo, the raised clay ring in which bouts take place, is itself consecrated with offerings, traditionally salt, rice, dried squid, chestnuts and other items, buried at its centre before it is used, and a suspended roof built in the style of a shrine roof hangs above the ring, marking the space visually and religiously as sacred ground rather than ordinary sporting territory. Wrestlers throw handfuls of purifying salt into the ring before a bout, a Shinto purification gesture directly paralleling the harae rites performed at ordinary shrine visits, and the deliberate, ritualised stamping, shiko, wrestlers perform as part of their pre bout preparation is understood within sumo's own tradition as driving away evil spirits from the ring, an act of ceremonial purification built directly into the sport's standard preparatory choreography rather than an optional flourish left to individual wrestlers' discretion.
